It has a different set of regulators. Specifically, it lacks the camera related VCAM* LDOs and VLDO28, but has additional VM18, VMDDR, and VSRAM_CORE LDOs. The PMICs contain a chip ID register that can be used to detect which exact model is preset, so it is possible to share a common base compatible string. Add a separate compatible for the MT6366 PMIC, with a fallback to the MT6358 PMIC.

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 v1: - Replaced underscores in supply names to hyphens - Merged with MT6358 regulator binding - Added MT6358 fallback compatible to MT6366 regulator 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,mt6358-regulator.yaml | 227 +++++++++++++----- 1 file changed, 168 insertions(+), 59 deletions(-) diff --git a/Documentation/devicetree/bindings/regulator/mediatek,mt6358-regulator.yaml b/Documentation/devicetree/bindings/regulator/mediatek,mt6358-regulator.yaml index 82328fe17680..b350181f33ff 100644 --- a/Documentation/devicetree/bindings/regulator/mediatek,mt6358-regulator.yaml +++ b/Documentation/devicetree/bindings/regulator/mediatek,mt6358-regulator.yaml @@ -16,14 +16,18 @@ description: | properties: compatible: -

This better matches the PMIC pin names. Remaining underscores in names are also replaced with hyphens. Drop the type prefixes and replace remaining underscores to match the MT6366 binding.

In reality there are differences. A few regulators have different ranges, or were renamed and repurposed, or removed altogether. Add the 3 regulators that were missing from the original submission. These are added for completeness. VSRAM_CORE is not used in existing projects. VM18 and VMDDR feed DRAM related consumers, and are not used in-kernel.
