Convert s5p-mfc bindings to DT schema format using json-schema.
Signed-off-by: Aakarsh Jain <[email protected]>
---
changes since v4:
Removed items from oneOf section
dropped black line
defined the iommus names items as
items:
-const left
-const right
changes since v3:
fixed dt-schema warnings and errors while running make dtbs_check and make dt_binding_check for ARMv7
Since, obsolete properties are not part of dt-node so we are not including these properties in dt-schema.
changes since v2:
changed Commit message from Adds to Convert
Removed text "This file has moved to samsung,s5p-mfc.yaml" from s5p-mfc.txt
fixed dt-schema warnings and errors while running make dtbs_check and make dt_binding_check
changes since v1:
fixed dt-schema warnings and errors while running make dtbs_check and make dt_binding_check
Removed description.
Listed items.
Added allOf:if:then for restricting two items to specific compatible
This patch is independent from the previous MFC v12 patch series for HW3 support.

-* Samsung Multi Format Codec (MFC)
-
-Multi Format Codec (MFC) is the IP present in Samsung SoCs which
-supports high resolution decoding and encoding functionalities.
-The MFC device driver is a v4l2 driver which can encode/decode
-video raw/elementary streams and has support for all popular
-video codecs.
-
-Required properties:
- - compatible : value should be either one among the following
- (a) "samsung,mfc-v5" for MFC v5 present in Exynos4 SoCs
- (b) "samsung,mfc-v6" for MFC v6 present in Exynos5 SoCs
- (c) "samsung,exynos3250-mfc", "samsung,mfc-v7" for MFC v7
- present in Exynos3250 SoC
- (d) "samsung,mfc-v7" for MFC v7 present in Exynos5420 SoC
- (e) "samsung,mfc-v8" for MFC v8 present in Exynos5800 SoC
- (f) "samsung,exynos5433-mfc" for MFC v8 present in Exynos5433 SoC
- (g) "samsung,mfc-v10" for MFC v10 present in Exynos7880 SoC
-
- - reg : Physical base address of the IP registers and length of memory
- mapped region.
-
- - interrupts : MFC interrupt number to the CPU.
- - clocks : from common clock binding: handle to mfc clock.
- - clock-names : from common clock binding: must contain "mfc",
- corresponding to entry in the clocks property.
-
-Optional properties:
- - power-domains : power-domain property defined with a phandle
- to respective power domain.
- - memory-region : from reserved memory binding: phandles to two reserved
- memory regions, first is for "left" mfc memory bus interfaces,
- second if for the "right" mfc memory bus, used when no SYSMMU
- support is available; used only by MFC v5 present in Exynos4 SoCs
-
-Obsolete properties:
- - samsung,mfc-r, samsung,mfc-l : support removed, please use memory-region
- property instead
-
-
-Example:
-SoC specific DT entry:
-
-mfc: codec@13400000 {
- compatible = "samsung,mfc-v5";
- reg = <0x13400000 0x10000>;
- interrupts = <0 94 0>;
- power-domains = <&pd_mfc>;
- clocks = <&clock 273>;
- clock-names = "mfc";
-};
-
-Reserved memory specific DT entry for given board (see reserved memory binding
-for more information):
-
-reserved-memory {
- #address-cells = <1>;
- #size-cells = <1>;
- ranges;
-
- mfc_left: region@51000000 {
- compatible = "shared-dma-pool";
- no-map;
- reg = <0x51000000 0x800000>;
- };

- compatible = "shared-dma-pool";
- no-map;
- reg = <0x43000000 0x800000>;

Why this and first enum are separate? I didn't notice it before...
Usually we have only one enum for one-compatible variants. Also, sort
them by compatible.

What happened to iommus? You were requiring two items, but you dropped
that requirement. Is it on purpose?

You sill have here odd indentation. Use 4 spaces for DTS example.

okay.
I will keep it in this way
properties:
compatible:
oneOf:
- const: samsung,mfc-v5 # Exynos4
- const: samsung,mfc-v6 # Exynos5
- const: samsung,mfc-v7 # Exynos5420
- const: samsung,mfc-v8 # Exynos5800
- const: samsung,exynos5433-mfc # Exynos5433
- const: samsung,mfc-v10 # Exynos7880
- items:
- const: samsung,exynos3250-mfc # Exynos3250
- const: samsung,mfc-v7 # Fall back for Exynos3250
Will this be fine?
