The "max-brightness" is a standard backlight property that we need to support for the Samsung GT-I8190 Golden because the display will go black if we crank up the brightness too high. As the platform needs this ability to give picture this is a regression fix along with the addition of the property to the GT-I8190 device tree.

Hibmc use the devm_drm_dev_alloc function in hibmc_pci_probe, if hibmc_pci_probe returns non-zero, devm_drm_dev_alloc will call devm_drm_dev_init, which will call devm_drm_dev_init_release to release drm_dev_put. There is no need for hibmc to call drm_dev_put separately. Signed-off-by:

VIRTIO itself has no dependencies and therefore can easily be just select'ed, instead of depending on it. The current depends on causes any others trying to select VIRTIO to fail like this: drivers/gpu/drm/Kconfig:74:error: recursive dependency detected! drivers/gpu/drm/Kconfig:74: symbol DRM_KMS_HELPER is selected by DRM_VIRTIO_GPU drivers/gpu/drm/virtio/Kconfig:2: symbol DRM_VIRTIO_GPU depends on VIRTIO drivers/virtio/Kconfig:2: symbol VIRTIO is selected by GPIO_VIRTIO drivers/gpio/Kconfig:1618: symbol GPIO_VIRTIO depends on GPIOLIB drivers/gpio/Kconfig:14: symbol GPIOLIB is selected by I2C_MUX_LTC4306 drivers/i2c/muxes/Kconfig:47: symbol I2C_MUX_LTC4306 depends on I2C drivers/i2c/Kconfig:8: symbol I2C is selected by FB_DDC drivers/video/fbdev/Kconfig:63: symbol FB_DDC depends on FB drivers/video/fbdev/Kconfig:12: symbol FB is selected by DRM_KMS_FB_HELPER drivers/gpu/drm/Kconfig:80: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER It seems that having both 'depends on' as well as 'select' on the same symbol sends us into big trouble, and Kconfig can't break up the circular dependency (note that in the tested configuration, neither I2C, FB or DRM are enabled at all). Perhaps we could consider this a bug in Kconfig, but the trouble can easily be circumvented by changing 'depends on' into 'select'. DRM_VIRTIO_GPU also depends on VIRTIO_MENU, so even after this change, that option will only show up if the user already enabled virtio in the config. This change didn't cause any changes in the .config after menuconfig run, so we should be completely safe here. Signed-off-by:

User-space expects to be able to pick a primary plane for each CRTC exposed by the driver. Make sure this assumption holds in drm_mode_config_validate. Use the legacy drm_crtc.primary field to check this, because it's simpler and we require drivers to set it anyways. Accumulate a set of primary planes which are already used for a CRTC in a bitmask. Error out if a primary plane is re-used. v2: new patch v3: - Use u64 instead of __u64 (Jani) - Use `unsigned int` instead of `unsigned` (Jani) v4: - Use u32 instead of u64 for plane mask (Ville) - Use drm_plane_mask instead of BIT (Ville) - Fix typos (Ville) Signed-off-by:

The PHY initialisation parameters are not based on the pixel clock but the TMDS clock rate which can be the pixel clock in the standard case, but could be adjusted based on some parameters like the bits per color. Since the TMDS clock rate is stored in our custom connector state already, let's reuse it from there instead of computing it again. Acked-by:

The pixel rate is for now quite simple to compute, but with more features (30 and 36 bits output, YUV output, etc.) will depend on a bunch of connectors properties. Let's store the rate we have to run the pixel clock at in our custom connector state, and compute it in atomic_check. Acked-by:

drm_atomic_helper_connector_reset uses kmalloc which, from an API standpoint, can fail, and thus setting connector->state to NULL. However, our reset hook then calls drm_atomic_helper_connector_tv_reset that will access connector->state without checking if it's a valid pointer or not. Make sure we don't end up accessing a NULL pointer. Acked-by:

Commit 63495f6b ("drm/vc4: hdmi: Make sure our clock rate is within limits") was intended to compute the pixel rate to make sure we remain within the boundaries of what the hardware can provide. However, unlike what mode_valid was checking for, we forgot to take into account the clock doubling flag that can be set for modes. Let's honor that flag if it's there. Acked-by:
