This patch removes MODULE_DEVICE_TABLE definition to of_device_id

The patch adds driver for Exynos DSI master (DSIM). It is a platform driver
which is registered as exynos_drm_display sub-driver of exynos_drm framework
and implements DRM encoder/connector pair.
It is also MIPI-DSI host driver and provides DSI bus for panels.
It interacts with its panel(s) using drm_panel framework.Signed-off-by: Andrzej Hajda

Now that CRTC's have a primary plane, there's no need to track the
framebuffer in the CRTC. Replace all references to the CRTC fb with the
primary plane's fb.This patch was generated by the Coccinelle semantic patching tool using
the following rules:@@ struct drm_crtc C; @@
- (C).fb
+ C.primary->fb@@ struct drm_crtc *C; @@
- (C)->fb
+ C->primary->fbv3: Generate patch via coccinelle. Actual removal of crtc->fb has been
moved to a subsequent patch.v2: Fixup several lingering crtc->fb instances that were missed in the
first patch iteration. [Rob Clark]Signed-off-by: Matt Roper

The patch adds parallel output interface to FIMD device driver.

This patch implements drm_connector in the hdmi driver directly, instead

Signed-off-by: Inki Dae -
This creates a new display hook called create_connector. The purpose is
to allow the display driver to create its own drm_connector instead of
using the exynos_drm_connector. This moves things closer to completely
removing the exynos_drm_connector abstraction.Signed-off-by: Sean Paul

This patch removes all of the suspend/resume logic from the individual
drivers and consolidates it in drm_drv. This consolidation reduces the
number of functions which enable/disable the hardware to just one -- the
dpms callback. This ensures that we always power up/down in a consistent
manner.Signed-off-by: Sean Paul
Signed-off-by: Inki Dae -
This patch separates the fimd_activate function into poweron/poweroff
functions to be more consistent with the other drivers in exynos drm. It
also properly cleans up after failures in poweron. The functions have
also been shuffled around such that they are all in the same
spot in the file and poweron/poweroff can be called from the dpms function.Signed-off-by: Sean Paul

This patch moves the code from video/ to drm/. This is required the DP

This patch uses the mode passed into mode_set to configure fimd instead

This patch adds a new manager callback for mode_fixup and pipes it

Signed-off-by: Inki Dae -
This patch adds a mode_set callback to the manager operations which
sets the crtc's current mode to the manager driver. This will allow the
fimd driver to set its mode using values from drm, instead of the dt.Signed-off-by: Sean Paul
Signed-off-by: Inki Dae -
This patch moves the code which disables unused crtc planes from the
encoder to the crtc. Since there is a 1:1 encoder/crtc mapping in
exynos, the only valid crtc change the pre-existing code could catch is
disconnecting an active crtc from the encoder. Thus it is functionally
equivalent to just disable all planes attached to a crtc when the crtc
is disabled.Signed-off-by: Sean Paul
Signed-off-by: Inki Dae -
This patch changes the manual copying of mode to adjusted_mode in
mode_fixup to use drm_mode_copy instead of handling things manually.Signed-off-by: Sean Paul
Signed-off-by: Inki Dae -
This patch trims exynos_drm_hdmi out of the driver. The reason it
existed in the first place was to make up for the mixture of
display/overlay/manager ops being spread across hdmi and mixer. With
that code now rationalized, mixer and hdmi map directly to
exynos_drm_crtc and exynos_drm_encoder, respectively. Since there is a
1:1 mapping, we no longer need this layer.Signed-off-by: Sean Paul
Signed-off-by: Inki Dae -
The i2c client was previously being passed into the hdmi driver via a
dedicated i2c driver, and then a global variable. This patch removes all
of that and just uses the device tree to get the i2c_client. This patch
also properly references the client so we don't lose it before we're
done with it.Signed-off-by: Daniel Kurtz

Signed-off-by: Inki Dae -
This patch splits display and manager from subdrv. The result is that
crtc functions can directly call into manager callbacks and encoder
functions can directly call into display callbacks. This will allow
us to remove the exynos_drm_hdmi shim and support mixer/hdmi & fimd/dp
with common code.Signed-off-by: Sean Paul
