Add combined sequence mode supported by Tegra QSPI controller. For commands which contain cmd, addr, data parts to it, controller can accept all 3 transfers at once and avoid interrupt for each transfer. This would improve read & write performance. Signed-off-by:

Convert the Samsung SoC (S3C24xx, S3C64xx, S5Pv210, Exynos) SPI controller bindings to DT schema format. The conversion also drops requirement from providing controller-data and its data for each of SPI peripheral device nodes. The dtschema cannot express this and the requirement is being relaxed in the driver now. Signed-off-by:

The minimum array length defaults to the same size as the maximum. For 'mediatek,pad-select', the example has a length of 2 and in-tree .dts files have a length of 1, but the schema says the length must be 4. There's currently no warning in the example because the schema fixups are not handling this case correctly. Signed-off-by:

Commit d40f0b6f instroduced last_cs_enable to avoid setting chipselect if it's not necessary, but it also introduces a bug. The chipselect may not be set correctly on multi-device SPI busses. The reason is that we can't judge the chipselect by bool last_cs_enable, since chipselect may be modified after other devices were accessed. So we should record the specific state of chipselect in case of confusion. Signed-off-by:
