On ipp subsystem removal list of ipp drivers is traversed and their members are deleted. To do it properly safe version of list_for_each* should be used. Signed-off-by:

FIMC in default mode of operation uses only one input buffer, but the driver used also second buffer, as a result only the first frame was processed correctly. The patch fixes it. Signed-off-by:

To correctly disable hardware window during driver init, both enable bits (WINCONx_ENWIN in WINCON and SHADOWCON_CHx_ENABLE in SHADOWCON) must be cleared, otherwise hardware fails to re-enable such window later. While touching this function, also temporarily disable ctx->suspended flag to let fimd_wait_for_vblank function really to do its job. Signed-off-by:

Commit [0] stopped setting fix.smem_start and fix.smem_len when creating the fbdev. [0] 2f1eab8d drm/exynos/fbdev: don't set fix.smem/mmio_{start,len} However, smem_len is used by some userland applications to calculate the size for mmap. In particular, it is used by xf86-video-fbdev: http://cgit.freedesktop.org/xorg/xserver/tree/hw/xfree86/fbdevhw/fbdevhw.c?id=xorg-server-1.15.99.903#n571 So, let's restore setting the smem_len to unbreak things for these users. Note: we are still leaving smem_start set to 0. Reported-by:

This patch adds Exynos3250/3472 SoCs support. Signed-off-by:

Inki Dae authored
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. Signed-off-by:

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.

The type of this function is unsigned long, and it is expected to return proper fout value or zero if something is wrong. So this patch fixes wrong return value for error cases. Signed-off-by:

Commit "drm/rcar-du: Use struct videomode in platform data" touches board code in arch/arm/mach-shmobile. There is, to the best of my knowledge, no risk of conflict for v3.18. Simon, are you fine with getting those changes merged through Dave's tree (and could you confirm that no conflict should occur) ? Simon acked the merge: Acked-by:

While zone->name is currently hard coded, the call to kobject_init_and_add() should follow the more defensive argument list usage (as already done in other places in ttm_memory.c) where "%s" is used instead of directly passing in a variable as a format string. Signed-off-by:

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. Tested-by:

Instead of setting an initial value for the return code, set it explicitly on each error path. This is just a cosmetic cleanup, as preparation for the enable GPIO support. Tested-by:

The current backlight support is broken; the driver expects a backlight-class in the panel devicetree node. Fix this by implementing it properly, getting an optional backlight from a phandle. This shouldn't cause any backward-compatibility DT issue because the current implementation doesn't work and is not even documented. Tested-by:

The current error path calls tilcdc_unload() in case of an error to release the resources. However, this is wrong because not all resources have been allocated by the time an error occurs in tilcdc_load(). To fix it, this commit adds proper labels to bail out at the different stages in the load function, and release only the resources actually allocated. Tested-by:
