b9578c4945 dma-buf/heaps: Correct the types of fd_flags and heap_flags
dma_heap_allocation_data defines the UAPI as follows:

 struct dma_heap_allocation_data {
        __u64 len;
        __u32 fd;
        __u32 fd_flags;
        __u64 heap_flags;
 };

But dma heaps are casting both fd_flags and heap_flags into
unsigned long. This patch makes dma heaps - cma heap and
system heap have consistent types with UAPI.

drm: bridge: simple-bridge: use devm_drm_bridge_add in probe
simple_bridge_probe() calls drm_bridge_add()
Thus, drm_bridge_remove() must be called in the remove() callback.

If we call devm_drm_bridge_add() instead, then drm_bridge_remove()
will be called automatically at device release, and the remove()
callback is no longer required.

1ac6ac9ec0 drm/panic: depends on !VT_CONSOLE
The race condition between fbcon and drm_panic can only occurs if
VT_CONSOLE is set. So update drm_panic dependency accordingly.
This will make it easier for Linux distributions to enable drm_panic
by disabling VT_CONSOLE, and keeping fbcon terminal.
The only drawback is that fbcon won't display the boot kmsg, so it
should rely on userspace to do that.
At least plymouth already handle this case with

0743dafefd drm: zynqmp_kms: Fix AUX bus not getting unregistered
drm_encoder_cleanup is responsible for calling drm_bridge_detach for
each bridge attached to the encoder. zynqmp_dp_bridge_detach is in turn
responsible for unregistering the AUX bus. However, we never ended up
calling drm_encoder_cleanup in the remove or error paths, so the AUX bus
would stick around after the rest of the driver had been removed.

I don't really understand why drm_mode_config_cleanup doesn't call
drm_encoder_cleanup for us. It will call destroy (which for
simple_encoder is drm_encoder_cleanup) on encoders in the mode_config's
encoder_list.

Should drm_encoder_cleanup get called before or after
drm_atomic_helper_shutdown?

drm/bridge: sii902x: Fix mode_valid hook
Currently, mode_valid is defined only in drm_connector_helper_funcs.
When the bridge is attached with the 'DRM_BRIDGE_ATTACH_NO_CONNECTOR'
flag, the connector is not initialized, and so is the mode_valid
hook under connector helper funcs.
It also returns MODE_OK for all modes without actually checking the
modes.
So move the mode_valid hook to drm_bridge_funcs with proper clock
checks for maximum and minimum pixel clock supported by the bridge.

The connector's status depends on the physical connector's status.
The BMC is only connected if the physical connector is not. This
is necessary to support userspace clients that can only handle a
single output per CRTC.

The BMC is a server feature. Add a BMC output for all server chips,

6b4468b0c6 drm/bridge-connector: implement glue code for HDMI connector
In order to let bridge chains implement HDMI connector infrastructure,
add necessary glue code to the drm_bridge_connector. In case there is a
bridge that sets DRM_BRIDGE_OP_HDMI, drm_bridge_connector will register
itself as a HDMI connector and provide proxy drm_connector_hdmi_funcs
implementation.

Note, to simplify implementation, there can be only one bridge in a
chain that sets DRM_BRIDGE_OP_HDMI. Setting more than one is considered
an error. This limitation can be lifted later, if the need arises.

78f15847bd drm/panel: raydium-rm67191: Don't call unprepare+disable at shutdown
It's the responsibility of a correctly written DRM modeset driver to
call drm_atomic_helper_shutdown() at shutdown time and that should be
disabling / unpreparing the panel if needed. Panel drivers shouldn't
be calling these functions themselves.

A recent effort was made to fix as many DRM modeset drivers as
possible [1] [2] [3] and most drivers are fixed now.

A grep through mainline for compatible strings used by this driver
indicates that it is used by IMX boards. The IMX driver appears to be
correctly calling drm_atomic_helper_shutdown() so we can remove the
calls.

b7c906d680 drm/panel: raydium-rm67191: Stop tracking enabled
As talked about in commit d2aacaf073 ("drm/panel: Check for already
prepared/enabled in drm_panel"), we want to remove needless code from
panel drivers that was storing and double-checking the
prepared/enabled state. Even if someone was relying on the
double-check before, that double-check is now in the core and not
needed in individual drivers.

The conversion of the rm67191 panel driver follows many of the other
panel drivers but has a few differences that need to be called out.

Like in commit 1e0465eb16 ("drm/panel: otm8009a: Don't double check
prepared/enabled"), this panel also uses the "prepared" flag to
prevent the backlight functions from running when the panel is powered
off. This is probably not the safest thing to do but the old behavior
was preserved. See the discussion in the otm8009a patch. Because of
this, I've left the driver tracking "prepared" but removed its
tracking of "enabled".

NOTE: as part of this, transition the panel's direct calls to its
disable/unprepare functions in shutdown to call through DRM panel.
