X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bb879a44ffd5f708be14b1578239e51b2a4555e8;p=openwrt%2Fstaging%2Fblogic.git

drm/i915: add definition of DDI buffer translations regs

Those registers are used to train DDI buffer translations for each link
type.

v2: access each port registers through the DDI_BUF_TRANS macro
