Subject: [PATCH 1/3] ARM: dts: imx: Add mclk0 clock for SAI
From: Shengjiu Wang <shengjiu.wang@....com>
Audio MCLK source option is selected with a 4:1 MUX
controller using MCLK Select bits in SAI xCR2 register.
On imx6/7 mclk0 and mclk1 always point to the same clock
source. Anyhow, this is no longer true for imx8.
For this reason, we need to add mclk0 and handle it
in a generic way in SAI driver.
