Subject: [PATCH v5 0/5] Add r8a77965 DRIF support

Dear All,

this series is to add DRIF support for the r8a77965
(a.k.a. R-Car M3-N). Version 5 fixes a warning reported
by 'make dt_binding_check', as reported by Rob.

Thanks,
Fab

-Renesas R-Car Gen3 Digital Radio Interface controller (DRIF)
-------------------------------------------------------------
-
-R-Car Gen3 DRIF is a SPI like receive only slave device. A general
-representation of DRIF interfacing with a master device is shown below.
-
-+---------------------+ +---------------------+
-| |-----SCK------->|CLK |
-| Master |-----SS-------->|SYNC DRIFn (slave) |
-| |-----SD0------->|D0 |
-| |-----SD1------->|D1 |
-+---------------------+ +---------------------+
-
-As per datasheet, each DRIF channel (drifn) is made up of two internal
-channels (drifn0 & drifn1). These two internal channels share the common
-CLK & SYNC. Each internal channel has its own dedicated resources like
-irq, dma channels, address space & clock. This internal split is not
-visible to the external master device.
-
-The device tree model represents each internal channel as a separate node.
-The internal channels sharing the CLK & SYNC are tied together by their
-phandles using a property called "renesas,bonding". For the rest of
-the documentation, unless explicitly stated, the word channel implies an
-internal channel.
-
-When both internal channels are enabled they need to be managed together
-as one (i.e.) they cannot operate alone as independent devices. Out of the
-two, one of them needs to act as a primary device that accepts common
-properties of both the internal channels. This channel is identified by a
-property called "renesas,primary-bond".
-
-To summarize,
- - When both the internal channels that are bonded together are enabled,
- the zeroth channel is selected as primary-bond. This channels accepts
- properties common to all the members of the bond.
- - When only one of the bonded channels need to be enabled, the property
- "renesas,bonding" or "renesas,primary-bond" will have no effect. That
- enabled channel can act alone as any other independent device.
-
-Required properties of an internal channel:
--------------------------------------------
-- compatible: "renesas,r8a7795-drif" if DRIF controller is a part of R8A7795 SoC.
- "renesas,r8a7796-drif" if DRIF controller is a part of R8A7796 SoC.
- "renesas,rcar-gen3-drif" for a generic R-Car Gen3 compatible device.
-
- When compatible with the generic version, nodes must list the
- SoC-specific version corresponding to the platform first
- followed by the generic version.
-
-- reg: offset and length of that channel.
-- interrupts: associated with that channel.
-- clocks: phandle and clock specifier of that channel.
-- clock-names: clock input name string: "fck".
-- dmas: phandles to the DMA channels.
-- dma-names: names of the DMA channel: "rx".
-- renesas,bonding: phandle to the other channel.
-
-Optional properties of an internal channel:
--------------------------------------------
-- power-domains: phandle to the respective power domain.
-
-Required properties of an internal channel when:
- - It is the only enabled channel of the bond (or)
- - If it acts as primary among enabled bonds
---------------------------------------------------------
-- pinctrl-0: pin control group to be used for this channel.
-- pinctrl-names: must be "default".
-- renesas,primary-bond: empty property indicating the channel acts as primary
- among the bonded channels.
-- port: child port node corresponding to the data input, in accordance with
- the video interface bindings defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt. The port
- node must contain at least one endpoint.
-
-Optional endpoint property:
----------------------------
-- sync-active: Indicates sync signal polarity, 0/1 for low/high respectively.
- This property maps to SYNCAC bit in the hardware manual. The
- default is 1 (active high).

Patch 1/5 to 4/5 taken in my tree, I'll send a pull request to
linux-media when the merge window closes. I expect Geert to handle 5/5.

With latest dt-schema, "make dt_binding_check" complains:

Documentation/devicetree/bindings/media/renesas,drif.yaml:
properties:clock-names:maxItems: False schema does not allow 1
Documentation/devicetree/bindings/media/renesas,drif.yaml:
ignoring, error in schema: properties: clock-names: maxItems

Using

clock-names:
const: fck

Fixes that.

However, I'm wondering why I do not get a complaint about the similar
clock/clock-names in
Documentation/devicetree/bindings/display/bridge/renesas,lvds.yaml.
Because they're part of an else branch?

Thanks!

Do you need me to send a new version or are you going to amend
this on your end?

Interesting, renesas,lvds.yaml doesn't seem to trigger the problem
from within the "then" branch either if I hack it, it only seems to
trigger the problem when outside the if statement.

We probably need to remove "maxItems: 1" from renesas,lvds.yaml as
well though, what do you think?

Patch 5 has been merged, but patches 1-4 aren't. I don't think there
was a PR for it. For some reason these patches are delegated to me in
patchwork. I've now delegated them to you for further processing.

Probably. if/then/else schemas have fewer checks as they can be
incomplete (only additional constraints on the top-level schema).
