b8dc48ab18 gpio/driver: Sped the gpio_intr_service ISR up by 1.5 uSeconds (+-50% faster).
Removed as much branching (if statements) from the
gpio_intr_service ISR, as possible and split the while loop into
two. Also forced writing the two status*_w1tc variables only once,
instead of every time after calling the external function hooks.

The measurements below, was done using the following tools:

Toolchain version: crosstool-ng-1.22.0-80-g6c4433a
Compiler version: 5.2.0

Here follows a comparison of the gpio_intr_service ISR's
execution time, using a DS1054 oscilloscope. All the time spent
calling external functions, via the function pointers
gpio_isr_func[gpio_num].fn, were disregarded.

With OPTIMIZATION_FLAGS = -Og, 1.34 uSeconds faster:

3.22 uSec (with this patch)
4.56 uSec (with commit 71c90ac4)

100 - (100 * 4.56 / 3.22) = 42% faster

With OPTIMIZATION_FLAGS = -Os, 1.65 uSeconds faster:

2.89 uSec (with this patch)
4.54 uSec (with commit 71c90ac4)

100 - (100 * 4.54 / 2.89) = 57% faster

f7749e18a8 gpio: Bitmask overflow fix in gpio_reset_pin
For pins 32 and up the BIT(nr) macro used here overflowed,
causing undetermined GPIO pins to be reset.
Example: freeing SPI device/bus where CS is on pin 33
caused debug UART to cease communication, TXD0 was
disabled.

Fixed as BIT64(nr) macro, to be used elsewhere as needed.
For example in definitions like GPIO_SEL_32..GPIO_SEL_39.

4297c337f9 esp32: Add IO_MUX_GPIOxx register names to match iomux names used in TRM
The TRM describes IOMUX registers are IO_MUX_x_REG for x in GPIO0-39.

Until now ESP-IDF describes them as PERIPHS_IO_MUX_(pinname)_U

This commit adds additional IOMUX register names which match the ones used in the TRM.

ac412feb69 gpio: Attach gpio intr to the isr_server on the right core.
Make sure GPIO interrupts get attached to the core that
the ISR service routine is running on, otherwise they
don't arrive.

ade7ee2092 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. improve gpio.rst
4. add readme for gpio example

3b854fe46a deep sleep: implement wake up using ULP, EXT0, EXT1 sources
This adds the following APIs to enable various wakeup sources:
- esp_deep_sleep_enable_timer_wakeup
- esp_deep_sleep_enable_ulp_wakeup
- esp_deep_sleep_enable_ext0_wakeup
- esp_deep_sleep_enable_ext1_wakeup

And an API to start deep sleep:
- esp_deep_sleep_start

1c60a0450e Merge branch 'bugfix/driver_cleanup_log' into 'master'
drivers: remove file paths from log statements

Function name and error string are usually sufficient to find the place which has triggered an error. 

`__FILE__` macro generates a string which has absolute file name (with our build system), which add many long strings to the program binary.

Also change log tags to lower case to match style used elsewhere.

Fixes https://github.com/espressif/esp-idf/issues/126

b1db2721dc driver: add rtc module and bugfix gpio32 gpio33
feature(rtc_module):add rtc module

1. add rtc io control API (pull,output and input)
2. add touch pad API (touch pad read and interrupt)
3. add adc1 API (the max width is 12 Bits and support attenuation)
4. add hall sensor API (support hall sensor read )
5. add dac API (the width is 8 Bits)

bugfix(gpio):gpio32 and gpio33 can not output and input

the gpio32 and gpio33 is initialize by librtc.a,and gpio_config not initialize the gpio as
digital gpio.they can not output and input,when users use gpio32 or gpio33.And there are some problems
about others driver ,when they use gpio32 or gpio33 as  matrix.

2. Modify some API return value.
3. Add ledc_set_pin() for LEDC
4. Modify typo in uart.h

Questions: In uart driver ISR handler, I used xxxFromISR , like xSemaphoreGiveFromISR, do those FromISR functions need to be put in IRAM?
