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. V1->V2: * Address Nishanth's feedback, combine main, mcu domain MCSPI node addition changes to single commit per SoC.
