[0/4] drm/msm/dpu: Qualcomm SC8180x MDSS/DPU support

Message

These patches adds MDSS and DPU support for the Qualcomm SC8180x platform.

The platform supports running 2 pixels per pixel clock cycle and the bootloader
enables this, so the first patch adds enough support to the DPU driver to
disable this again.

The second patch shoots down the data path configured in CTL_0, as the DPU
driver picks CTL_2 on the laptops, causing graphical artifacts.

The third patch adds the SC8180x to the hw catalog.

The forth patch is included for "completeness", but needs to be reworked. It
updates the IRQ mapping for INTF_5, which is where we find the eDP controller.

Bjorn Andersson (3):
  drm/msm/dpu: Introduce knowledge of widebus feature
  drm/msm/dpu: Clear boot loader configured data paths
  dpu: hack up the irq table for 8180 intf_5
