Subject: [V2 0/2] ARM: imx6qdl: remove PLL4_AUDIO_DIV clock

This series removes the unsupported PLL4_AUDIO_DIV clock which appeared
in early versions of the i.MX6DQ reference manual, but doesn't function
as described in the current clock driver (i.e., it's a divide-by-1).

Since the clock node is also used to control the topology of the clock
tree, the PLL4_POST_DIV node is used to control parenting of downstream
SSI, CKO1, and ESAI/ASRC/SPDIF peripherals.

The first patch removes the clock, and the second updates several
device tree files to use PLL4_POST_DIV to select proper parents.
