[v3,0/4] Add support for Microchip QSPI controller

Message

Naga Sureshkumar Relli Aug. 5, 2022, 5:30 a.m. UTC

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 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.

    controllers

@Valentina could you test this version please?

Thanks,
