X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=89eff4bea721700d1f4d5ffd3fdc99bb0de9e962;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: fix wrong PLL debug messages. LPT does have PCH refclk, but it's different form the IBX/CPT/PPT one and doesn't use the same structs. It is wrong to have a message saying that "LPT does not has PCH refclk" (sic). While at it, signal that we only want this function on IBX/CPT/PPT by renaming it and adding a WARN. On HSW we also print "0 shared PLLs initialized", but we *do* have shared PLLs on HSW (LCPLL, WRPLL, SPLL) and we *do* initialize them. We just don't use "struct intel_shared_dpll". So remove the debug message. In the future we may want to rename all that "intel shared pll" code to "ibx shared pll", but I'll leave this to another patch.
