Now that mxsfb has functional runtime_pm support we can enable power
gating for the DISPLAY power domain on imx6sx.
Since pci-imx doesn't support runtime power gating this is still
always-on unless PCI is disabled/unused. But it's reasonable for an imx

rocminfo reports both the CPU and the GPU.
If OpenCL can't use the CPU as a compute device, that's probably a limitation
of the OpenCL implementation.

sure, if I got the API right.
In userspace I create a bo and get a fd.
bo = gbm_bo_create(gbm, w, h, GBM_FORMAT_ARGB, GBM_BO_USE_LINEAR);
dmabuf_fd = gbm_bo_get_fd(bo);
Then I pass the fd to the grabber driver.

Add the Rockchip-sepcific dual-dsi setup and hook it into the VOP as well.
As described in the general dual-dsi devicetree binding, the panel should
define two input ports and point each of them to one of the used dsi-
controllers, as well as declare one of them as clock-master.
This is used to det
Right now the host is only unregistered when the driver is used via the
bridge api and not via the component api, leading to the host staying
registered in cases like probe deferral.
So move the host unregister to the general remove function, so that it
gets cleaned up in all cases.

The Rockchip DSI driver was separate till now, not using the common

With the regular means of adding the dsi-component in probe it creates
a race condition with the panel probing, as the panel device only gets

This patch hooks up the DRM gpu scheduler to the msm DRM driver. The
most noticeable changes to the driver are as follows. The submit path is
split into two parts, in the user context the submit(job) is created and
added to one of the entity's scheduler run queue. The scheduler then
tries to drain
The base scheduler patch has barebones timeout implementation, it does
not account for issues like starvation on lower priority rings. This
patch enables more accurate measurement on time spent on each
ringbuffer, thereby helping us with better timeout detection mechanism.

Add an optional backend function op which will let the scheduler clients
know when the timeout work got scheduled for a job. This will help
drivers with multiple schedulers(one per ring) measure time spent on the
ring accurately, eventually helping with better timeout detection.

With the introduction of the scheduler, most of the code related to
timeout detection, recovery and submission retirement are no longer
needed in the msm driver. This patch simply removes the no longer used
code.

In cases where the scheduler instance is used a base object of another
vendor driver object, it's not clear if the driver can call sched cleanup on
the fail path. Set the sched->thread to NULL, so that the vendor driver
can safely call drm_sched_fini() during cleanup.

The scheduler needs an instance name mostly for debug purposes. Save the
name in the ringbuffer instead of a stack variable, so that the name
can be shared with the scheduler.

Track the GPU fences created at submit time with idr instead of the ring
the sequence number. This helps with easily changing the underlying
fence to something we don't truly own, like the scheduler fence.
Also move the GPU fence allocation to msm_gpu_submit() and have
the function return the fenc
The submit path in msm_gpu_submit() takes a reference to the buffer
object and the iova. This should not be needed with a little bit of
code rearrangement. We still keep the same semantic of a valid GPU
submission holding a reference to the base object and the iova until
retirement.

When the scheduler comes into picture, the msm_gpu_submit() will be
called from the scheduler worker thread. So save the necessary information
into msm job structure for use at the actual GPU submission time. This
also simplifies the msm_gpu_submit() API.
