Pull driver core updates from Greg KH: "Here is the set of driver core changes for 5.18-rc1. Not much here, primarily it was a bunch of cleanups and small updates: - kobj_type cleanups for default_groups - documentation updates - firmware loader minor changes - component common helper added and take advantage of it in many drivers (the largest part of this pull request). All of these have been in linux-next for a while with no reported problems" * tag 'driver-core-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (54 commits) Documentation: update stable review cycle documentation drivers/base/dd.c : Remove the initial value of the global variable Documentation: update stable tree link Documentation: add link to stable release candidate tree devres: fix typos in comments Documentation: add note block surrounding security patch note samples/kobject: Use sysfs_emit instead of sprintf base: soc: Make soc_device_match() simpler and easier to read driver core: dd: fix return value of __setup handler driver core: Refactor sysfs and drv/bus remove hooks driver core: Refactor multiple copies of device cleanup scripts: get_abi.pl: Fix typo in help message kernfs: fix typos in comments kernfs: remove unneeded #if 0 guard ALSA: hda/realtek: Make use of the helper component_compare_dev_name video: omapfb: dss: Make use of the helper component_compare_dev power: supply: ab8500: Make use of the helper component_compare_dev ASoC: codecs: wcd938x: Make use of the helper component_compare/release_of iommu/mediatek: Make use of the helper component_compare/release_of drm: of: Make use of the helper component_release_of ...

drm/meson: Use drm_module_platform_driver() to register the driver

2022-01-27T18:15:46+00:00

The macro calls to a DRM specific platform driver init handler that checks whether the driver is allowed to be registered or not. Signed-off-by: Javier Martinez Canillas Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20211217003752.3946210-13-javierm@redhat.com

drm/meson: Fix error handling when afbcd.ops->init fails

2022-01-03T11:28:37+00:00

When afbcd.ops->init fails we need to free the struct drm_device. Also all errors which come after afbcd.ops->init was successful need to exit the AFBCD, just like meson_drv_unbind() does.

drm/meson: osd_afbcd: Add an exit callback to struct meson_afbcd_ops

Use this to simplify the driver shutdown. It will also come handy when fixing the error handling in meson_drv_bind_master().

drm: Remove CONFIG_DRM_KMS_CMA_HELPER option

2021-11-30T10:10:03+00:00

Link drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPER has been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. Selecting KMS helpers and CMA will now automatically enable CMA KMS helpers. Some drivers' Kconfig files did not correctly select KMS or CMA helpers. Fix this as part of the change.

drm/meson: encoder_cvbs: switch to bridge with ATTACH_NO_CONNECTOR

2021-11-12T09:10:01+00:00

Drop the local connector and move all callback to bridge funcs in order to leverage the generic CVBS display connector. This will also permit adding custom cvbs connectors for ADC based HPD detection on some Amlogic SoC based boards.

drm/meson: encoder_hdmi: switch to bridge DRM_BRIDGE_ATTACH_NO_CONNECTOR

2021-11-12T09:10:01+00:00

This implements the necessary change to no more use the embedded connector in dw-hdmi and use the dedicated bridge connector driver by passing DRM_BRIDGE_ATTACH_NO_CONNECTOR to the bridge attach call. The necessary connector properties are added to handle the same functionalities as the embedded dw-hdmi connector, i.e. the HDR metadata, the CEC notifier & other flags. The dw-hdmi output_port is set to 1 in order to look for a connector next bridge in order to get DRM_BRIDGE_ATTACH_NO_CONNECTOR working.

drm/meson: split out encoder from meson_dw_hdmi

2021-11-12T09:09:19+00:00

This moves all the non-DW-HDMI code where it should be: an encoder in the drm/meson core driver. The bridge functions are copied as-is, except: - the encoder init uses the simple kms helper - the mode_set has been moved to atomic_enable() - debug prints are converted to dev_debg() For now the bridge attach flags is 0, DRM_BRIDGE_ATTACH_NO_CONNECTOR will be handled later. The meson dw-hdmi glue is slightly fixed to live without the encoder in the same driver.
