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@collabora.co.uk with some improvements, changes and more commits.
Changes in v7: - Added patch 2/4 - No longer select ES8328_I2C for RK3288_HDMI_ANALOG - Fixed DT regulator names in the DT for the Rock2 - Splitted pins for the headphone in the DT for the Rock2 Changes in v6: - Fixed bad error handling for gpio in rk3288_analog_hdmi.c - Removed message duplication in rk_hw_params(), in rk3288_analog_hdmi.c - Removed patch 1/4 (from the previous series), as it has been merged 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
