[PATCH v3 0/6] drm/rockchip: fixes and new features

[PATCH v3 0/6] drm/rockchip: fixes and new features

[Mark Yao]

This series patches are used for yuv image overlay display.

Rockchip vop support NV11, NV16, NV24 yuv format,
and can scale the image scale 1/8 to 8.

Changes in v3:
- make code more readable
- fix some bugs

Changes in v2:
- Uv buffer not support odd offset, align it.
- Fix error display when move yuv image. 
- Fix scale dest info. 
Mark Yao (6):
  drm/rockchip: vop: Fix virtual stride calculation
  drm/rockchip: vop: Fix window dest start point
  drm/rockchip: vop: Add yuv plane support
  drm/rockchip: vop: Default enable win2/3 area0 bit
  drm/rockchip: vop: restore vop registers when resume
  drm/rockchip: vop: support plane scale

[PATCH v3 1/6] drm/rockchip: vop: Fix virtual stride calculation

[Mark Yao]

vir_stride need number words of the virtual width, and fb->pitches
save bytes_per_pixel, so just div 4 switch to stride.

Hmm, I found the patch ("drm/rockchip: Add BGR formats to VOP")
is on the drm-fixes branch, so I didn't resend the patch.

Ok, I will rebase these patches top of the "Add BGR formats to VOP".

Hmm, I found the patch ("drm/rockchip: Add BGR formats to VOP")
is on the drm-fixes branch, so I didn't resend the patch.

Ok, I will rebase these patches top of the "Add BGR formats to VOP".

[PATCH v3 4/6] drm/rockchip: vop: Default enable win2/3 area0 bit

[Mark Yao]

Win2/3 support multiple area function, but we haven't found
a suitable way to use it yet, so let's just use them as other windows
with only area 0 enabled.

this could go as fix into 4.2 please.

With what is currently in 4.2-rc3 I'm loosing the mouse cursor in my xf86-
armsoc xserver [0]. Likely due to 0915da7dd75f ("drm/rockchip: vop: remove 
hardware cursor window"). The xserver then selects a window for the cursor 
itself, which seems to be one of the currently disabled ones.

This patch fixes this and gives me back my cursor :-)

[PATCH v3 6/6] drm/rockchip: vop: support plane scale

[Mark Yao]

Win_full support 1/8 to 8 scale down/up engine, support
all format scale.

Signed-off-by: Mark Yao <mark.yao@rock-chips.com>
---
Changes in v3:
Adviced by Tomasz Figa
- remove unused code and unnecessary scale path.
- use static inline funcion instead "#define", let gcc check the cast
- move same call into helper, make code clean.

Changes in v2:
- Fix scale dest info.

[PATCH v3 6/6] drm/rockchip: vop: support plane scale

[Mark Yao]

Win_full support 1/8 to 8 scale down/up engine, support
all format scale.

Signed-off-by: Mark Yao <mark.yao@rock-chips.com>
---
Changes in v3:
Adviced by Tomasz Figa
- remove unused code and unnecessary scale path.
- use static inline funcion instead "#define", let gcc check the cast
- move same call into helper, make code clean.

Changes in v2:
- Fix scale dest info.
