[PATCH 0/3] Support reflect-x/y on RK3328, RK3368, and RK3399

[Ezequiel Garcia]

Here's a small series supporting plane reflection (aka. mirroring)
properties on RK3328, RK3368, and RK3399 SoCs.

Note that RK3288 specification doesn't seem to document registers
for plane mirroring, but instead it only seems to support mirroring
at the display (CRTC) level.

A small typo cleanup patch is included, in patch 1. Not related
to the rotation stuff.

In order to support this feature, patch 2 separates the register
set for win0 and win1.

Once that's done, patch 3 creates the properties, if supported
by each plane/SoC.

The following modetest commands would test this feature,
where 30 is the plane ID, and 49 = rotate_0 + relect_y + reflect_x.
    
X mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:17
    
Y mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:33
    
XY mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:49

This work has been originally by Daniele. I just cleaned
up the implementation a it, and ported the code to upstream.

This series is based on drm-misc-next plus https://patchwork.kernel.org/patch/10752893/.

[PATCH 1/3] drm/rockchip: Fix typo in VOP macros argument

[Ezequiel Garcia]

Fix a small typo in the macros VOP argument. The macro argument
is currently wrongly named "x", and then never used. The code
built fine almost by accident, as the macros are always used
in a context where a proper "vop" symbol exists.

This fix is almost cosmetic, as the resulting code shouldn't change.

[PATCH 2/3] drm/rockchip: Separate RK3288 from RK3368 win01 registers

[Ezequiel Garcia]

This commit splits the registers for RK3288 from those
for RK3328, RK3368 and RK3399. It seems RK3288 does not
support plane x-y-mirroring, and so in order to support this
for the other SoCs, we need to have separate set of registers
for win0 and win1.

[PATCH 3/3] drm/rockchip: Add reflection properties

[Ezequiel Garcia]

From: Daniele Castagna <dcastagna@chromium.org>

Add the KMS plane rotation property to the DRM rockchip driver,
for SoCs RK3328, RK3368 and RK3399.

RK3288 only supports rotation at the display level (i.e. CRTC),
but for now we are only interested in plane rotation.

This commit only adds support for the value of reflect-y
and reflect-x (i.e. mirroring).

Note that y-mirroring is not compatible with YUV.

The following modetest commands would test this feature,
where 30 is the plane ID, and 49 = rotate_0 + relect_y + reflect_x.

X mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:17

Y mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:33

XY mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:49
