Subject: [PATCH 0/2] drm/mipi-dsi: support low power transmission
Date: Mon, 18 Aug 2014 17:11:33 +0900	[thread overview]
Message-ID: <1408349495-25568-1-git-send-email-inki.dae@samsung.com> (raw)

This patch considers low power transmisson to two clock behaviors,
non-continuous and continuous clock mode.

These two clock behaviors can transmit data in high speed or low power.
So this patch series adds a new flag, MIPI_DSI_MODE_LPM so that each
host driver can setup its host controller properly.

Patch 1:
Add MIPI_DSI_MODE_LPM flag. If panel driver sets this flag, then msg->flags
will have MIPI_DSI_MSG_USE_LPM so that host driver can transmit data in low
power.

Patch 2:
Just exynos part for supporting non-continuous and continuous clock mode.

Inki Dae (2):
  drm/mipi-dsi: consider low power transmission
  drm/exynos: mipi-dsi: consider non-continuous clock mode
