It is designed to be paired with the MediaTek MT8186 SoC. It has 9 buck regulators and 29 LDO regulators, not counting ones that feed internally and basically have no controls. The regulators are named after their intended usage for the SoC and system design, thus not named generically as ldoX or dcdcX, but as vcn33 or vgpu. Add a binding document describing all the regulators and their supplies. Signed-off-by: Zhiyong Tao [wens@chromium.org: major rework and added commit message] Signed-off-by: Chen-Yu Tsai --- Changes since Zhiyong's last version (v4) [1]: - simplified regulator names - added descriptions to regulators - removed bogus regulators (*_sshub) - merged vcn33-wifi and vcn33-bt as vcn33 - added missing regulators (vm18, vmddr, vsram-core) - cut down examples to a handful of cases and made them complete - expanded commit message a lot [1] https://lore.kernel.org/linux-arm-kernel/20220823123745.14061-1-zhiyong.tao@mediatek.com/ .../regulator/mediatek,mt6366-regulator.yaml | 154 ++++++++++++++++++ 1 file changed, 154 insertions(+) create mode 100644 Documentation/devicetree/bindings/regulator/mediatek,mt6366-regulator.yaml diff --git a/Documentation/devicetree/bindings/regulator/mediatek,mt6366-regulator.yaml b/Documentation/devicetree/bindings/regulator/mediatek,mt6366-regulator.yaml new file mode 100644 index 000000000000..715c6ffcb3ab --- /dev/null +++ b/Documentation/devicetree/bindings/regulator/mediatek,mt6366-regulator.yaml @@ -0,0 +1,154 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/regulator/mediatek,mt6366-regulator.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: MT6366 Regulator from MediaTek Integrated + +maintainers: + - Zhiyong Tao + +description: | + Regulator part of the MT6366 PMIC.
