Subject: drm/i915/bxt: Define BXT power domains
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0b4a2a36d078b3a8de871025a958da547a6143f7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/i915/bxt: Define BXT power domains

Add BXT power domains

v2: Use DOMAIN_PLLS instead of a new CDCLK one, whitespace fixes
    (Damien)
v3: add VGA, TRANSCODER_A power domains (imre)
