This patch enables the Microchip's FPGA QSPI and Polarfire SoC QSPI controller support.
Tested spi-nand (W25N01GV) and spi-nor (MT25QL256A) on Microchip's ICICLE kit. tested using both FPGA QSPI and Polarfie SoC QSPI.
changes in v4 ------------- 1. Removed microchip,mpfs-qspi compatible from the driver 2. Changed platform_get_irq() return value check from <=0 to <0 3. Fixed dt_binding_check warning by installing latest yamllint
changes in v3 ------------ 1. Added dev_err_probe() at places like probe failures 2. Split the dt-bindings one for adding coreqspi compatible and other one to add coreqspi as fallback to mpfs-qspi.
changes in v2 ------------ 1. Replaced spi_alloc_master() with devm_spi_alloc_master() 2. Used dev_err_probe() when devm_spi_alloc_master() fails. 3. Added shared IRQ flag in the interrupt registration. 4. Updated the dt_bindings so that there is a differentiation between FPGA QSPI IP core and hard QSPI IP core.
