Subject: [PATCH v2] dt-bindings: mfd: convert to yaml Qualcomm SPMI PMIC
Convert Qualcomm SPMI PMIC binding to yaml format.
Additional changes:
- filled many missing compatibles
Co-developed-by: Caleb Connolly <caleb@...nolly.tech>
Signed-off-by: David Heidelberg <david@...t.cz>
---
to pass tests correctly
depends on patch "arm64: dts: qcom: pms405: assign device specific compatible"
v2:
- changed author to myself, kept Caleb as co-author
- moved nodename to properties
- add nodenames for pm* with deprecated property
- add ^$ to pattern properties
- dropped interrupt-names property
- added reg prop. to the nodes which have register in nodename
- added compatible pmx55

- Qualcomm SPMI PMICs multi-function device bindings
-
-The Qualcomm SPMI series presently includes PM8941, PM8841 and PMA8084
-PMICs. These PMICs use a QPNP scheme through SPMI interface.
-QPNP is effectively a partitioning scheme for dividing the SPMI extended
-register space up into logical pieces, and set of fixed register
-locations/definitions within these regions, with some of these regions
-specifically used for interrupt handling.
-
-The QPNP PMICs are used with the Qualcomm Snapdragon series SoCs, and are
-interfaced to the chip via the SPMI (System Power Management Interface) bus.
-Support for multiple independent functions are implemented by splitting the
-16-bit SPMI slave address space into 256 smaller fixed-size regions, 256 bytes
-each. A function can consume one or more of these fixed-size register regions.
-
-Required properties:
-- compatible: Should contain one of:
- "qcom,pm660",
- "qcom,pm660l",
- "qcom,pm7325",
- "qcom,pm8004",
- "qcom,pm8005",
- "qcom,pm8019",
- "qcom,pm8028",
- "qcom,pm8110",
- "qcom,pm8150",
- "qcom,pm8150b",
- "qcom,pm8150c",
- "qcom,pm8150l",
- "qcom,pm8226",
- "qcom,pm8350c",
- "qcom,pm8841",
- "qcom,pm8901",
- "qcom,pm8909",
- "qcom,pm8916",
- "qcom,pm8941",
- "qcom,pm8950",
- "qcom,pm8994",
- "qcom,pm8998",
- "qcom,pma8084",
- "qcom,pmd9635",
- "qcom,pmi8950",
- "qcom,pmi8962",
- "qcom,pmi8994",
- "qcom,pmi8998",
- "qcom,pmk8002",
- "qcom,pmk8350",
- "qcom,pmr735a",
- "qcom,smb2351",
- or generalized "qcom,spmi-pmic".
-- reg: Specifies the SPMI USID slave address for this device.
- For more information see:
- Documentation/devicetree/bindings/spmi/spmi.yaml
-
-Required properties for peripheral child nodes:
-- compatible: Should contain "qcom,xxx", where "xxx" is a peripheral name.
-
-Optional properties for peripheral child nodes:
-- interrupts: Interrupts are specified as a 4-tuple. For more information
- see:
- Documentation/devicetree/bindings/spmi/qcom,spmi-pmic-arb.yaml
-- interrupt-names: Corresponding interrupt name to the interrupts property
-
-Each child node of SPMI slave id represents a function of the PMIC. In the
-example below the rtc device node represents a peripheral of pm8941
-SID = 0. The regulator device node represents a peripheral of pm8941 SID = 1.
-
-Example:
-
- spmi {
- compatible = "qcom,spmi-pmic-arb";
-
- pm8941@0 {
- compatible = "qcom,pm8941", "qcom,spmi-pmic";
- reg = <0x0 SPMI_USID>;
-
- rtc {
- compatible = "qcom,rtc";
- interrupts = <0x0 0x61 0x1 IRQ_TYPE_EDGE_RISING>;
- interrupt-names = "alarm";
- };
- };
-
- pm8941@1 {
- compatible = "qcom,pm8941", "qcom,spmi-pmic";
- reg = <0x1 SPMI_USID>;
-
- regulator {
- compatible = "qcom,regulator";
- regulator-name = "8941_boost";
- };
- };
- };
