Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
Summary: - Add code cleanups and bug fixups. - Add a new display controller dirver, DECON which is a new display controller of Exynos7 SoC. This device is much different from FIMD of Exynos4 and Exynos4 SoC series. * 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: drm/exynos: Add DECON driver drm/exynos: fix NULL pointer reference drm/exynos: remove exynos_plane_dpms drm/exynos: remove mode property of exynos crtc drm/exynos: Remove exynos_plane_dpms() call with no effect drm/exynos: fix DMA_ATTR_NO_KERNEL_MAPPING usage drm/exynos: hdmi: replace fb size with mode size from win commit drm/exynos: fix no hdmi output drm/exynos: use driver internal struct drm/exynos: fix wrong pipe calculation for crtc drm/exynos: remove to use unnecessary MODULE_xxx macro drm/exynos: remove DRM_EXYNOS_DMABUF config drm/exynos: IOMMU support should not be selectable by user drm/exynos: add support for 'hdmi' clock

Device-Tree bindings for Samsung Exynos7 SoC display controller (DECON)
|
||||
|
||||
DECON (Display and Enhancement Controller) is the Display Controller for the
|
||||
Exynos7 series of SoCs which transfers the image data from a video memory
|
||||
buffer to an external LCD interface.
|
||||
|
||||
Required properties:
|
||||
- compatible: value should be "samsung,exynos7-decon";
|
||||
|
||||
- reg: physical base address and length of the DECON registers set.
|
||||
|
||||
- interrupt-parent: should be the phandle of the decon controller's
|
||||
parent interrupt controller.
|
||||
|
||||
- interrupts: should contain a list of all DECON IP block interrupts in the
|
||||
order: FIFO Level, VSYNC, LCD_SYSTEM. The interrupt specifier
|
||||
format depends on the interrupt controller used.
|
||||
|
||||
- interrupt-names: should contain the interrupt names: "fifo", "vsync",
|
||||
"lcd_sys", in the same order as they were listed in the interrupts
|
||||
property.
|
||||
|
||||
- pinctrl-0: pin control group to be used for this controller.
|
||||
|
||||
- pinctrl-names: must contain a "default" entry.
|
||||
|
||||
- clocks: must include clock specifiers corresponding to entries in the
|
||||
clock-names property.
|
||||
|
||||
- clock-names: list of clock names sorted in the same order as the clocks
|
||||
property. Must contain "pclk_decon0", "aclk_decon0",
|
||||
"decon0_eclk", "decon0_vclk".
|
||||
- i80-if-timings: timing configuration for lcd i80 interface support.
|
||||
|
||||
Optional Properties:
|
||||
- samsung,power-domain: a phandle to DECON power domain node.
|
||||
- display-timings: timing settings for DECON, as described in document [1].
|
||||
Can be used in case timings cannot be provided otherwise
|
||||
or to override timings provided by the panel.

<&clock_disp SCLK_DECON_INT_ECLK>,

||||
<&clock_disp SCLK_DECON_INT_EXTCLKPLL>;
|
||||
clock-names = "pclk_decon0", "aclk_decon0", "decon0_eclk",
|
||||
"decon0_vclk";
|

status = "disabled";

};
|

Board specific DT entry:
|

decon@13930000 {
|

pinctrl-0 = <&lcd_clk &pwm1_out>;
|

pinctrl-names = "default";
