From 531ee1f4ea7fb5634cb79824e6df6be83596a054 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Sat, 17 Oct 2015 21:05:21 -0700 Subject: ARM: dts: vf610: fix clock definition for SAI2 So far, only the bus clock has been assigned, but in reality the SAI IP has for clock inputs. The driver has been updated to make use of the additional clock inputs by c3ecef21c3f2 ("ASoC: fsl_sai: add sai master mode support"). Due to a bug in the clock tree, the audio clock has been enabled none the less by the specified bus clock (see "ARM: imx: clk-vf610: fix SAI clock tree"), which made master mode even without the proper clock assigned working. This patch completes the clock definition for SAI2. On Vybrid, only two MCLK out of the four options are available (the first being the bus clock itself). See chapter 8.10.1.2.3 of the Vybrid Reference manual ("SAI transmitter and receiver options for MCLK selection"). Note: The audio clocks are only required in master mode.
