[PATCH 1/2] ARM: dts: imx6ul: Specify the SAI index

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

Introduce the "sai-index" property to indicate the index of the SAI port.

This is useful for enabling the SAI_MCLK output as we need to write
to bits 19, 20 and 21 of register GPR1 for enabling SAI1, SAI2 and SAI3,
respectively.

[PATCH 2/2] ARM: dts: imx6ul-14x14-evk: Enable SAI2_MCLK

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

Pass the "gpr" and "fsl,sai-enable-mclk" to the sai2 node, so that
we can enable the SAI2_MCLK.

Is the property documented or supported by kernel?
