1. remove redundant SPI clock settings, use rom functions to set clock.
2. remove redundant SPI cs setup and hold settings.
3. for old 32Mbit psram, cs hold time must only be 0.5T due to the special driving mode.(cs_setup = 0; cs_hold = 0)
4. for new 64Mbit psram, cs hold time is recommended to be 2.5T. (cs_setup = 1, cs_setup_time = 0;cs_hold = 1, cs_hold_time = 1)
Fix following WiFi STA certification issues:
1. Add support for STA HT2040 coexist management
2. Add support for WPA2 improvements
3. Disallow HT rate when unicast/mcast cipher is TKIP/WEP
Earlier eraseItem function in Storage class would do lazy cleanup of
multi-page blobs if called using type "ANY" instead of "BLOB". It used to
just delete BLOB data and index would remain as is. Any subsequent read
would delete index entry as well. This however would return a valid
length without error if nvs_get_blob API was just used for finding
length and not reading the complete blob. This change fixes this issue.

esp32: fix the issue that the spike transmit power of WiFi is higher than configured when WiFi and Bluetooth coexist (backport v3.1)
See merge request idf/esp-idf!4614
Fixed adjtime function: While using the adjtime() function,
the time correction accumulated an error
when reading the time frequently (using gettimeofday).
update TC_IT_MESH_EST.yml and TC_IT_MESH_COMM.yml
change mesh ci case form T50 to T12 in gitlab-ci.yml
add some test ENV in components/idf_test/integration_test/TEST_ENV_SSC.yml
The requirements of pin capabilites is different for spi master and
slave. The master needs CS, SCLK, MOSI to be output-able, while slave
needs MISO to be output-able.
Previous code is for master only.
This commit allows to place other 3 pins than MISO on input-only pins
for slaves. Refactoring for spi_common is also included.

mdns_search_once_t::lock is used to synchronize tasks (taken by one
task and given by the other) so it should not be a mutex.
Convert to semaphore, and rename to indicate its purpose.
Issue: MDNS server initially sends probing packets to resolve naming confilicts with already registered service instances. In case of a conflict, instance name is altered and probing restarts. Original instance however wasnnot removed from the structure and upon service removal only one entry was removed and a dangling service might have been kept in the structure to bring about a crash.
Resolution: Keep only one instance of a service in the probing structure.
possible race condition: user task runs mdns_init, which enables pcbs while mdns-task already created could execute enable/disable of the same pcbs if an appropriate system event received
mnds_free() initiates stop and delete timer tasks, which after locking the mutex could lead to a dead lock in case timer task executed before deleting the task, as it would wait indefinitelly for unlocking the mutex. This condition is fixed by calling _mdns_stop_timer without locking the mutex, because there's no need to protect any data when stopping and deleting the timer task
Issue: mdns_service_add API allocates and queues an action to be processed in mdns task context; when allocation or queueing fails, allocated structure needs to be freed. Function _mdns_free_service did not only fee all the structures, but also updates packet data.
Resolution: Moved removal of packet data outside of _mdns_free_service function.
packets scheduled to transmit are pushed to action queue and removed from tx_queue_head structure, which is searched for all remaining services and while service is removed, then service questions/asnwers are also removed from this structure. This update fixes possible crash when packet is pushed to action queue, and when service is removed, its answers are removed from tx_queue_head, but not from action queue. this could lead to a crash when the packet is poped from action queue containing questions/answers to already removed (freed) service
Previously, this compiler flag was not being applied
regardless of CONFIG_SPIRAM_CACHE_WORKAROUND setting.
Explanation: add_compile_options() only applies to
source files added after the function is run, or in
subdirectories added after the function is run. In
this case, no new source files were being added after
this function was run.
when running a query for a single txt, result entries were not created and attached to result structure. this issue was introduced when fixing memory leak in txt structure, which worked correctly for PTR queries, but caused trouble for TXT query.
Files where stack protector is initialized should not be compiled with
stack protector enabled. This was done for Make but missing for CMake.
Fixes https://github.com/espressif/esp-idf/issues/2990.
When xPortGetCoreID() is called twice within a function,
it might only be called once after compilation. This
commit makes the inline assembly of the function volatile.

Fix following WiFi bugs:
1. Fix the bug that STA incorrectly deletes BA when receiving DelBA request
2. Add out of memory check
3. Fix the bug that STA incorrectly receives packets when scanning in connected status
Previously when HashList was removing items, HashListBlocks were
removed lazily. This resulted in empty HashListBlocks dangling around
in full pages, even when all items have been erased. These blocks
would only be deleted when NVS was re-initialized
(nvs_flash_deinit/nvs_flash_init).
This change does eager cleanup instead, based on the code from
@negativekelvin offered in
https://github.com/espressif/esp-idf/issues/1642#issuecomment-367227994.
Closes https://github.com/espressif/esp-idf/issues/1642.
1. ref_clock used in unit tests occasionally produces time off by ~100
microseconds shortly after being started. Add a delay to let
ref_clock stabilise, until the cause is found.
2. Reduce roundoff error accumulation which would occasionally cause
the test to fail, by choosing an overflow value which can be divided
by APB frequency.
3. Move time sampling part of the test into an IRAM function to
reduce variations due to cache behavior.
4. Remove calculation of "standard deviation" in the test, as what was
calculated was not actually standard deviation, and it did not add any
useful information.
1. call esp_timer_get_time and ref_clock_get in the same order on
start and in the loop
2. disable interrupts when calculating delta between ref_clock
and esp_timer
3. ensure both functions are in cache before calculating the delta
In the situation when bootloader was compiled for 240MHz, and app was
compiled for 160MHz, and the chip is a revision 0 chip, the
bootloader will assume that the application has also been running at
240MHz. This will cause the chip to lock up later. Modify this to use
a run time check of DPORT_CPUPERIOD_SEL, which indicates which of the
PLL frequencies was used.

1. In original driver, the stack size for emac driver task "emacT" is only 2048 Bytes, which also can not be changed by user.
2. Each time when invoking "emac_start" function, it will reset emac registers, the driver should reconfig some important registers again.

1. Add missing get function to RMT API: rmt_get_idle_level().
2. Suppress error message from rmt_wait_tx_done() if wait_time==0 (allows for polling).
3. Remove the blank lines between parameter lists.

fix 3 bugs:
1. do BLE connect (both of slave and master), it mgiht cause crash due to there's much interrupts happens effect ble code running, for example, wifi run on the same core as bluetooth controller and wifi run throughtput test.
2. do BLE scan stop or adv stop or connection stop, it might cause ASSERT or crash due to memory corrupted in controller memory poll.
3. minor bug fix, not really effect bluetooth.
The bug will cause memory corrupted (the largest range is from 0x3ffc0000 ~ 0x3ffc8000),
some strange error will happen, like IllegalInstruction, LoadProhibited and .etc.
Fix following WiFi bugs:
1. Fix a crash bug which is caused by WiFi static TX buffer alloc/free.
2. Fix the bug that iphone fails to connect to ESP32 AP by enabling AP BAR receiving.
3. Fix the bug that ESP32 station fails to connect some APs, such as Xiaomi hotspot etc,
after reset.
This commit adds the ability for backtracing to trace from the itnerrupt to the
task stack, and across nested interrupts. Test cases have also been added.
See merge request !4084
Note: "Test backtrace from abort" reset reason modified by removing abort as a reason.
Shortcircuit evaluation may cause skip of _mdns_strdup_check of any further question field, which after clear_rx_packet freed undefined memory.
Fixes https://ezredmine.espressif.cn:8765/issues/28465
Originally, when doing BLE active scan, Bluedroid will not report adv to
application layer until receive scan response. This option is used to
disable the behavior. When enable this option, Bluedroid will report
adv data or scan response to application layer immediately.
Previously, hardware SHA engine "locks" were mutex semaphores. This meant that the task which
started a particular SHA session (in hardware) needed to finalise that session, or an invalid
FreeRTOS state was created.
Replace with binary semaphore which can be shared between tasks.
Includes a unit test, but unit test doesn't crash even without this fix
(some other unknown condition is required).
Bootloader used to calculate the number of cache pages assuming that
load address was aligned, while in reality load address for DROM and
IROM was offset by 0x20 bytes from the start of 64kB page. This
caused the bootloader to map one less page if the size of the image
was 0x4..0x1c less than a multiple of 64kB.
Reported in https://esp32.com/viewtopic.php?f=13&t=6952.
In some cases, linker could choose to use ROM functions instead of the
ones defined in IDF.
For functions used in ROM stub table, this would lead to infinite
recursion when the corresponding function was called from ROM.
For crypto functions, some of these were modified in IDF, and
incompatible with ROM counterparts.
If zero-overhead loop buffer is enabled, under certain rare conditions
when executing a zero-overhead loop, the CPU may attempt to execute an invalid instruction. Work around by disabling the buffer.
Due to a hardware limitation in ESP32, the first four bytes of some
CSI data is invalid, not the last four bytes.
Correct a mistake of CSI sub-carrier index in documentation.

1. Change bus reset to handle interrupted READ sequences.
2. Slow down I2C to 100khz during reset
3. If a SLAVE device was in a read operation when the bus was interrupted, the SLAVE device is controlling SDA.The only bit during the 9 clock cycles of a byte READ the MASTER(ESP32) is guaranteed control over, is during the ACK bit period.
If the SLAVE is sending a stream of ZERO bytes, it will only release SDA during the ACK bit period. The master(ESP32) cannot generate a STOP unless SDA is HIGH. So, this reset code synchronizes the bit stream with, Either, the ACK bit, Or a 1 bit.
I am stealing this delay coding from @jeremyherbert #2493 pr.
2. Change Bus Reset to handle interrupted READ sequences.
The current code does not handle interrupted READ cycles.
If a SLAVE device was in a read operation when the bus was interrupted, the SLAVE device is controlling SDA.
The only bit during the 9 clock cycles of a byte READ the MASTER(ESP32) is guaranteed control over, is during the ACK bit period.
If the SLAVE is sending a stream of ZERO bytes, it will only release SDA during the ACK bit period. The master(ESP32) cannot generate a STOP unless SDA is HIGH.
So, this reset code synchronizes the bit stream with, Either, the ACK bit, Or a 1 bit.
3. fix typo
correct `sda_id` to `sda_io` in `i2c_master_clear_bus()` @ryan-ma found it. This typo was generated when I manually edited this patch on GitHub, I should have done a Copy/Paste operation!
1. fix bug PHY/RTC functions called in ISR (update phy to v4007)
2. add UnitTest to test it
3. fix task watchdog bug when wifi change channel
4. disable/enable agc to mac deinit/init
5. add UnitTest Job
state and reduce force receiving broadcast data time
1. If receiving beacon which indicates that there is no data
buffered, do not force to receive WiFi data.
2. If receiving beacon which indicates that there is broadcast data
buffered, reduce the time to force receiving broadcast data.
timer_process_alarm function of esp_timer holds a spinlock for the
entire duration of its operation, except for the time when timer
callback function is called. It is possible that when
timer_process_alarm releases the spinlock, a higher priority task may
run and delete the timer. Then the execution will return to
timer_process_alarm, and this will either cause a crash, or undesired
execution of callback after the timer has been stopped or deleted.
To solve this problem, add a mutex which will prevent deletion of timers
while callbacks are being dispatched.
A workaround to reset BBPLL configuration after light sleep. Fixes the

On enabling flash encryption, OTA fails with magic byte error in the second chunk
if the http data is split into two or more chunks and first chunk is less than 16.
This fix includes following changes:
1. Fix the bug that esp_restart()/esp_wifi_stop() sometimes fails in WiFi/BT coexist mode.
2. Add a timer for WiFi stop and stop WiFi forcibly once the timer expires.
1. start an esp_timer on entering sleep to acquire pm_lock before wake up from modem sleep
2. decrease the clock division of XTAL fed to bluetooth low power clock from 32us to 2us period to allow to work under 240MHz Max CPU frequency
3. decrease the minimum sleep duration threshold to allow shorter bluetooth modem sleep period, especially for BLE with short connection interval
4. reconfigure bluetooth baseband(BT-BB) settings after PHY/RF init upon waking up from modem sleep to avoid packet RX/TX performance degradation
