Subject: Applied "dt-bindings: regulator: document stpmic1 pmic regulators" to the regulator tree
Date: Mon, 8 Oct 2018 19:55:02 +0100 (BST) [thread overview]
Message-ID: <20181008185502.6BDAC440078@finisterre.ee.mobilebroadband> (raw)
In-Reply-To:
The patch
dt-bindings: regulator: document stpmic1 pmic regulators
has been applied to the regulator tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

Subject: [PATCH] dt-bindings: regulator: document stpmic1 pmic regulators
The STPMIC1 regulators supply power to the application processor as well as
to the external system peripherals such as DDR, Flash memories and system
devices.

+STMicroelectronics STPMIC1 Voltage regulators
+
+Regulator Nodes are optional depending on needs.
+
+Available Regulators in STPMIC1 device are:
+ - buck1 for Buck BUCK1
+ - buck2 for Buck BUCK2
+ - buck3 for Buck BUCK3
+ - buck4 for Buck BUCK4
+ - ldo1 for LDO LDO1
+ - ldo2 for LDO LDO2
+ - ldo3 for LDO LDO3
+ - ldo4 for LDO LDO4
+ - ldo5 for LDO LDO5
+ - ldo6 for LDO LDO6
+ - vref_ddr for LDO Vref DDR
+ - boost for Buck BOOST
+ - pwr_sw1 for VBUS_OTG switch
+ - pwr_sw2 for SW_OUT switch
+
+Switches are fixed voltage regulators with only enable/disable capability.
+
+Optional properties:
+- st,mask-reset: mask reset for this regulator: the regulator configuration
+ is maintained during pmic reset.
+- regulator-pull-down: enable high pull down
+ if not specified light pull down is used
+- regulator-over-current-protection:
+ if set, all regulators are switched off in case of over-current detection
+ on this regulator,
+ if not set, the driver only sends an over-current event.
+- interrupt-parent: phandle to the parent interrupt controller
+- interrupts: index of current limit detection interrupt
+- <regulator>-supply: phandle to the parent supply/regulator node
+ each regulator supply can be described except vref_ddr.
+
+Example:
+regulators {
+ compatible = "st,stpmic1-regulators";
+
+ ldo6-supply = <&v3v3>;
+
+ vdd_core: buck1 {
+ regulator-name = "vdd_core";
+ interrupts = <IT_CURLIM_BUCK1 0>;
+ interrupt-parent = <&pmic>;
+ st,mask-reset;
+ regulator-pull-down;
+ regulator-min-microvolt = <700000>;
+ regulator-max-microvolt = <1200000>;
+ };
+
+ v3v3: buck4 {
+ regulator-name = "v3v3";
+ interrupts = <IT_CURLIM_BUCK4 0>;
+ interrupt-parent = <&mypmic>;
+
+ regulator-min-microvolt = <3300000>;
+ regulator-max-microvolt = <3300000>;
+ };
+
+ v1v8: ldo6 {
+ regulator-name = "v1v8";
+ regulator-min-microvolt = <1800000>;
+ regulator-max-microvolt = <1800000>;
+ regulator-over-current-protection;
+ };
+};
