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.
