[PATCH] gpu: ipu-v3: replace spin_lock_irqsave by spin_lock in hard IRQ

[PATCH drm/hisilicon 0/3] support reading resolutions from EDID

[Tian Tao]

patch #1 add a new file to implements i2c adapters, #2 read the
resolution from the edid, if that fails, set the resolution to fixed.
patch #3 update the destroy callback function to release the i2c adapters.

Tian Tao (3):
  drm/hisilicon: Support i2c driver algorithms for bit-shift adapters
  drm/hisilicon: Features to support reading resolutions from EDID
  drm/hisilicon: Releasing Resources in the Destroy callback Function
