Subject: [PATCH 0/8] drm + usb-type-c: Add support for out-of-band hotplug notification (v4 resend)
Date: Tue, 17 Aug 2021 23:51:53 +0200 [thread overview]
Message-ID: <20210817215201.795062-1-hdegoede@redhat.com> (raw)
Hi all,
Here is a rebased-resend of v4 of my patchset making DP over Type-C work on
devices where the Type-C controller does not drive the HPD pin on the GPU,
but instead we need to forward HPD events from the Type-C controller to
the DRM driver.
Changes in v4 resend:
- Rebase on top of latest drm-tip
Changes in v4:
- Rebase on top of latest drm-tip
- Add forward declaration for struct fwnode_handle to drm_crtc_internal.h
(fixes warning reported by kernel test robot <lkp@intel.com>)
- Add Heikki's Reviewed-by to patch 7 & 8
- Add Heikki's Tested-by to the series
Changes in v3:
- Base on top of latest drm-tip, which should fix the CI being unable to
apply (and thus to test) the patches
- Make intel_acpi_assign_connector_fwnodes() take a ref on the fwnode
it stores in connector->fwnode and have drm_connector_cleanup() put
this reference
- Drop data argument from drm_connector_oob_hotplug_event()
- Make the Type-C DP altmode code only call drm_connector_oob_hotplug_event()
when the HPD bit in the status vdo changes
- Drop the platform/x86/intel_cht_int33fe: Correct "displayport" fwnode
reference patch, this will be merged independently through the pdx86 tree
Changes in v2:
- Replace the bogus "drm/connector: Make the drm_sysfs connector->kdev
device hold a reference to the connector" patch with:
"drm/connector: Give connector sysfs devices there own device_type"
the new patch is a dep for patch 2/9 see the patches
- Stop using a class-dev-iter, instead at a global connector list
to drm_connector.c and use that to find the connector by the fwnode,
similar to how we already do this in drm_panel.c and drm_bridge.c
- Make drm_connector_oob_hotplug_event() take a fwnode pointer as
argument, rather then a drm_connector pointer and let it do the
lookup itself. This allows making drm_connector_find_by_fwnode() a
drm-internal function and avoids code outside the drm subsystem
potentially holding on the a drm_connector reference for a longer
period.
This series not only touches drm subsys files but it also touches
drivers/usb/typec/altmodes/typec_displayport.c, that file usually
does not see a whole lot of changes. So I believe it would be best
to just merge the entire series through drm-misc, Assuming we can
get an ack from Greg for merging the typec_displayport.c changes
this way.
Regards,
Hans
