drm: renesas: Add zpos, alpha and blend properties to RZ/G2L DU
Add support for zpos, alpha and blend properties to RZ/G2L DU
driver as the IP supports all these properties.
It is tested by the below modetest commands:
modetest -M rzg2l-du -s 44@42:1920x1080@AR24 -d -P \
37@42:512x300+200+200@XR15
modetest -M rzg2l-du -w {32,37}:alpha:{0,65535}
modetest -M rzg2l-du -w {32,37}:zpos:{0,1}
