[PATCH v4 0/3] Support for Qualcomm QPNP PMIC's

[PATCH v4 0/3] Support for Qualcomm QPNP PMIC's

[Stanimir Varbanov]

Hello all,

Changes since v3:
 - rename the driver to qcom-spmi-pmic - suggested by David Collins
 - spmi regmap config now initialize .fast_io to true
 - added generalized comptatible string in DT binding document and driver
 - I dropped the pm8921 rename patch for now, it will be subject of another
   patchset later on.

regards,
Stan

--------------------------------------------------------------------------------

Changes since v2:
 - 1/4 - added new line, signed-off-by / acked-by and module_authors.
 - 3/4 - the subject has been changed.

The previous v2 can be found at [1].

I'm still waiting Acks for:
 - 4/4 from Qualcomm folks.
 - 2/4 and 3/4 from DT folks.

The patchset is ready to merge version and also it can be treated as an
intermediate step until we find a solution for non-translatable peripheral
addresses.

Hello everyone,

Here is the continuation of patch sets sent recently about Qualcomm
QPNP SPMI PMICs.

The previous version of the patch set can be found at [1].

Changes since v1:
 - removed completely custom *of* parser
 - renamed the mfd driver from qpnp-spmi to pm8xxx-spmi
 - now MFD_PM8XXX_SPMI Kconfig option depends on SPMI

Removing of the custom *of* parser leads to that that the *reg* devicetree
property cannot exist and therefore cannot be parsed to get PMIC peripheral
resources. I took this step aside because no one from mfd drivers does this
parsing. This will lead to inconvenience in the peripheral drivers to define
internally the SPMI base addresses depending on the compatible property
i.e. PMIC version. 

Comments are welcome!

[PATCH v4 1/3] mfd: add support for Qualcomm SPMI PMICs

[Stanimir Varbanov]

From: Josh Cartwright <joshc@codeaurora.org>

The Qualcomm SPMI PMIC chips are components used with the
Snapdragon 800 series SoC family.  This driver exists
largely as a glue mfd component, it exists to be an owner
of an SPMI regmap for children devices described in
device tree.

+          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,pm8941"
+                     "qcom,pm8841"
+                     "qcom,pma8084"
+                     or generalized "qcom,spmi-pmic".
+- reg:             Specifies the SPMI USID slave address for this device.
+                   For more information see:
+                   Documentation/devicetree/bindings/spmi/spmi.txt
+
+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.txt
+- 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 {

Kumar, Stephen, David can I have your Acked/Reviewed-by tag for 2/3 and
if possible for 3/3. The last patch can wait because currently we don't
have child peripherals. Thanks.

[PATCH v4 3/3] ARM: dts: qcom: add pm8941 and pm8841 PMICs device nodes

[Stanimir Varbanov]

The pm8941 and pm8841 spmi devicetree nodes are childrens of
spmi pmic arbiter. The msm8974 SoC uses two PMIC chips
pm8941 and pm8841. Every PMIC chip has two spmi bus slave id's.

If I am not missing something obvious, this patch needs to be resent as
it does not apply on top of patches in this series. I tried applying and
it fails in Kconfig.
