You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark
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.
