apalis/colibri t30: fix record/playback for sgtl5000 codectegra-nexttegra
Backported commit f997df18c0e4c988de49e984329cefdf6e13ed86 According to the manual [1], SYS_MCLK should base on SYS_FS, not on sample rate. Calculating SYS_MCLK using sample rate only prevents playing/recording samples with rate < 16 kHz: --------------------------------------------------------------- root@apalis-t30:~# aplay test-8k-sample.wav Playing WAVE 'test-8k-sample.wav' : Signed 16 bit [...] tegra-snd-apalis-tk1-sgtl5000 tegra-snd-apalis-tk1-sgtl5000.0: ASoC: machine hw_params failed: -22 Little Endian, Rate 8000 Hz, Stereo aplay: set_params:1403: Unable to install hw params: ... --------------------------------------------------------------- Using the helper from sgtl5000.h fixes this issue. To keep determination of sys_fs solid, use a helper in device driver. [1] https://www.nxp.com/docs/en/data-sheet/SGTL5000.pdf Signed-off-by: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>
