Merge branch 'drm-tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into drm-next
* removes the now unused DRM slave encoder support, which all users have migrated away from, allowing us to simplify the code. * ensure all pending interrupts are processed together, rather than needing the handler to be re-entered each time. * use more HDMI helpers to setup the info frames. * fix EDID read handling by ensuring that we always wait the specified time before attempting to read the EDID, no matter where the EDID read request came from. * 'drm-tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: drm/i2c: tda998x: clean up after struct tda998x_priv2 removal drm/i2c: tda998x: kill struct tda998x_priv2 drm/i2c: tda998x: move connector into struct tda998x_priv drm/i2c: tda998x: remove encoder pointer drm/i2c: tda998x: remove DRM slave encoder support drm/i2c: tda998x: use more HDMI helpers drm/i2c: tda998x: handle all outstanding interrupts drm/i2c: tda998x: convert to u8/u16/u32 types drm/i2c: tda998x: re-implement "Fix EDID read timeout on HDMI connect" drm/i2c: tda998x: report whether we actually handled the IRQ drm/i2c: tda998x: remove useless NULL checks
