esptool version bump and new "espefuse.py set_flash voltage" command
* New "espefuse.py set_flash_voltage" command to easily set a fix
VDD_SDIO regulator voltage (1.8V, 3.3V or disabled).
* Fixes bugs when flashing files with non-4-byte aligned lengths
(doesn't effect esp-idf image files)
* esptool README improvements
* Detect overlapping files in write_flash
* read_mac now works correctly on ESP32
* Integrates reset fix for older dev boards (formerly the "Windows ESP32R0 reset workaround")

Allow separate ethernet & wifi configuration
If only 1/2 of ethernet & WiFi are enabled in config, the other interface is no longer linked into the firmware.
* Fixes bug where enabling Ethernet but not WiFi would fail to compile.
* Also means that enabling WiFi but not Ethernet no longer links some unused ethernet interface functions.
See merge request !525
Partition/SPI/OTA docs & OTA new functionality

* Refactor OTA implementation to perform checks mentioned in API doc
* Add new functions to OTA API: esp_ota_get_running_partition() & esp_ota_get_next_update_partition() functions
* Add spi_flash_cache2phys() & spi_flash_phys2cache() functions to support esp_ota_get_running_partition()

1. indicate adv/scan start complete success or failed
2. controller do limit of adv/scan concurrence, so add some codes to report adv/scan start failed or not.
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
Verify 0xE9 magic byte on first write, verify entire image before
switching.
Enable verification for secure boot signature (was using invalid ifdef
guard)
In the existing tree, after a connected client disconnects the device
will never re-enter the advertising state. Additional clients will not
be able to discover or connect to the device. This patch forces the
device back into the advertising state upon disconnection.
Resolves Pull Request #217https://github.com/espressif/esp-idf/pull/217
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
If using WIFI_INIT_CONFIG_DEFAULT, error message will point out lack
of WiFi. Otherwise linker errors on WiFi symbols should help give a
clue as to what is broken.
Piggy-backs on changes in !420, ref github #230#237
- low level on GPIO12 corresponds to 3.3V output, not 1.8V
- add espefuse.py commands to burn efuses
- add XPD_SDIO_REG to the list of efuses which must be set
Reported on the forum: http://esp32.com/viewtopic.php?f=2&t=849&start=10#p4170
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
Clean up WiFi & Bluetooth config options
* Splits "WiFi" configuration out from ESP32 configuration submenu to its own menu.
* Renames "BT" to "Bluetooth", enabling Bluetooth is now in this option not the ESP32 submenu.
* Also disables compiling/linking of BT stack if Bluetooth is disabled, saves some build time.

examples/10_openssl_server: fixup SSL server with method of specific version
1. add method of any version supporting at OpenSSL and add API in header file
2. change OpenSSL server context method to be method of any version
Fixes http://esp32.com/viewtopic.php?f=14&t=696.
See merge request !369
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
1. add fading functions.
2. clear up ledc.c and ledc.h
3. update api doc.
4. add ledc example
5. edit ledc.rst and add readme for example code.
6. add s_ prefix for static global values.
7. add mutex for fade functions
8. minor changes according to the comments.
1. add method of any version supporting at OpenSSL and add API in header file
2. change OpenSSL server context method to be method of any version
Fixes http://esp32.com/viewtopic.php?f=14&t=696.
2. update example comments and other minor changes
3. rename API: i2c_cmd_link_create/i2c_cmd_link_delete (+4 squashed commits)
Squashed commits:
[2e0ac3e] 1. coding style: add one space after condition key words.
2. modify i2c.h, use gpio_num_t instead of int, improve comments of return values

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.

Add dynamic interrupt allocation mechanism
This adds:
- Dynamic allocation of interrupts. Pass it the features of the interrupt you want, it'll set you up with an int.
- Shared interrupts. Enables multiple peripheral drivers to use the same interrupt.
- Marking what interrupts are fully executable from IRAM; if an int isn't marked like that it will get disabled once flash cache gets disabled.
Also:
- Modifies driver to be in line with these changes
See merge request !254
Fail CI build on warnings
This allows developers to add CFLAGS for -Wno-error=XXX while developing, but before code passes the CI build then it must be warning-free.
See merge request !279
Feature/btdm bluedroid
This branch contain the bluedroid host code.
Currently, Only GAP/GATT SERVER/GATT CLIENT release to users.
Actually, the content of the codes is further more than GAP/GATT and etc.
In this release version, users only need to concern about the APIs which are in "api/include/".
Now, suggestions in comment have been resolved are following:
1. The APIs use callback function. Ivan , Jeroen and me have discussed it. Currently the code will not be changed.
2. The APIs use OPEN/CLOSE. I have ask Ivan, besides bluedroid do this, we will keep the name.
3. Coding style. I have run format.sh to handle the style. And some spell error have been fixed.
4. APIs doxygen. I have clean the warning by doxygen. But bt.rst is still need to be completed.
5. Other comment without resolved face to face that I have to add response in the comment and fix them in the code
6. Fix some incorrect things. See the git log for details.
This 1st version of bluedroid release still have lots of things to do. But it can be done after this merge.
1. Compelete the BLUFI(Bluetooth config wifi connection) documents, security, application protocol and other.
2. Add SPP-LIKE profile.
3. Do more examples codes to cover most of the APIs.
4. Test and fix bug.
Another thing：
1. Do the document of APIs.(xml->bt.rst->html)
(I will do this before merge as Ivan's suggestion)
This is already done. Besides, the union type in doxygen have something error. Ivan will fix it.
See merge request !239
driver: PCNT
1. add PCNT module in periph_ctrl.c/.h
2. add description of PCNT status in pcnt_struct.h
3. add PCNT driver code
4. add PCNT example code.
