b35d9002f3 driver(I2S): Fix i2s_comm_format_t configuration parameter does not match the TRM bug.
When I2S `i2s_comm_format_t` is set to `I2S_COMM_FORMAT_I2S_MSB`, the data should launch at first BCK. But not in fact, this MR fixed this issue.

For compatibility, several nwe parameters have been added, and the old parameters will be removed in the future.

9d39881981 i2s: add support apll clock
using apll_param to setup APLL

new apll calculation method, much faster

validate freq calculation

Ensure that the i2s frequency is greater than the hardware limit

Add description of how to calculate apll clock, support apll for other 16-bits audio, check rev0 chip

correct space

7db85a386a Merge branch 'bugfix/i2s_driver' into 'master'
I2S driver - fixed support for 24 and 32-bits, fixed tx/rx at the same time

- Modify sample can test with 24, 32-bits audio
- Add i2s sample README
- simply i2s_push function
- change sample rates, bits per sample, channel on fly

See merge request !483

fc1ee2666a I2S: fixed support for 24 and 32-bits, fixed tx/rx at the same time and others in log:
Add support 24, 32 bits

@jxmao optimize i2s_zero_buffer

@jxmao correct config support slave mode

@jxmao correct setup pin support tx/rx at the same time

Enhance pin power

@jxmao add dynamic change number of channels

remove nvs_init

remove start log and enhance power pin setup

using enum for i2s_channel and i2s_bits_per_sample, return ESP_ERR_INVALID_ARG when check params

validate i2s_bits_per_sample and channel

check tx & rx buffer before fill zero

remove checking channel as @jxmao suggest

limit dma buffer

modify i2s pin back to gpio mux before configure gpio matrix, resolve github issue #512

Add support 24, 32 bits

reduce push function

Modify sample can test with 24, 32-bits

Add i2s sample README

Fixed i2s_set_clk got reset sometime

can changes bit-wide while running

Fix sample rate calculation for DAC mode from @jeroen

modify example can change bits per sample every 5 seconds

cleanup

add comment for bytes_per_sample

update as @angus suggestions

Add i2s_set_clk api

I2S driver bug fixed as following log:

@jxmao optimize i2s_zero_buffer

@jxmao correct config support slave mode

@jxmao correct setup pin support tx/rx at the same time

Enhance pin power

@jxmao add dynamic change number of channels

remove nvs_init

remove start log and enhance power pin setup

using enum for i2s_channel and i2s_bits_per_sample, return ESP_ERR_INVALID_ARG when check params

check tx & rx buffer before fill zero

remove checking channel as @jxmao suggest

limit dma buffer

modify i2s pin back to gpio mux before configure gpio matrix, resolve github issue #512

limit dma buffer to 4092

change gpio_matrix_*_check to inline function, remove some comments and rename test_i2s function to setup_triangle_sine_waves

821c70f5d7 examples: Standardise naming of files, symbols, etc. in examples
* Use "example" in all example function & variable names,
  ie use i2c_example_xxx instead of i2c_xxx for example functions.
  Closes #198 https://github.com/espressif/esp-idf/issues/198
* Mark example functions, etc. static
* Replace uses of "test" & "demo" with "example"
* Split the UART example into two
* Rename "main" example files to end with "_main.c" for disambiguation
