If the clipped dirty region's x/y happened to align to 256, we would have set the top 8 bits wrong. Noticed by inspection, not by reproducing a bug. Signed-off-by:

I want to sort out support for tinydrm in vc4, so I needed to get a tinydrm-appropriate panel working and this is what I had on hand. This is derived from a combination of ili9341.c from tinydrm and fb_hx8357d.c from staging's fbtft. v2: Write my own register defs from the spec to not need the header from fbtft. Fix spi device string to enable module autoloading. (Suggestions by Noralf) Signed-off-by: -

This adds a new binding for Himax HX8357D display panels. It includes a compatible string for one display (more can be added in the future). The YX350HV15 panel[1] is found in the Adafruit PiTFT 3.5" Touch Screen for Raspberry Pi. [1] https://learn.adafruit.com/adafruit-pitft-3-dot-5-touch-screen-for-raspberry-pi/downloads This binding is closely modeled after the ili9341 binding, for a similar product from adafruit. The primary difference is that the hx8357d doesn't have a reset line that I can find in the schematics. v2: Document the "reg" property (requested by Rob), fix commit message typo (Noralf) Signed-off-by:

Add the Rockchip-sepcific dual-dsi setup and hook it into the VOP as well. As described in the general dual-dsi devicetree binding, the panel should define two input ports and point each of them to one of the used dsi- controllers, as well as declare one of them as clock-master. This is used to determine the dual-dsi state and get access to both controller instances. v6: handle master+slave component in dsi-attach v5: use driver-internal mechanism to find dual dsi slave v4: add component directly in probe when adding empty dsi slave controller Signed-off-by:

Allow to also drive a slave dw-mipi-dsi controller in a dual-dsi setup. This will require additional implementation-specific code to look up the slave instance and do specific setup. Also will probably need code in the specific crtcs as dual-dsi does not equal two separate dsi outputs. To activate, the implementation-specific code should set the slave using dw_mipi_dsi_set_slave() before calling __dw_mipi_dsi_bind(). v2: - expect real interface number of lanes - keep links to both master and slave v3: - remove unneeded separate variables - remove unneeded second slave settings - disable slave before master - lane-sum calculation comments Signed-off-by:

With the regular means of adding the dsi-component in probe it creates a race condition with the panel probing, as the panel device only gets created after the dsi-bus got created. When the panel-driver is build as a module it currently fails hard as the panel cannot be probed directly: dw_mipi_dsi_bind() __dw_mipi_dsi_probe() creates dsi bus creates panel device triggers panel module load panel not probed (module not loaded or panel probe slow) drm_bridge_attach fails with -EINVAL due to empty panel_bridge Additionally the panel probing can run concurrently with dsi bringup making it possible that the panel can already be found but dsi-attach hasn't finished running. To solve that cleanly we may want to only create the component after the panel has finished probing, by calling component_add from the host-attach dsi callback. As that is specific to glue drivers, add a new struct for host_ops so that glue drivers can tell the bridge to call specific functions after the common host-attach and before the common host-detach run. Suggested-by: -
Heiko Stuebner authored
__dw_mipi_dsi_probe() does all the grabbing of resources and does it using devm-helpers. So this is happening on each try of master bringup possibly slowing down things a lot. Drivers using the component framework may instead want to call dw_mipi_dsi_probe separately in their probe function to setup resources early. That way the dsi bus also gets created earlier and also not recreated on each bind-try, so that attached panels can load their modules and be probed way before the bridge-attach in the bind call. So drop the call to __dw_mipi_dsi_probe and modify the function to take a struct dw_mipi_dsi instead of the platform-device. Signed-off-by:

Right now the host is only unregistered when the driver is used via the bridge api and not via the component api, leading to the host staying registered in cases like probe deferral. So move the host unregister to the general remove function, so that it gets cleaned up in all cases. Signed-off-by:

Earlier commit updated the vgem driver to improve the topology, by passing a platform device as parent to drm_dev_init(). Shortly afterwords we updated the core function to BUG() in order to catch any buggy drivers passing NULL as parent. While I missed the vkms driver (as the patch predates vkms by a few months), the BUG caught the issue within couple of hours. Swap the drm_dev_init <> platform_device_register_simple order, to the driver back to life.

HDMI 2.0 monitors may not support SCDC and still be able to accept VICs above 63. Use multiple EDID capbilities to determine if the SINK is actually an HDMI 2.0 device. The QD980B HDMI 2.0 Analyzer generates unique EDIDs during CTS tests that don't contain a HDMI Forum VSDB if the block is not used during the test. The current HDMI AVI infoframe code only uses the SCDC supported information in the HDMI Forum VSDB to determine if the sink is HDMI 2.0. This patch adds a check for YCbCr420 present in the EDID supported formats as well as the existing SCDC supported check. HDMI 2.0 CTS HF1-51 test fails on the QD980B.

The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.

A while back we removed it, yet that lead to regressions. At some later point, I've attempted to remove it again without fully grasping the unique (pun intended) situation that virtio is in. Add a bulky comment to document why the call should stay as-is, for the next person who's around. As a Tl;Dr: virtio sits on top of struct virtio_device, which confuses dev_is_pci(), wrong info gets sent to userspace and X doesn't start.
