[PATCH v3 0/5] DT: Improve validation for Marvell SoCs

[PATCH v3 0/5] DT: Improve validation for Marvell SoCs

[Lubomir Rintel]

Hi,

chained to this message is what remains of the patch set that converts
binding documents for hardware used with Marvell MMP SoCs to JSON.

Compared to v2 there are fixes to the first two patches. Detailed
changelogs are in the individual patches.

Thanks
Lubo

[PATCH v3 1/5] dt-bindings: gpio: Convert mrvl-gpio to json-schema

[Lubomir Rintel]

This converts the mrvl-gpio binding to DT schema format using json-schema.

Various fixes were done during the conversion, such as adding more
properties that are in fact mandatory or extending the examples to
include child nodes with extra GPIO blocks.

The compatible strings are a mess. It is not clear why so many of them
are needed; the driver doesn't really seem to differentiate between the
models. Some of them, like marvell,pxa93x-gpio and marvell,pxa1928-gpio
are not used at all, so it's not known how many interrupts they utilize.
On the other hand, mrvl,pxa-gpio has been seen in the tree, but it
doesn't end up in any actual DTB file.

In any case -- the schema merely copies whatever was in the original
binding document, so it's hopefully no more wrong that the original.

Changes since v2:
- Don't make ranges property mandatory

Changes since v1:
- Drop marvell,pxa1928-gpio
- Drop ranges from example with no gcb child nodes
- Add default GPL-2.0-only license tag
- Fill in maintainers from MAINTAINERS file

[PATCH v3 2/5] dt-bindings: i2c: Convert i2c-pxa to json-schema

[Lubomir Rintel]

A conversion of the i2c-pxa binding to DT schema format using json-schema.

This also cleans ups some errors in the binding: The compatible string
description suggested that "mmp" in "mrvl,mmp-twsi" is to be substituted
with a processor model, which wouldn't be a right thing to do and indeed
nobody seems to have been doing that. There also was "Recommended
properties" section that included optional as well as mandatory
properties. Missing mandatory properties were added to the example.

-- reg : Address and length of the register set of the interrupt controller.
-  If the interrupt controller is intc, address and length means the range
-  of the whole interrupt controller. The "marvell,mmp3-intc" controller
-  also has a secondary range for the second CPU core.  If the interrupt
-  controller is mux-intc, address and length means one register. Since
-  address of mux-intc is in the range of intc. mux-intc is secondary

-- reg-names : Name of the register set of the interrupt controller. It's
-  only required in mux-intc interrupt controller.
-- interrupts : Should be the port interrupt shared by mux interrupts. It's
-  only required in mux-intc interrupt controller.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an

-- interrupt-controller : Declare this node to be an interrupt controller.
-- reg : Interrupt mask address. A list of 4 byte ranges, one per controller.

[PATCH v3 4/5] dt-bindings: rtc: Convert sa1100-rtc to json-schema

[Lubomir Rintel]

Convert the sa1100-rtc binding to DT schema format using json-schema.
While add that, add clocks and resets that are actually used.

Signed-off-by: Lubomir Rintel <lkundrak@v3.sk>

---
Changes since v1:
- Remove interrupts/maxItems
- Mention clocks and resets in the patch description
- Add default GPL-2.0-only license tag
- Fill in maintainers from MAINTAINERS file

Acked-by: Linus Walleij <linus.walleij@linaro.org>

I expect Rob will apply it when he's happy with it, else poke me once
