2022-05-04drm/rockchip: Add VOP2 driverAndy Yan
The VOP2 unit is found on Rockchip SoCs beginning with rk3566/rk3568. It replaces the VOP unit found in the older Rockchip SoCs. This driver has been derived from the downstream Rockchip Kernel and heavily modified: - All nonstandard DRM properties have been removed - dropped struct vop2_plane_state and pass around less data between functions - Dropped all DRM_FORMAT_* not known on upstream - rework register access to get rid of excessively used macros - Drop all waiting for framesyncs The driver is tested with HDMI and MIPI-DSI display on a RK3568-EVB board. Overlay support is tested with the modetest utility. AFBC support on the cluster windows is tested with weston-simple-dmabuf-egl on weston using the (yet to be upstreamed) panfrost driver support.

2022-05-04drm/rockchip: Make VOP driver optionalSascha Hauer
With upcoming VOP2 support VOP won't be the only choice anymore, so make the VOP driver optional. This also adds a dependency from ROCKCHIP_ANALOGIX_DP to ROCKCHIP_VOP, because that driver currently only links and works with the VOP driver.

2022-05-03drm/rockchip: Add crtc_endpoint_id to rockchip_encoderSascha Hauer
The VOP2 has an interface mux which decides to which encoder(s) a CRTC is routed to. The encoders and CRTCs are connected via of_graphs in the device tree. When given an encoder the VOP2 driver needs to know to which internal register setting this encoder matches. For this the VOP2 binding offers different endpoints, one for each possible encoder. The endpoint ids of these endpoints are used as a key from an encoders device tree description to the internal register setting. This patch adds the key aka endpoint id to struct rockchip_encoder plus a function to read the endpoint id starting from the encoders device node.

2022-05-02drm/rockchip: Refactor IOMMU initialisationRobin Murphy
Defer the IOMMU domain setup until after successfully binding components, so we can figure out IOMMU support directly from the VOP devices themselves, rather than manually inferring it from the DT (which also fails to account for whether the IOMMU driver is actually loaded). Although this is somewhat of a logical cleanup, the main motivation is to prepare for a change in the iommu_domain_alloc() interface.

Also we can return early for non-platform-devices if they are enabled, as rockchip_sub_drivers contains exclusively platform-devices.

2021-05-28drm/rockchip: remove existing generic drivers to take over the deviceJavier Martinez Canillas
There are drivers that register framebuffer devices very early in the boot process and make use of the existing framebuffer as setup by the firmware. If one of those drivers has registered a fbdev, then the fallback fbdev of the DRM driver won't be bound to the framebuffer console. To avoid that, remove any existing generic driver and take over the graphics device. By doing that, the fb mapped to the console is switched correctly from the early fbdev to the one registered by the rockchip DRM driver: [ 40.752420] fb0: switching to rockchip-drm-fb from EFI VGA Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Tested-by: Peter Robinson <pbrobinson@gmail.com> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Heiko Stuebner <heiko@sntech.de> Link: https://patchwork.freedesktop.org/patch/msgid/20210516074833.451643-1-javierm@redhat.com
2020-11-06drm/<drivers>: Constify struct drm_driverDaniel Vetter
Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const.

2019-04-18drm/rockchip: shutdown drm subsystem on shutdownVicente Bergas
As explained by Robin Murphy: > the IOMMU shutdown disables paging, so if the VOP is still > scanning out then that will result in whatever IOVAs it was using now going > straight out onto the bus as physical addresses. We had a more radical approach before in commit 7f3ef5dedb14 ("drm/rockchip: Allow driver to be shutdown on reboot/kexec") but that resulted in new warnings and oopses on shutdown on rk3399 chromeos devices. So second try is resurrecting Vicentes shutdown change which should achieve the same result but in a less drastic way.

2019-03-31drm: rockchip: introduce rk3066 hdmiZheng Yang
The RK3066 HDMI TX serves as interface between a LCD Controller and a HDMI bus. A HDMI TX consists of one HDMI transmitter controller and one HDMI transmitter PHY. The interface has three (3) 8-bit data channels which can be configured for a number of bus widths (8/10/12/16/20/24-bit) and different video formats (RGB, YCbCr). Features: HDMI version 1.4a, HDCP revision 1.4 and DVI version 1.0 compliant transmitter. Supports DTV resolutions from 480i to 1080i/p HD. Master I2C interface for a DDC connection. HDMI TX supports multiple power save modes. The HDMI TX input can switch between LCDC0 and LCDC1.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

This reverts commit 7f3ef5dedb146e3d5063b6845781ad1bb59b92b5. It causes new warnings [1] on shutdown when running the Google Kevin or Scarlet (RK3399) boards under Chrome OS. Presumably our usage of DRM is different than what Marc and Heiko test. We're looking at a different approach (e.g., [2]) to replace this, but IMO the revert should be taken first, as it already propagated to -stable.

2018-09-10drm/rockchip: Allow driver to be shutdown on reboot/kexecMarc Zyngier
Leaving the DRM driver enabled on reboot or kexec has the annoying effect of leaving the display generating transactions whilst the IOMMU has been shut down. In turn, the IOMMU driver (which shares its interrupt line with the VOP) starts warning either on shutdown or when entering the secondary kernel in the kexec case (nothing is expected on that front). A cheap way of ensuring that things are nicely shut down is to register a shutdown callback in the platform driver.
