Correct; thanks for pointing this out.
IMO, this value should be 0x4003ffff because the fields are actually
present in the register (even though the interfaces/pipes.etc. are not).
Anyway, these bits won't be accessed because the driver won't even allow
the usage of the corresponding resources.
I will update in the v2 of "drm/msm/mdp5: Add hardware configuration for
msm8x16".
Thanks,
Stephane.
