The first three patches are fixups that are hopefully straight forward, integrating feedback I got from Laurant. One of the previous patches that Laurant had concerns about, I broke into two patches, which are the last two in this series. The core issue seems to be something going wrong with the regmap cache state for the ADV7511_REG_EDID_I2C_ADDR (0x43) register which results in i2c_transfer errors if we don't do the regcache_sync/_mark_dirty() calls. I suspect there might be a better solution there, so suggestions will be very welcome. Thoughts and feedback would be appreciated! thanks -john Cc: David Airlie Cc: Archit Taneja Cc: Wolfram Sang Cc: Lars-Peter Clausen Cc: Laurent Pinchart Cc: dri-devel@lists.freedesktop.org Archit Taneja (1): drm/bridge: adv7511: Enable HPD interrupts to support hotplug and improve monitor detection John Stultz (4): drm/bridge: adv7511: Use work_struct to defer hotplug handing to out of irq context drm/bridge: adv7511: Switch to using drm_kms_helper_hotplug_event() drm/bridge: adv7511: Rework adv7511_power_on/off() so they can be reused internally drm/bridge: adv7511: Reuse __adv7511_power_on/off() when probing EDID drivers/gpu/drm/bridge/adv7511/adv7511.h | 2 ++ drivers/gpu/drm/bridge/adv7511/adv7511_drv.c | 49 ++++++++++++++++------------ 2 files changed, 31 insertions(+), 20 deletions(-) -- 2.7.4
