Convert the non-SMD Regulators bindings to dt-schema, the old text based bindings will be deleted later since the RPM bindings are not yet converted. Signed-off-by: Neil Armstrong <neil.armstrong@xxxxxxxxxx> Reviewed-by: Rob Herring <robh@xxxxxxxxxx> --- This is a second round of bindings & DT fixes for the MDM9615 platform. This second round focuses on less trivial changes like pinctrl & regulators bindings, the remaining work will mainly be fixing the qcom,kpss-timer/qcom,msm-timer situation and add bindings for qcom,lcc-mdm9615, qcom,kpss-gcc & swir,mangoh-iotport-spi. Dependencies: None --- Changes in v6: - Fixed ref error on patch 1 - Dropped applied patch 2 - Link to v5: https://lore.kernel.org/r/20221005-mdm9615-pinctrl-yaml-v5-0-910019fb8b9b@xxxxxxxxxx Changes in v5: - Fixed bindings invalid id after rename - Fixed invalid ref path to qcom,rpm-regulator.yaml from qcom,rpm.yaml bindings - Link to v4: https://lore.kernel.org/r/20221005-mdm9615-pinctrl-yaml-v4-0-463523919c19@xxxxxxxxxx Changes in v4: - Removed applied patches - Removed "-ipc" from bindings file name and removed IPC from title & description - Added the review tags from v3 after file renaming & title/description change, after Lee's acceptation - Link to v3: https://lore.kernel.org/r/20221005-mdm9615-pinctrl-yaml-v3-0-e5e045644971@xxxxxxxxxx Changes in v3: - Path 1: Removed from serie because applied - Path 2: None - Path 3: Added reviewed-by tag - Path 4: Fixed dt-schema title and added unevaluatedProperties - Path 5: Various schema fixes, uses same naming as other dt-schema for qcom regulators - New patch added changing regulators names of msm8660 to conform to bindings - Link to v2: https://lore.kernel.org/r/20221005-mdm9615-pinctrl-yaml-v2-0-639fe67a04be@xxxxxxxxxx Changes in v2: - Rebased on v6.1-rc1 - Patch 1: Fixed bindings and aligned with Krysztof's series - Patch 2: Rewrote patch title and added reviewed-by tag - Patch 3: Added reviewed-by tag - Patch 4: Moved to end, added support for (regulators|-regulators) sudnode - Patch 5: Fixed schema description and added missing unevaluatedProperties in patternProperties - Patch 6: Dropped & squashed with patch 4 - Link to v1: https://lore.kernel.org/r/20221005-mdm9615-pinctrl-yaml-v1-0-0cbc006e2a30@xxxxxxxxxx --- .../bindings/regulator/qcom,rpm-regulator.yaml | 128 +++++++++++++++++++++ 1 file changed, 128 insertions(+) diff --git a/Documentation/devicetree/bindings/regulator/qcom,rpm-regulator.yaml b/Documentation/devicetree/bindings/regulator/qcom,rpm-regulator.yaml new file mode 100644 index 000000000000..8a08698e3484 --- /dev/null +++ b/Documentation/devicetree/bindings/regulator/qcom,rpm-regulator.yaml @@ -0,0 +1,128 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/regulator/qcom,rpm-regulator.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm RPM regulator + +description: + The Qualcomm RPM regulator is modelled as a subdevice of the RPM. + + Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,rpm.yaml + for information regarding the RPM node. + + The regulator node houses sub-nodes for each regulator within the device. + Each sub-node is identified using the node's name, with valid values listed + for each of the pmics below. + + For pm8058 l0, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, l12, l13, l14, l15, + l16, l17, l18, l19, l20, l21, l22, l23, l24, l25, s0, s1, s2, s3, s4, + lvs0, lvs1, ncp + + For pm8901 l0, l1, l2, l3, l4, l5, l6, s0, s1, s2, s3, s4, lvs0, lvs1, lvs2, lvs3, + mvs + + For pm8921 s1, s2, s3, s4, s7, s8, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, + l12, l14, l15, l16, l17, l18, l21, l22, l23, l24, l25, l26, l27, l28, + l29, lvs1, lvs2, lvs3, lvs4, lvs5, lvs6, lvs7, usb-switch, hdmi-switch, + ncp + + For pm8018 s1, s2, s3, s4, s5, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, + l12, l14, lvs1 + + For smb208 s1a, s1b, s2a, s2b + +maintainers: + -
