The global mode_config.rotation_property is going away, switch over to
per-plane rotation_property.
I was trying to test this on msm/drm using modetest. The 180 rotation
works fine, but drm rejects reflect-x and reflect-y rotation prop
values. Is this expected?
I needed to make this modification to get reflect-x/y working too:
diff --git a/drivers/gpu/drm/drm_atomic.c b/drivers/gpu/drm/drm_atomic.c

That makes no sense. You _must_ to pass one and only one rotation angle.
In *addition* you can pass any number of the reflection flags.
Okay. Does the rotation property also include reflection flags, though?
Yes.
When I dump plane properties using modetest, I get:
31 rotation:
flags: bitmask
values: rotate-0=0x1 rotate-180=0x4 reflect-x=0x10 reflect-y=0x20
value: 1
If I use modetest to set 0x10 or 0x20, it returns an error. I wanted to
know if this is expected behavior or not?
It is. If you want 0 degree rotation with X reflection you have to pass
0x11.
Ah okay, didn't realize I had to put a 0 degree rotation along with the
reflect. Works fine with 0x11. Thanks for the clarification.

Thanks,

return -EINVAL;
state->rotation = val;
} else if (property == plane->zpos_property) {
Otherwise, the patches look fine to me.
Thanks,

v2: Drop the BIT()
