This change adds esp_deep_sleep_get_wakeup_cause, which returns the
source which has caused wakeup from deep sleep.
Similar to esp_deep_sleep_get_ext1_wakeup_status, a function is added
to check touch pad wakeup status: esp_deep_sleep_get_touchpad_wakeup_status.
This function returns the touch pad which has caused wakeup.
ULP and touch FSMs in ESP32 revisions 0 and 1 do not operate correctly
if RTC_PERIPH power domain is force powered on (ESP_PD_OPTION_ON).
Both ULP and touch still work, but clock frequency of the ULP may be
incorrect and touch values may be off by considerable amount. As such,
when these wakeup modes are used, RTC_PERIPH power domain has to be set
to ESP_PD_OPTION_AUTO (or, in the current implementation,
ESP_PD_OPTION_OFF — though this will change in the future when _OFF will
actually *force* the power domain to be powered off).
Because EXT0 wakeup source requires RTC_PERIPH to be powered ON, mark
ULP and touch wakeup sources as incompatible with EXT0. Workaround for
this is to use EXT1 wakeup source instead, which offers similar or
better functions without having to keep RTC_PERIPH powered on.
1. add new APIs bt controller enable/disab/deinit
2. make bt controller work need to call two APIs of esp_bt_controller_init and enable
3. modify phy init to make mac reset once
Also add steps to disable flash encryption, as some people seem to
accidentally enable it.
Explicitly mark the flash encryption and secure boot as "READ DOCS
FIRST" in menuconfig.
docs: use custom roles to generate GitHub links
This change replaces direct links to GitHub master branch with
auto-generated links using docutils custom roles.
These auto-generated links point to the tree or blob for the git commit
ID (or tag) of the repository. This is needed to ensure that links don’t
become broken when files in master branch are moved around or deleted.
The following roles are introduced:
```
- :idf:`path` - points to directory inside ESP-IDF
- :idf_blob:`path` - points to file inside ESP-IDF
- :idf_raw:`path` - points to raw view of the file inside ESP-IDF
- :component:`path` - points to directory inside ESP-IDF components dir
- :component_blob:`path` - points to file inside ESP-IDF components dir
- :component_raw:`path` - points to raw view of the file inside ESP-IDF
components dir
- :example:`path` - points to directory inside ESP-IDF examples dir
- :example_blob:`path` - points to file inside ESP-IDF examples dir
- :example_raw:`path` - points to raw view of the file inside ESP-IDF
examples dir
```
A check is added to the CI build script, which searches RST files for
presence of hard-coded links (identified by tree/master, blob/master,
or raw/master part of the URL).
This check can be run manually: cd docs && make gh-linkcheck
Additionally, Sphinx linkcheck build type is used to create new CI test,
which check for broken links. This test has to be triggered explicitly,
because including it in normal build process (when the commit is not yet
deployed to Github) will not work. It can be triggered in a regular
fashion using a combination of cron and Curl, similar to stress tests.

Organize examples and API documentation - supplement to !430
This supplement to !430, both intended to replace bulky !421.
1. Fixed broken links
2. Added links to available examples in API documentation, where missing
3. Updated links to point directly to example folder (to show README.md with example description)
4. Added README.md in docs folder info to point reader to ReadTheDocs instead of doc sources, ref. https://github.com/espressif/esp-idf/issues/243
5. Fixed some typo errors / Sphinx warnings
6. Fixed memory leak in example, ref. https://github.com/espressif/esp-idf/issues/209
See merge request !440
Most of the packages mentioned are only needed for building the toolchain using crosstool-NG, not for the normal ESP-IDF environment.
Mention that pyserial needs to be installed (fixes https://github.com/espressif/esp-idf/issues/229).
esp32 core dump to flash
1. menuconfig option to select where to store core dump: flash, uart or disable
2. Saving of core dump to flash
3. Partition table definitions files with core dump partition
4. Python scripts to support core dump generation from GDB command line
See merge request !341
The following issues mentioned during MR!341 review were fixed:
1) Core dump test application description
2) Usage of CONFIG_ESP32_ENABLE_COREDUMP_TO_FLASH and CONFIG_ESP32_ENABLE_COREDUMP_TO_UART
3) FLASH_GUARD_START macro usage is fixed in flash API
4) Core dump module logging facility
5) cache util functions doc updated
6) interactive delay before print core dump to uart
7) core dump partion support in build system
component bt:Added the create attribute table method to the new API
GATT Server service table APIs.
Have already modify the style and other things as @jeroen suggestion in other MR(the MR have been closed)
See merge request !399
update toolchain version, rebuild newlib
- This MR updates the toolchain version used in the ESP-IDF
- Compiler version check and warning is added to project.mk
- Newlib is rebuilt to include wcsftime function
- libstdc++ build uses correct newlib headers (so we won't get undefined reference to `__impure_ptr` anymore)
See merge request !387
ethernet: support flow control
(1) Only fullduplex mode support flow ctrl .
(2) Fix reboot exception which caused by not-reset EMAC hardware (such as DMA) when reset CPU.
See merge request !392
component/bt: bug fix of lack of checking bluetooth stack status inside API functions
Add an API function for checking bluetooth stack status: whether it is uninitialized, initialized or enabled.
The function is intended to be used by users to check the bluetooth stack status, also, it is used inside bluetooth API functions to ensure the stack is in valid state.
See merge request !405
build system: add IDF_VER environment variable and preprocessor define
This adds an `IDF_VER` preprocessor define which is obtained from `git describe`.
Looks like `v1.0-275-g0efaa4f` for non-release version or `v2.0` for a tagged (release) version.
See merge request !403
SDMMC peripheral driver, SD protocol driver, FATFS library, VFS integration
This MR contains:
- SDMMC host peripheral driver
- SD protocol driver in sdmmc component (can be extended to support MMC/eMMC and SPI based hosts)
- ChaN's FATFS library v0.12b
- VFS integration
- FAT access via VFS is thread-safe (unless same file is read/written/unlinked/renamed from different tasks)
- Support for POSIX directory-related functions in VFS (and in vfs_fatfs.c)
- unit test for the above
- Example
- API documentation
Will be done in other MRs:
- Support for spi_flash IO driver for FatFs
- SPI host driver and support for SPI mode commands in sdmmc component
- MMC/eMMC support in sdmmc component
- Support for slightly higher 53/26.6MHz clocks (currently I'm using 20MHz for DS and 40MHz for HS, instead of 25MHz/50MHz per standard), and arbitrary low clocks (e.g. 4MHz).
See merge request !353
Enable bootloader entropy source for RNG
Enables an entropy source when bootloader starts up, which both seeds the RNG for use before WiFi/BT stack is enabled and provides an adequate RNG for secure boot & flash encryption key generation.
A prerequisite was enabling 80MHz operation, so the CPU is now set to 80MHz as soon as second stage bootloader starts running.
See merge request !363
SPI master driver
This merge requests adds an SPI Master driver. This driver is (of course) multithread capable, has device abstraction, has command queueing, DMA support and all other sorts of nice things you'd expect from a SPI driver.
See merge request !332

GPIO driver: add per-pin interrupt handlers
1. add ISR handler apis so that users of different layers can hook their own isr handler on different GPIO.
Audio project has different software layers, they need different gpio isr handler for layer instead of processing all GPIO interrupts in one handler.
If this kind of calling a handler from isr is not proper, please kindly point out.
2. add gpio example code.
3. update gpio doc.
