[PATCH v2 0/2] DRA7x: Increase QSPI frequency to 64MHz

[Vignesh R]

This patch series increases QSPI bus frequency to 64MHz and switch to
SPI mode 0 in order to increase read/write throughput.
First patch removes QSPI pinmux from DT as pinmux can only be done in
U-Boot(see patch commit message for more info). Second patch does the
dts changes to support 64MHz mode 0 operation.


Tested on DRA74 and DRA72 EVM with U-Boot 2016.05-rc1.
