Merge tag 'spi-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "This release is almost entirely new drivers, with a couple of small changes in generic code. The biggest individual update is a rename of the existing Microchip driver and the addition of a new driver for the silicon SPI controller in their PolarFire SoCs. The overlap between the soft IP supported by the current driver and this new one is regrettably all in the IP and not in the register interface offered to software. - Add a time offset parameter for offloads, allowing them to be defined in relation to each other. This is useful for IIO type applcations where you trigger an operation then read the result after a delay. - Add a tracepoint for flash exec_ops, bringing the flash support more in line with the debuggability of vanilla SPI. - Support for Airoha EN7523, Arduino MCUs, Aspeed AST2700, Microchip PolarFire SPI controllers, NXP i.MX51 ECSPI target mode, Qualcomm IPQ5414 and IPQ5332, Renesas RZ/T2H, RZ/V2N and RZ/2NH and SpacemiT K1 QuadSPI. There's also a small set of ASoC cleanups that I mistakenly applied to the SPI tree and then put more stuff on top of before it was brought to my attention, sorry about that" * tag 'spi-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (80 commits) spi: microchip-core: Refactor FIFO read and write handlers spi: ch341: fix out-of-bounds memory access in ch341_transfer_one spi: microchip-core: Remove unneeded PM related macro spi: microchip-core: Use SPI_MODE_X_MASK spi: microchip-core: Utilise temporary variable for struct device spi: microchip-core: Replace dead code (-ENOMEM error message) spi: microchip-core: use min() instead of min_t() spi: dt-bindings: airoha: add compatible for EN7523 spi: airoha-snfi: en7523: workaround flash damaging if UART_TXD was short to GND spi: dt-bindings: renesas,rzv2h-rspi: Document RZ/V2N SoC support spi: dt-bindings: renesas,rzv2h-rspi: Document RZ/V2N SoC support spi: microchip: Enable compile-testing for FPGA SPI controllers spi: Fix potential uninitialized variable in probe() spi: rzv2h-rspi: add support for RZ/T2H and RZ/N2H spi: dt-bindings: renesas,rzv2h-rspi: document RZ/T2H and RZ/N2H spi: rzv2h-rspi: add support for loopback mode spi: rzv2h-rspi: add support for variable transfer clock spi: rzv2h-rspi: add support for using PCLK for transfer clock spi: rzv2h-rspi: make transfer clock rate finding chip-specific spi: rzv2h-rspi: avoid recomputing transfer frequency ...
