For the same reason, the CLK_C clock line and I2C configuration (similar to the ak4613, on the same interface) are added into the common file. Signed-off-by: Alexander Riesen Reviewed-by: Geert Uytterhoeven --- v2: Also add ssi4_ctrl pin group in the sound pins. The pins are responsible for SCK4 (sample clock) WS4 and (word boundary input), and are required for SSI audio input over I2S. Suggested-by: Geert Uytterhoeven The adv748x shall provide its own implementation of the output clock (MCLK), connected to the audio_clk_c line of the R-Car SoC. If the frequency of the ADV748x MCLK were fixed, the clock implementation were not necessary, but it does not seem so: the MCLK depends on the value in a speed multiplier register and the input sample rate (48kHz). Suggested-by: Geert Uytterhoeven Remove audio clock C from the clocks of adv7482. The clocks property of the video-receiver node lists the input clocks of the device, which is quite the opposite from the original intention: the adv7482 on Salvator X boards is a provide of the MCLK clock for I2S audio output. Suggested-by: Geert Uytterhoeven Remove old definition of &sound_card.dais and reduce size of changes in the Salvator-X specific device tree source. Declare video-receiver a clock producer, as the adv748x driver implements the master clock used I2S audio output. Suggested-by: Geert Uytterhoeven The driver provides only MCLK clock, not the SCLK and LRCLK, which are part of the I2S protocol.
