[PATCH v2 5/8] drm/i915/display_power: use intel_de_*() functions for register access

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Generated using the following semantic patch:
