spi test: Prime the flash cache before each test to minimise flash cache misses.
VFS performance test: Increase the number of runs to minimise influence of an isolated bad run.
driver(i2c, rmt): Add xQueue and xSemaphore static allocation support when intr_alloc_flag set to ESP_INTR_FLAG_IRAM.
See merge request idf/esp-idf!2335
1. provide options for bluetooth low power mode
2. provide two options for bluetooth low power clock: main XTAL and external 32kHz XTAL
3. provide function and callbacks to control bluetooth low power mode, including enable/disable sleep, software wakeup request, low power clock settings, check power state, etc
4. modify vhci API vhci_host_send_packet to use blocking mode
5. note that DFS and bluetooth modem sleep can not be used together currently.
This fixes errors logged on the console: sdmmc_req:
handle_idle_state_events unhandled: 00000004 00000000
The issue happens if "data done" event occurs before "command done".
State machine code did not check *which* event occurred in
SENDING_CMD state, and went to IDLE or SENDING_DATA state on any
non-error event. In this case, we can't process "data done" event
until command has completed. This change introduces "unhandled event"
mask, which is carried over from one run of process_events to the
other. This allows waiting for the "command done" event to complete,
and then process "data done" event.

CMD53 in byte mode supports transfers of any number of bytes between 1
and 512. This change removes limitation that the number of bytes must
be divisible by 4. Host quirk, that such transfers must be split into
two commands (one for the aligned part and the other one for
unaligned) is taken into account.
1. Fix the duty fade check issue reported from https://github.com/espressif/esp-idf/issues/1914
2. Fix the duty overflow issue when duty_scale is set to 1.
3. Fix the duty fade error when a fade operation is under way. We must configure a new duty setting after the previous fade operation has finished due to hardware limit.
4. Add thread-safe version APIs to set duty and fade.
5. Correct the duty range in driver.
It has been observed that, if external SPIRAM is enabled, then under
certain scenarios (e.g. internal memory being too much fragmented),
I2S tx/rx descriptors can land in external SPIRAM and hence resulting
in failure in DMA. Adding explicit capability to allocate in only DMA
capable memory.

Command response tokens can be delayed from the original command by 1
to 8 bytes. In 4a2489b9, handling for delayed tokens was added for
normal (no data) commands, and data read commands. This adds handling
for delayed commands for data write commands.
Previous version of the code only connected CD and WP to the
peripheral, in fact the hardware does not use the values of these
signals automatically. This adds code to read CD and WP values when
command is executed and return errors if card is not present, or
write command is executed when WP signal is active.
