* [PATCH] ARM: DTS: am57xx-beagle-x15: Select SYS_CLK2 for audio clocks @ 2016-02-09 11:46 Peter Ujfalusi [not found] ` <1455018417-2608-1-git-send-email-peter.ujfalusi-l0cyMroinI0@public.gmane.org> 0 siblings, 1 reply; 2+ messages in thread From: Peter Ujfalusi @ 2016-02-09 11:46 UTC (permalink / raw) To: tony; +Cc: linux-omap, devicetree, linux-arm-kernel, linux-kernel, robh+dt, nm The tlv320aic3104 codec's master clock is coming from the SoC's CLKOUT2. Select the SYS_CLK2 (via divider) as parent clock for CLKOUT2 and select the same clock (SYS_CLK2) for McASP3 AHCLKX clock as well. SYS_CLK2 is sourced from an external oscillator running 22.5792MHz and it is coming in to the SoC via the X1_OSC1.
