If src_x/y were nonzero, we failed to shift them down by 16 to get the pixel offset. The recent CMA helper function gets it right. Signed-off-by:

This cuts 135 lines of boilerplate, at the cost of losing the filtering of get_modes() using atmel_hlcdc_dc_mode_valid(). The atomic check will still check that we don't set an invalid mode, though. Acked-by:

The newer version of the RPi panel driver is going to be a combination of a bridge and a panel, but we should also support panels without a bridge, so the panel-bridge layer lets us do that cleanly. v2: Drop "dev" argument. Signed-off-by:

Many DRM drivers have common code to make a stub connector implementation that wraps a drm_panel. By wrapping the panel in a DRM bridge, all of the connector code (including calls during encoder enable/disable) goes away. v2: Fix build with CONFIG_DRM=m, drop "dev" argument that should just be the panel's dev, move kerneldoc up a level and document _remove(). v3: Fix another breakage with CONFIG_DRM=m, fix breakage with CONFIG_OF=n, move protos under CONFIG_DRM_PANEL_BRIDGE, wrap a line.

Now that we have a callback to check if bridge supports a given mode we can use it in Synopsys Designware HDMI bridge so that we restrict the number of probbed modes to the ones we can actually display. Also, there is no need to use mode_fixup() callback as mode_valid() will handle the mode validation. NOTE: I also had to change the pdata declaration of mode_valid custom callback so that the passed modes are const. I also changed in the platforms I found. Not even compiled it though. Signed-off-by:

IRQs are properly shut down, so it almost works as race-free shutdown. Except the irq is stopped after the vblank stuff, so boom anyway. Proper way would be to call drm_atomic_helper_shutdown before any of the kms things gets stopped. So no harm in removing the drm_vblank_cleanup here really.

The driver is written in a way to enable compile-testing without CONFIG_ARM_AMBA, but it just causes needless warnings: drivers/gpu/drm/pl111/pl111_drv.c:149:26: error: 'pl111_drm_driver' defined but not used [-Werror=unused-variable] drivers/gpu/drm/pl111/pl111_drv.c:81:12: error: 'pl111_modeset_init' defined but not used [-Werror=unused-function] This unhides the probe/remove functions again and just leaves the driver object as unused when CONFIG_ARM_AMBA is disabled, with a __maybe_unused annotation to shut up the warning.

CRTC don't seem to get shut down in a controlled fashion, but no one bothers to stop interrupts either so this races no matter what. Might as well remove it. A call to drm_atomic_helper_shutdown would be pretty sweet somewhere (and maybe getting rid of the load/unload callbacks while at it). Cc: Alexey Brodkin <abrodkin@synopsys.com> Reviewed-by:

It's only done in the driver load error path, where vblanks don't need to be quiescent anyway. And that's all drm_vblank_cleanup does, since the core will release the vblank allocations on its own already. So drop it. Cc: Philipp Zabel <p.zabel@pengutronix.de> Acked-by:

This changes the connector probe helper function to use the new encoder->mode_valid(), bridge->mode_valid() and crtc->mode_valid() helper callbacks to validate the modes. The new callbacks are optional so the behaviour remains the same if they are not implemented. If they are, then the code loops through all the connector's encodersXbridgesXcrtcs and calls the callback. If at least a valid encoderXbridgeXcrtc combination is found which accepts the mode then the function returns MODE_OK. Signed-off-by:

This is a leftover from the drm_bus days, where we've had a bus-specific device type for every bus type in drm_device. Except for pci (which we can't remove because dri1 drivers) this is all gone. And the virt driver also doesn't really need it, dev_to_virtio works perfectly fine.
