Subject: [PATCH v1 0/5] gpu/drm: tegra: add DSI support for Tegra20/Tegra30

Tegra20/Tegra30 DSI is quite similar to Tegra114+ apart MIPI calibration
logic and clocks. With a few minor tweaks, existing tegra DSI driver
should work on Tegra20/Tegra30 devices just fine. Tested on
Motorola Atrix 4G (T20) and ASUS VivoTab RT TF600T (T30).

Svyatoslav Ryhel (5):
  dt-bindings: display: tegra: document MIPI calibration for
    Tegra20/Tegra30
  clk: tegra20: reparent dsi clock to pll_d_out0
  gpu/drm: host1x: mipi: add Tegra20/Tegra30 MIPI calibration logic
  gpu/drm: tegra: dsi: add support for Tegra20/Tegra30
  ARM: tegra: add MIPI calibration binding for Tegra20/Tegra30
