The reparenting of I2S bus clock is not done anymore, but is left to use the default value set in bootloader. With default setup (XXTI as the parent), I have tested wave files with various sample rates on Snow. The missing part right now is setting XCLKOUT (mclk for the audio codec) properly. In internal tree, I have directly programmed the XCLKOUT register (we don't have a clock for it as this register is not part of clock domain). I am now working on preparing a clock provider for XCLKOUT. >> > Please do also pay attention to the CC lists when posting patches, this >> > seems to have been sent to a fairly random selection of people and >> > lists. > >> Okay, I will update the CC list as per get_maintainer script during >> next revision. > > Please think about the results when doing that - get_maintainers is very > useful but it does generate false positives and miss people. > I will do my best to add relevant people in the discussion. >> >> + ret = snd_soc_dai_set_clkdiv(cpu_dai, SAMSUNG_I2S_DIV_BCLK, bfs); >> >> + if (ret < 0) >> >> + return ret; > >> > Set this stuff up on probe.
