Add support for the Everest-semi ES8311 codec. Everest-semi ES8311 codec is a low-power mono audio codec with I2S audio interface and I2C control. Supported features: * Both master and slave mode. Master clock is optional in slave mode. * Sample rates from 8KHz to 96KHz. * Sample formats: S16_LE, S18_3LE, S20_3LE, S24_3LE, S24_LE and S32_LE. * I2S formats: I2S, LEFT_J, DSP_A, DSP_B. * BCLK and FSYNC clocks inversion. * Component suspend/resume. * ADC, PGA, DAC controls. * ADC DSP controls: volume, fade (ramp rate), ALC, automute, HPF, EQ. * DAC DSP controls: volume, fade (ramp rate), DRC, EQ. * DAPM routes: capture path with input source selection (differential MIC/DMIC) and AIF channel source selection; playback path with DAC channel source selection. Limitations: * Support only for master clocks with a ratio of ADC (or DAC) clock to LRCLK equal to 256. This to keep the default ADC and DAC oversampling and ADC scale settings. Anyway all 8-96KHz sample rates are supported when the ratio of MCLK to sample rate is 32, 64, 128, 256, 384 or 512 (upper limit due to max MCLK freq of 49.2MHz). * Coefficients for ADC HPF and ADC/DAC EQ not supported. * Digital mic supported but not tested. * S18_3LE, S20_3LE and S24_3LE formats supported but not tested.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
