[PATCH 0/3] mmc: samsung,exynos-dw-mshc: convert to dtschema

[PATCH 0/3] mmc: samsung,exynos-dw-mshc: convert to dtschema

[Krzysztof Kozlowski]

Hi,

I will take the DTS patches via Samsung SoC.  The MMC dt-bindings patch
probably via MMC or Rob's tree.

Best regards,
Krzysztof

-* Samsung Exynos specific extensions to the Synopsys Designware Mobile
-  Storage Host Controller
-
-The Synopsys designware mobile storage host controller is used to interface
-a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
-differences between the core Synopsys dw mshc controller properties described
-by synopsys-dw-mshc.txt and the properties used by the Samsung Exynos specific
-extensions to the Synopsys Designware Mobile Storage Host Controller.
-
-Required Properties:
-
-* compatible: should be
-	- "samsung,exynos4210-dw-mshc": for controllers with Samsung Exynos4210
-	  specific extensions.
-	- "samsung,exynos4412-dw-mshc": for controllers with Samsung Exynos4412
-	  specific extensions.
-	- "samsung,exynos5250-dw-mshc": for controllers with Samsung Exynos5250
-	  specific extensions.
-	- "samsung,exynos5420-dw-mshc": for controllers with Samsung Exynos5420
-	  specific extensions.
-	- "samsung,exynos7-dw-mshc": for controllers with Samsung Exynos7
-	  specific extensions.
-	- "samsung,exynos7-dw-mshc-smu": for controllers with Samsung Exynos7
-	  specific extensions having an SMU.
-	- "axis,artpec8-dw-mshc": for controllers with ARTPEC-8 specific
-	  extensions.
-
-* samsung,dw-mshc-ciu-div: Specifies the divider value for the card interface
-  unit (ciu) clock. This property is applicable only for Exynos5 SoC's and
-  ignored for Exynos4 SoC's. The valid range of divider value is 0 to 7.
-
-* samsung,dw-mshc-sdr-timing: Specifies the value of CIU clock phase shift value
-  in transmit mode and CIU clock phase shift value in receive mode for single
-  data rate mode operation. Refer notes below for the order of the cells and the
-  valid values.
-
-* samsung,dw-mshc-ddr-timing: Specifies the value of CUI clock phase shift value
-  in transmit mode and CIU clock phase shift value in receive mode for double
-  data rate mode operation. Refer notes below for the order of the cells and the
-  valid values.
-* samsung,dw-mshc-hs400-timing: Specifies the value of CIU TX and RX clock phase
-  shift value for hs400 mode operation.
-
-  Notes for the sdr-timing and ddr-timing values:
-
-    The order of the cells should be
-      - First Cell: CIU clock phase shift value for tx mode.
-      - Second Cell: CIU clock phase shift value for rx mode.
-
-    Valid values for SDR and DDR CIU clock timing for Exynos5250:
-      - valid value for tx phase shift and rx phase shift is 0 to 7.
-      - when CIU clock divider value is set to 3, all possible 8 phase shift
-        values can be used.
-      - if CIU clock divider value is 0 (that is divide by 1), both tx and rx
-        phase shift clocks should be 0.
-
-* samsung,read-strobe-delay: RCLK (Data strobe) delay to control HS400 mode
-  (Latency value for delay line in Read path)
-
-Required properties for a slot (Deprecated - Recommend to use one slot per host):
-
-* gpios: specifies a list of gpios used for command, clock and data bus. The
-  first gpio is the command line and the second gpio is the clock line. The
-  rest of the gpios (depending on the bus-width property) are the data lines in
-  no particular order. The format of the gpio specifier depends on the gpio
-  controller.
-(Deprecated - Refer to Documentation/devicetree/bindings/pinctrl/samsung-pinctrl.txt)
-
-Example:
-
-  The MSHC controller node can be split into two portions, SoC specific and
-  board specific portions as listed below.
-
-	dwmmc0@12200000 {
-		compatible = "samsung,exynos5250-dw-mshc";
-		reg = <0x12200000 0x1000>;

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/mmc/samsung,exynos-dw-mshc.example.dtb:0:0: /example-0/mmc@12200000: failed to match any schema with compatible: ['samsung,exynos5420-dw-mshc-smu']

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
