Merge branch 'drm_iommu_v15' of https://github.com/markyzq/kernel-drm-rockchip into drm-next
Merge rockchip GPU support. This has a branch in common with the iommu tree, hopefully the process works. * 'drm_iommu_v15' of https://github.com/markyzq/kernel-drm-rockchip: dt-bindings: video: Add documentation for rockchip vop dt-bindings: video: Add for rockchip display subsytem drm: rockchip: Add basic drm driver dt-bindings: iommu: Add documentation for rockchip iommu iommu/rockchip: rk3288 iommu driver

Rockchip IOMMU
|
||||||
|
==============
|
||||||
|
|
||||||
|
A Rockchip DRM iommu translates io virtual addresses to physical addresses for
|
||||||
|
its master device. Each slave device is bound to a single master device, and
|
||||||
|
shares its clocks, power domain and irq.
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible : Should be "rockchip,iommu"
|
||||||
|
- reg : Address space for the configuration registers
|
||||||
|
- interrupts : Interrupt specifier for the IOMMU instance
|
||||||
|
- interrupt-names : Interrupt name for the IOMMU instance
|
||||||
|
- #iommu-cells : Should be <0>. This indicates the iommu is a
|
||||||
|
"single-master" device, and needs no additional information
|
||||||
|
to associate with its master device. See:
|
||||||
|
Documentation/devicetree/bindings/iommu/iommu.txt
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
vopl_mmu: iommu@ff940300 {
|
||||||
|
compatible = "rockchip,iommu";
|
||||||
|
reg = <0xff940300 0x100>;
|
||||||
|
interrupts = <GIC_SPI 16 IRQ_TYPE_LEVEL_HIGH>;
|
||||||
|
interrupt-names = "vopl_mmu";
|
||||||
|
#iommu-cells = <0>;

Rockchip DRM master device
|
||||||
|
================================
|
||||||
|
|
||||||
|
The Rockchip DRM master device is a virtual device needed to list all
|
||||||
|
vop devices or other display interface nodes that comprise the
|
||||||
|
graphics subsystem.
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible: Should be "rockchip,display-subsystem"
|
||||||
|
- ports: Should contain a list of phandles pointing to display interface port
|
||||||
|
of vop devices. vop definitions as defined in
|
||||||
|
Documentation/devicetree/bindings/video/rockchip-vop.txt
|
||||||
|
|
||||||
|
example:
|
||||||
|
|
||||||
|
display-subsystem {
|
||||||
|
compatible = "rockchip,display-subsystem";
|
||||||
|
ports = <&vopl_out>, <&vopb_out>;

device-tree bindings for rockchip soc display controller (vop)
|
||||||
|
|
||||||
|
VOP (Visual Output Processor) is the Display Controller for the Rockchip
|
||||||
|
series of SoCs which transfers the image data from a video memory
|
||||||
|
buffer to an external LCD interface.
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible: value should be one of the following
|
||||||
|
"rockchip,rk3288-vop";
|
||||||
|
|
||||||
|
- interrupts: should contain a list of all VOP IP block interrupts in the
|
||||||
|
order: VSYNC, LCD_SYSTEM. The interrupt specifier
|
||||||
|
format depends on the interrupt controller used.
|
||||||
|
|
||||||
|
- clocks: must include clock specifiers corresponding to entries in the
|
||||||
|
clock-names property.
|
||||||
|
|
||||||
|
- clock-names: Must contain
|
||||||
|
aclk_vop: for ddr buffer transfer.
|
||||||
|
hclk_vop: for ahb bus to R/W the phy regs.
|
||||||
|
dclk_vop: pixel clock.
|
||||||
|
|
||||||
|
- resets: Must contain an entry for each entry in reset-names.
|
||||||
|
See ../reset/reset.txt for details.
|
||||||
|
- reset-names: Must include the following entries:
|
||||||
|
- axi
|
||||||
|
- ahb
|
||||||
|
- dclk
|
||||||
|
|
||||||
|
- iommus: required a iommu node
|
||||||
|
|
||||||
|
- port: A port node with endpoint definitions as defined in
|
||||||
|
Documentation/devicetree/bindings/media/video-interfaces.txt.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
SoC specific DT entry:
|
||||||
|
vopb: vopb@ff930000 {
|
||||||
|
compatible = "rockchip,rk3288-vop";

|

|
||||||
|
clock-names = "aclk_vop", "dclk_vop", "hclk_vop";
|
||||||
|
resets = <&cru SRST_LCDC1_AXI>, <&cru SRST_LCDC1_AHB>, <&cru SRST_LCDC1_DCLK>;
|
||||||
|

|

|
vopb_out: port {
|

|
#address-cells = <1>;
