This series adds device tree nodes for Multi Channel Serial Peripheral
Interface (MCSPI) on J721E, J7200, J721S2 and J784S4 platforms. All the
MCSPI instances are disabled by default and can be enabled through overlays
as required, the changes were tested using spidev loopback test for all
instances and the data verified only for main_spi4 which is connected
internally as slave to mcu_spi2 for all existing J7 devices.

Why split the patches per bus? why not club the patches at SoC level?

I split them initially since the changes were in two different files, I have
combined the changes at SoC level and send a V2,
