From e4d20e76658f7ffad08bf3abe724a923a16bdea6 Mon Sep 17 00:00:00 2001 From: Anssi Hannula Date: Mon, 16 Jun 2014 02:39:45 +0300 Subject: [PATCH] ARM: dts: imx6: remove non-working spdif rxtx4 and rxtx6 clocks The S/PDIF rxtx4 and rxtx6 clock inputs are "ESAI_HCKT" and "MLB clock", respectively, according to the SoC documentation, and they are currently mapped to clocks "esai" and "mlb". However, they do not seem to actually work correctly. Testing on a Cubox-i system with fsl_spdif driver forced to select one of those as input will result in I/O errors on audio playback, which I believe means missing clock signal. Possibly the "ESAI_HCKT" and "MLB clock" refer to some other clocks related to ESAI and MLB, or we are missing something else. Since audio playback will not work if fsl_spdif selects these clocks (which happens rarely), set the inputs do dummy clocks, at least for now.
