After we acquired all generic modeset locks in drm_modeset_lock_all, it's
unsafe acquire any other so just mark acquisition as done.
Atomic drivers shouldn't use drm_modeset_lock_all.

With the addition of "private_objs" in drm_atomic_state, we no longer
need to subclass drm_atomic_state to store state of share resources
that don't perfectly fit within planes/crtc/connector state information.

This replaces the usage of the subclassed atomic state (mdp5_state)

The new API replaces the older and equivalent

Global shared resources (hwpipes, hwmixers and SMP) for MDP5 are

Re-spin of Archit's original RFC. I've added a modeset lock to the
private object, making it operate in a way more consistent with other
objects, and avoiding the need for the locking dance in the driver.
Possibly we could split up mixer state from smp/hwpipe state into
separate private objects.
Follow the same pattern of locking as with other state objects. This
avoids boilerplate in the driver.

These bindings allow to describe most known standard USB connectors
and it should be possible to extend it if necessary.
USB connectors, beside USB can be used to route other protocols,
for example UART, Audio, MHL. In such case every device passing data
through the connector should have appropriat
Hi,
Thanks for reviews of previous iterations.
This patchset introduces USB physical connector bindings, together with
working example.
I have removed RFC prefix - the patchset seems to be heading
to a happy end :)
v4: improved binding descriptions, added missing reg in dts.
v3: Separate binding
Samsung micro-USB 11-pin connector beside standard micro-USB pins,
has pins dedicated to route MHL traffic.

Does this problem also happen using xf86-video-amdgpu instead of the
modesetting driver with Xorg?

Calling request_irq() followed by disable_irq() is usually a bad idea,
specially if the interrupt can be pending, and you're not yet in a
position to handle it.
This is exactly what happens on my kevin system when rebooting in a
second kernel using kexec: Some interrupt is left pending from

The rockchip DRM driver is quite careful to disable interrupts
when taking a lock that is also taken in interrupt context,
which is a good thing.
What is a bit over the top is to use spin_lock_irqsave when

interrupt again, and disabling inte

The main issue is that the vop driver expects the interrupts to be
cleared and disabled when booting. N

MMIO accessors should be used to access MMIO regions, preferably

Let's convert the bulk register copy to writel/readl_relaxed,
which is the correct API.
