Hi, please consider applying this patch set. It contains a driver for the audio clock generator on Marvell MMP2 along with the DT bindings. Currently the I2S driver (mmp2-sspa) doesn't have support for DT and is not able to get clocks from this driver. The patch set to address that will be sent separately. Note that the DT binding validation is going to complain about the example in it until the "clk: mmp2: Enable Audio and GPU on MMP2 and MMP3" [1] patch set is merged. Not a big deal I suppose. [1] https://lore.kernel.org/lkml/20200511192517.1206442-1-lkundrak@xxxxx/ This patch set has been tested on an OLPC XO-1.75 laptop, along with a patched mmp-sspa driver and rt5631 codec. Thank you Lubo
