Subject: [PATCH v5 02/11] drm: Add support_bits parameter to drm_property_create_bitmask()

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Make drm_property_create_bitmask() a bit more generic by allowing the
caller to specify which bits are in fact supported. This allows multiple
callers to use the same enum list, but still create different versions
of the same property with different list of supported bits.

v5: Fixed the caller of this function in omapdrm to comply with supported
bitmask definition.

How can it be v5 w/o any v2,v3,v4?

In any case I think this is still broken. I'll reply with a new patch...

Subject: [PATCH v2 02/11] drm: Add support_bits parameter to drm_property_create_bitmask()

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Make drm_property_create_bitmask() a bit more generic by allowing the
caller to specify which bits are in fact supported. This allows multiple
callers to use the same enum list, but still create different versions
of the same property with different list of supported bits.

v2: Populate values[] array as non-sparse
Make supported_bits 64bit
Fix up omapdrm call site (Rob)

This should also make my original "drm: Add drm_mode_create_rotation_property()"
patch do the right thing. So patch 03/11 of the series needs to be replaced with the
original.
