ARM: dts: socfpga: change qspi to "intel,socfpga-qspi"
Because of commit 9cb2ff111712 ("spi: cadence-quadspi: Disable Auto-HW polling"), which does a write to the CQSPI_REG_WR_COMPLETION_CTRL register regardless of any condition. Well, the Cadence QuadSPI controller on Intel's SoCFPGA platforms does not implement the CQSPI_REG_WR_COMPLETION_CTRL register, thus a write to this register results in a crash! So starting with v5.16, I introduced the patch 98d948eb833 ("spi: cadence-quadspi: fix write completion support"), which adds the dts compatible "intel,socfpga-qspi" that is specific for versions that doesn't have the CQSPI_REG_WR_COMPLETION_CTRL register implemented. Signed-off-by: Dinh Nguyen <dinguyen@kernel.org> --- v3: revert back to "intel,socfpga-qspi" v2: use both "cdns,qspi-nor" and "cdns,qspi-nor-0010"
