Subject: drm/i915/lt_phy: Replace crtc compute clock
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=968e9fd188488d1a4b6981f39554d4117468b6ee;p=thirdparty%2Flinux.git

drm/i915/lt_phy: Replace crtc compute clock

The existing DPLL compute clock callback for the XE3PLPD platform
(`xe3plpd_crtc_compute_clock`) was specific to that platform. Replace it
with the more generic Haswell (`hsw_crtc_compute_clock`) implementation
so that the compute clock path does not rely on the XE3PLPD hook.
