[PATCH v6 0/4] spi: dt-bindings: samsung: convert to dtschema

[Krzysztof Kozlowski]

Hi,

Changes since v5
================
1. Add new patch 3 (fix indentation in example).
2. Patch 2: reference spi-peripheral-props in else.
3. Add tags.

Changes since v4
================
1. Do not require samsung,spi-feedback-delay and fold patch 3 into patch 2.
2. Rework message in patch 4.
3. Add tags.

Changes since v3
================
1. Patch 2: correct path in exynos-usi.yaml.
2. Add patch 5.
3. Add tags.

Changes since v2
================
1. Patch 2: drop child device schema, as Rob suggested.

Changes since v1
================
1. Patch 2: describe devices matching compatible, correct issues pointed out by
   Rob, add reviewed-by tag.
2. New patches 3 and 4.

Best regards,
Krzysztof

[PATCH v6 1/4] spi: dt-bindings: samsung: convert to dtschema

[Krzysztof Kozlowski]

Convert the Samsung SoC (S3C24xx, S3C64xx, S5Pv210, Exynos) SPI
controller bindings to DT schema format.

The conversion also drops requirement from providing controller-data and
its data for each of SPI peripheral device nodes.  The dtschema cannot
express this and the requirement is being relaxed in the driver now.

-* Samsung SPI Controller
-
-The Samsung SPI controller is used to interface with various devices such as flash
-and display controllers using the SPI communication interface.
-
-Required SoC Specific Properties:
-
-- compatible: should be one of the following.
-    - samsung,s3c2443-spi: for s3c2443, s3c2416 and s3c2450 platforms
-    - samsung,s3c6410-spi: for s3c6410 platforms
-    - samsung,s5pv210-spi: for s5pv210 and s5pc110 platforms
-    - samsung,exynos5433-spi: for exynos5433 compatible controllers
-    - samsung,exynos7-spi: for exynos7 platforms <DEPRECATED>
-
-- reg: physical base address of the controller and length of memory mapped
-  region.
-
-- interrupts: The interrupt number to the cpu. The interrupt specifier format
-  depends on the interrupt controller.
-
-- dmas : Two or more DMA channel specifiers following the convention outlined
-  in bindings/dma/dma.txt
-
-- dma-names: Names for the dma channels. There must be at least one channel
-  named "tx" for transmit and named "rx" for receive.
-
-- clocks: specifies the clock IDs provided to the SPI controller; they are
-  required for interacting with the controller itself, for synchronizing the bus
-  and as I/O clock (the latter is required by exynos5433 and exynos7).
-
-- clock-names: string names of the clocks in the 'clocks' property; for all the
-  the devices the names must be "spi", "spi_busclkN" (where N is determined by
-  "samsung,spi-src-clk"), while Exynos5433 should specify a third clock
-  "spi_ioclk" for the I/O clock.
-
-Required Board Specific Properties:
-
-- #address-cells: should be 1.
-- #size-cells: should be 0.
-
-Optional Board Specific Properties:
-
-- samsung,spi-src-clk: If the spi controller includes a internal clock mux to
-  select the clock source for the spi bus clock, this property can be used to
-  indicate the clock to be used for driving the spi bus clock. If not specified,
-  the clock number 0 is used as default.
-
-- num-cs: Specifies the number of chip select lines supported. If
-  not specified, the default number of chip select lines is set to 1.
-
-- cs-gpios: should specify GPIOs used for chipselects (see spi-bus.txt)
-
-- no-cs-readback: the CS line is disconnected, therefore the device should not
-  operate based on CS signalling.
-
-SPI Controller specific data in SPI slave nodes:
-
-- The spi slave nodes should provide the following information which is required
-  by the spi controller.
-
-  - samsung,spi-feedback-delay: The sampling phase shift to be applied on the
-    miso line (to account for any lag in the miso line). The following are the
-    valid values.
-
-      - 0: No phase shift.
-      - 1: 90 degree phase shift sampling.
-      - 2: 180 degree phase shift sampling.
-      - 3: 270 degree phase shift sampling.
-
-Aliases:
-
-- All the SPI controller nodes should be represented in the aliases node using
-  the following format 'spi{n}' where n is a unique number for the alias.
-
-
-Example:
-
-- SoC Specific Portion:
-
-	spi_0: spi@12d20000 {
-		compatible = "samsung,exynos4210-spi";
-		reg = <0x12d20000 0x100>;
-		interrupts = <0 66 0>;

Hi Mark and Lee,

Thanks for the review. The dt-bindings part have Rob's review. I think
this means Lee can pick up the entire set (SPI+MFD)?

Best regards,
Krzysztof

It'd be good to have one in case it's needed.

[PATCH v6 4/4] spi: s3c64xx: allow controller-data to be optional

[Krzysztof Kozlowski]

The Samsung SoC SPI driver requires to provide controller-data node
for each of SPI peripheral device nodes.  Make this controller-data node
optional, so DTS could be simpler.

[PATCH v3 0/2] regulator/mfd: dt-bindings: maxim,max77802: convert to dtschema

[Krzysztof Kozlowski]

Hi,

Changes since v2
================
1. DTS patch: drop, applied.
2. Regulator: do not require regulator-names.
3. Add tags.

Changes since v1
================
1. MFD: Use absolute path to schemas.
2. Regulator: skip properties.

Dependencies
============
1. DTS patch: nothing depends on it, sending here so Rob's automatic
   checker won't complain about DTS.
   I will take it via Samsung SoC tree.

2. Final MFD patch depends on regulator, so the two last patches could
   go via Rob's, Mark's or Lee's trees.

Best regards,
Krzysztof

[PATCH v3 0/3] mfd/power/regulators: dt-bindings: max14577: convert to dtschema

[Krzysztof Kozlowski]

Hi,

Changes since v2
================
1. Add tags.
2. Drop DTS patch (applied).
3. mfd: Fix indentation in bindings example.
4. regulator: Drop regulator-name requirement and use
   unevaluatedProperties.

Changes since v1
================
1. MFD: Use absolute path to schemas
2. Regulator: mention all allowed properties,
   additionalProperties=false, add min/max values for voltages and
   current, don't use patternProperties when not needed.

Dependencies
============
1. DTS patch 1/4: nothing depends on it, sending here so Rob's automatic
   checker won't complain about DTS.
   I will take it via Samsung SoC tree.

2. Final MFD patch (4/4) depends on regulator and power, so the last
   patches (2+3+4) should go via same tree.

Best regards,
Krzysztof

[PATCH v2 0/5] mfd/extcon/regulators: max77843: add dtschema/bindings

[Krzysztof Kozlowski]

Hi,

The max77843 shares some parts with max77693 but it lacked bindings.  All
its compatibles were undocumented.  Add basic bindings for max77843,
matching existing devicetree.  These are not complete bindings, but
rather reverse-engineered to match current state.

I do not have access to device with MAX77843, so if anyone else
volunteers to be the bindings maintainer, please join.

Changes since v1
================
1. MFD: Use absolute path to schemas.
2. Regulator: mention all allowed properties,
   additionalProperties=false, add min/max values for voltages and
   current, don't use patternProperties when not needed.
3. extcon: Use absolute path to schemas.

Dependencies
============
1. Patch 1/5 (dts): nothing depends on it, sending here so Rob's automatic
   checker won't complain about DTS.
   I will take it via Samsung SoC tree.

2. The patch 4/5 (mfd bindings) depends on regulator and extcon, so they
   should come together (2+3+4+5).

Best regards,
Krzysztof
