[PATCH v2 0/7] R-Car Salvator-X M3-W: Enable DU support

[PATCH v2 0/7] R-Car Salvator-X M3-W: Enable DU support

[Laurent Pinchart]

Hello,

This patch series enables DU support for the M3-W-based Salvator-X board.

Display support has no out-of-tree compile or runtime dependencies. HDMI
output support has a runtime dependency on

- [PATCH] clk: renesas: r8a7796: Add HDMI clock
- [PATCH 1/2] drm: rcar-du: Restrict DPLL duty cycle workaround to H3 ES1.x
- [PATCH 2/2] drm: rcar-du: Add HDMI outputs to R8A7796 device description

The first patch is queued for v4.13, the last two patches will be sent
upstream for v4.14. As the HDMI output will be automatically skipped by the DU
driver until the dependencies are available, this series can be queued for
v4.14 already without requiring any synchronization with the DRM/KMS tree.

[PATCH v2 1/7] dt-bindings: display: renesas: Add R-Car M3-W HDMI TX DT bindings

[Laurent Pinchart]

The M3-W HDMI TX controller seems to be compatible for the H3. No
extension to the DT bindings are needed, add an SoC-specific compatible
string in case differences between the IP versions are found later and
require model-specific handling.

Applied for v4.14.

I am not applying the dts changes for now pending resolution of the
potential bisection problem in patch 4 which I pointed out in response to that patch.

[PATCH v2 2/7] arm64: dts: renesas: r8a7796: Add FCPF and FCPV instances

[Laurent Pinchart]

The FCPs handle the interface between various IP cores and memory. Add
the instances related to the FDPs and VSP2s.
