| Message-ID | <uqSJr-7os-1@gated-at.bofh.it> |
Add devicetree binding support for rt5514 spi dsp codec. Also update rt5514 i2c dt-binding's compatible to distinguish it from rt5514 spi. Signed-off-by: Jeffy Chen <jeffy.chen@rock-chips.com> --- Changes in v10: Put rt5514-i2c doc & rt5514-spi doc together. Changes in v9: Address comments from Brian.
