[Intel-gfx] [RFC 07/33] drm/i915/ddi: use intel_de_*() functions for register access
Jani Nikula
jani.nikula at intel.com
Fri Jan 24 13:25:28 UTC 2020
The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().
Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().
No functional changes.
