X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4557c6072724fbb8e339b589e1897b20973b3b69;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Add MMIO helper for 6 ports with different offsets. Also new registers can have different mmio offsets per different lane per port. v2: Use _PICK as PORT3 instead of creating a new macro with if per port. v3: Use _PICK directly on MMIO_PORT6. While MMIO_PORT isn't flexible enough let's continue with MMIO_PORT6 as we have MMIO_PORT3.
