This change is scattered through a There are SoCs that have multiple instances of the SPI IP, and they configure them with different FIFO depths. See "samsung,exynosautov9-spi" for example: SPI0, SPI1, and SPI6 are configured by the SoC to use 256 bytes FIFO depths, while all the other 8 SPI instances use 64 bytes FIFOs. I tried to explain the entire logic of the series in another reply, see it here: https://lore.kernel.org/linux-arm-kernel/40ba9481-4aea-4a72-87bd-c2db319be069@xxxxxxxxxx/T/#u > very large series which does multiple things so it's a bit difficult to > follow what's going on here. Sorry, I was afraid that this might happen. I agree, I'll split tomorrow this patch set in 3 smaller sets: 1/ dumb cleaning patches 2/ heavy lifting cleaning patches 3/ gs101 addition
