2014-09-20drm/exynos: use drm generic mmap interfaceInki Dae5-132/+16
This patch removes DRM_EXYNOS_GEM_MMAP ictrl feature specific to Exynos drm and instead uses drm generic mmap. We had used the interface specific to Exynos drm to do mmap directly, not to use demand paging which maps each page with physical memory at page fault handler. We don't need the specific mmap interface because the drm generic mmap which uses vm offset manager stuff can also do mmap directly. This patch makes a userspace region to be mapped with whole physical memory region allocated by userspace request when mmap system call is requested. Changelog v2: - do not set VM_IO, VM_DONTEXPEND and VM_DONTDUMP. These flags were already set by drm_gem_mmap - do not include <linux/anon_inodes.h>, which isn't needed anymore.

2014-09-20drm/exynos: mipi-dsi: consider non-continuous clock modeInki Dae1-0/+19
This patch adds non-continuous clock mode support Clock mode on Clock Lane is continuous clock by default. So if we want to transmit data in non-continuous clock mode to reduce power consumption, then host driver should set DSIM_CLKLANE_STOP bit. In this case, host controller turns off HS clock between high speed transmissions. For this, this patch adds a new bit, DSIM_CLKLANE_STOP, and makes the host driver sets this bit only in case that dsi->mode_flags has MIPI_DSI_CLOCK_NON_CONTINUOUS flag.

2014-09-20drm/mipi-dsi: consider low power transmissionInki Dae2-0/+8
This patch adds a new flag, MIPI_DSI-MODE_LPM, to transmit data in low power. With this flag, msg.flags has MIPI_DSI_MSG_USE_LPM so that host driver of each SoC can clear or set relevant register bit for low power transmission. All host drivers shall support continuous clock behavior on the Clock Lane, and optionally may support non-continuous clock behavior. Both of them can transmit data in high speed of low power. With each clock behavior, non-continuous or continuous clock mode, host controller will transmit data in high speed by default so if peripheral wants to receive data in low power, the peripheral driver should set MIPI_DSI_MODE_LPM flag.

In order to support the "enable GPIO" available in many panel devices, this commit adds a proper devicetree binding. By providing an enable GPIO in the devicetree, the driver can now turn off and on the panel device, and/or the backlight device. Both the backlight and the GPIO are optional properties.
