"Simple" in this context means that they allow to directly control reset lines by setting and clearing bits in a single register or in a contiguous register range that is exclusive to the reset controller. Parts of the sunxi driver and the socfpga, stm32, and zx2967 drivers are merged into a single reset-simple driver. The sunxi driver is kept around to register the early reset controllers, but it reuses the exported reset_simple_ops. Changes since v3 [1]: - Split the first patch into reset-simple addition (now patch 1) and reset-sunxi conversion (now patch 2). I'd really like to get an ok from the sunxi maintainers for the second one. - Rename reset_simple_set to reset_simple_update, as that function is used to both set and clear the control bit. - Changed reset-simple to only ever warn about the missing "altr,modrst-offset" property on socfpga, in case another compatible will use a non-zero default reg_offset in the future. - Dropped patch 5 ("reset: simple: read back to make sure changes are applied"). Its use is purely theoretical, and this series is about unifying the existing drivers.
