Subject[PATCH v2 0/5] Unify simple reset drivers
Date
Hi,

from time to time people notice that we are slowly accumulating reset drivers
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.

I had previously suggested to add common reset ops for them [1], and Andre
advised to combine them into a single platform driver instead. This series
does that. It should allow to replace the socfpga, stm32, and zx2967 drivers
entirely.
The SoCFPGA device tree quirk parsing is now contained in reset-simple.c.
The sunxi driver is kept around to register the early reset controllers,
but it reuses the exported reset_simple_ops.

regards
Philipp

Philipp Zabel (5):
reset: add reset-simple to unify socfpga, stm32, sunxi, and zx2967
reset: socfpga: use the reset-simple driver
reset: stm32: use the reset-simple driver
reset: zx2967: use the reset-simple driver
reset: simple: read back to make sure changes are applied
