[alsa-devel] [PATCH v5 0/4] Add support for es8388 and hdmi audio on the rock2

[Romain Perier]

This set of patches adds a machine driver for rk3288-based boards that have
the built-in HDMI audio and a generic analog output. It also adds slave mode
to the es8328 driver that currently only supported the master mode. Then, it
adds the required DT definitions to link rockchip-i2s to the es8388 analog
output and to hdmi audio.

This work is based on the initial work that was done by Sjoerd Simons
<sjoerd.simons at collabora.co.uk> with some improvements, changes and more
commits.

Changes in v5:
 - Fixed coding style issue in patch 2/4 (the switch case).
 - Moved the code for the master mode and the slave mode into the switch case for patch 2/4
 - Fixed error handling for patch 3/4
Changes in v4:
 - Add support for multi codecs in the asoc machine driver, so the driver
   matches the hw architecture (analog and hdmi audio are connected on
   the same i2s line)
 - Renamed the driver to rk3288-hdmi-analog.c and changed its
   documentation
 - Add built-in support for hdmi audio in this driver
 - Add support for the property 'rockchip,routing'

Changes in v3:
 - Cosmetic changes in rockchip_es8388.c
 - Added missing email to MODULE_AUTHOR in rockchip_es8388.c
Changes in v2:
 - Fixed wrong use of the data structure i2c_device_id
 - Fixed wrong dependencies for SND_SOC_ROCKCHIP_ES8388
