[Intel-gfx] [PATCH 3/4] drm/i915: convert vlv_dpio_read()/write() from pipe to phy

Jani Nikula jani.nikula at intel.com
Mon Nov 13 16:47:10 UTC 2023


vlv_dpio_read() and vlv_dpio_write() really operate on the phy, not
pipe. Passing the pipe instead of the phy as parameter is supposed to be
a convenience, but when the caller has the phy, it becomes an
inconvenience. See e.g. chv_dpio_cmn_power_well_enable() and
assert_chv_phy_powergate().

Figure out the phy in the callers, and pass phy to the dpio functions.
