This patch set adds the Tegra dc one-shot support. The patch set is tested on Dalmore + Sharp lq101r1sx01.
Please be noticed that the patch #12 is not part of the feature, it's just used for testing.
Changes in v2: - Define one-shot flag in drm_display_mode->private_flags, according to Daniel's comments - Remove the "te-polarity" property in dts. The TE polarity is determined by panel so there is not necessary to define it in DTS. We can define it in panel driver. - Rebased the patch series on top of 6/29 linux-next. - Fix a bug in DSI suspend DPMS event, to wait DSI idle before suspend - Fix a bug in DSI driver to correct the DPMS state(patch #11)
