This RFC series adds a facility for syscon devices to control a reset line when probed; we have instances of simple register-only syscon resources that need deassertion of a reset line for the register set to be accessible. Rather than requiring a specific driver to implement this, it'd be nice to use the generic syscon device and the generic resets linkage to do so. Any comments/queries/etc are most welcome. Cheers, Jeremy --- v2: * do reset control in the early of_syscon_register() path, rather than the platform device init, which isn't used. * consequently, add regmap infrastructure to attach a reset controller, in a similar way to attaching clocks Jeremy Kerr (3): dt-bindings: mfd/syscon: Add resets property regmap: mmio: allow reset control in a MMIO regmap mfd: syscon: allow reset control for syscon devices .../devicetree/bindings/mfd/syscon.yaml | 3 +++ drivers/base/regmap/regmap-mmio.c | 22 +++++++++++++++ drivers/mfd/syscon.c | 27 ++++++++++++++----- include/linux/regmap.h | 3 +++ 4 files changed, 49 insertions(+), 6 deletions(-) -- 2.35.1
