Subject: [PATCH v3 5/5] regulator: rk808: Add RK816 support
Date: Sat, 23 Mar 2024 14:28:03 +0100 [thread overview]
Message-ID: <20240323132757.141861-12-knaerzche@gmail.com> (raw)
In-Reply-To: <20240323132757.141861-2-knaerzche@gmail.com>
Add support for rk816 to the existing rk808 regulator driver.
The infrastructure of the driver can be re-used as is. A peculiarity for
this version is, that BUCK1/BUCK2 have a (common) bit which needs to
toggled after a voltage change to confirm the change. Regulator regmap
takes care of that by defining a apply_bit and apply_reg for those
regulators.

changes since v1:
- align regulator's .name and .of_match with updated binding
changes since v2:
- align regulator's .name and .of_match with updated binding
(dropped "-regulator" prefix)

Subject: [PATCH v3 5/5] regulator: rk808: Add RK816 support
Date: Sat, 23 Mar 2024 14:28:03 +0100 [thread overview]
Message-ID: <20240323132757.141861-12-knaerzche@gmail.com> (raw)
In-Reply-To: <20240323132757.141861-2-knaerzche@gmail.com>
Add support for rk816 to the existing rk808 regulator driver.
The infrastructure of the driver can be re-used as is. A peculiarity for
this version is, that BUCK1/BUCK2 have a (common) bit which needs to
toggled after a voltage change to confirm the change. Regulator regmap
takes care of that by defining a apply_bit and apply_reg for those
regulators.

changes since v1:
- align regulator's .name and .of_match with updated binding
changes since v2:
- align regulator's .name and .of_match with updated binding
(dropped "-regulator" prefix)
