Hi,
This series introduces common reset ops for simple reset controllers. "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.
The first patch depends on [1] or commit 726cc791c9b9 ("reset: sunxi: fix number of reset lines") in linux-next. On linux-next, the second patch will trivially conflict with commit 7799167b7a14 ("regulator: Convert to using %pOF instead of full_name").
Changes since v2 [2]: - Use of_device_get_match_data instead of of_match_device, add kerneldoc comment for struct reset_simple_devdata and struct reset_simple_data, suggested by Chen-Yu. - Add reg_offset and nr_reset override to struct reset_simple_devdata, instead of special casing socfpga, always check "altr,modrst-offset" device tree property if a default reg_offset is set, based on Alexandru's advice. - Rename "*inverted" properties to "*active_low".
