[U-Boot] [PATCH v6 22/26] tegra: video: Support serial output resource (SOR) on tegra124

Simon Glass
2015-04-15T03:03:40Z

The SOR is required for talking to eDP LCD panels. Add a driver for this
which will be used by the DisplayPort driver.

Signed-off-by: Simon Glass <sjg@chromium.org>
---

Changes in v6:
- Add more debug() statements

Changes in v4: None
Changes in v3:
- Reorder parameters to tegra_dc_sor_attach()
- Simplify timouts to remove repeated multiplication by 1000

Changes in v2: None
