In order to access the protected IO power domain registers, a valid unlock sequence must be performed by writing the required keys to the AIB Secure Access Register (ASAR). The ASAR register resides within the APBC register address space. A corresponding syscon property is added to allow the pinctrl driver to access this register. Signed-off-by: Troy Mitchell <troy.mitchell@linux.spacemit.com> --- Changelog in v2: - add `spacemmit` prefix in the subject - remove offset in syscon property - remove `spacemit,apbc` property in required - Link to v1: https://lore.kernel.org/spacemit/20260108042753-GYA2796@gentoo.org/T/#m2ab46cd63cbb1b110eb317ee5b9d540d39cbd82b (local) --- Documentation/devicetree/bindings/pinctrl/spacemit,k1-pinctrl.yaml | 5 +++++ 1 file changed, 5 insertions(+)
