dpu_plane_atomic_check() is a very thin wrapper around
dpu_plane_sspp_atomic_check(). All it does is a NULL-check of state->fb,
which is already done by drm_atomic_helper_check_plane_state(). Further,
the helper sets state->visible = false when this is true. So remove
dpu_plane_atomic_check() and just use dpu_plane_sspp_atomic_check()
directly.

src/dst rects are checked in both atomic_check and atomic_update, with
the more comprehensive check occurring in atomic_update, which is
backwards. So consolodate the checks in atomic_check.

RM maintained a redundant definition for display topology
to identify the no. of hw blocks needed for a display
and their hardware dependencies. This information can be
implicitly deduced from the msm_display_topology structure
available in RM reserve request. In addition to getting
rid of the redundant topology, this change also removes
the topology name enums and their usages.

The MDSS device is created before the MSM driver attempts to bind the
sub components. If any of the components return -EPROBE_DEFER the MDSS
device is destroyed and tried again later.
If this happens the dpu_mdss_isr interrupt created from the DPU MDSS
is not freed when the MDSS device is destroyed and has a risk of
triggering later and hitting a fault by accessing a mmio region that
no longer exists. Even if the interrupt isn't triggered by
accident when the device attempts to reprobe it would error out
when it tries to re-register the interrupt so unconditionally removing
it in the destroy is the right move.
Switch the device managed dpu_mdss_isr to be unmanaged and add a
free_irq() in the mdss destroy function.

The atomic_check is a bit too aggressive with respect to planes which
leave the active area. This caused a bunch of log spew when the cursor
got to the edge of the screen and stopped it from going all the way.
This patch removes the conservative bounds checks from atomic and clips
the dst rect such that we properly display planes which go off the
screen.
Changes in v2:
- Apply the clip to src as well (taking into account scaling)
Changes in v3:
- Use drm_atomic_helper_check_plane_state() to clip src/dst

Code: 910003fd 2a0403e6 eb0400ff 54000060 (38646845)
Looking at the code I see that drm_encoder_init() is called from the DPU
code with 'DRM_MODE_CONNECTOR_DSI' passed in as the 'encoder_type'
argument (follow from _dpu_kms_initialize_dsi()). That corresponds to
the integer 16. That is then indexed into drm_encoder_enum_list in
drm_encoder_init() to look up the name of the encoder. If you're still
following along, that's an encoder not a connector! We really want to
use DRM_MODE_ENCODER_DSI (integer 6) instead of DRM_MODE_CONNECTOR_DSI
here, or we'll go out of bounds of the encoder array. Pass the right
thing and everything is fine.

Currently msm_dsi->id is initialized to 0 during kzalloc. If bind fails
for a secondary dsi device before its id can be properly set (such as
during dt parsing), the id will point to the primary dsi device, causing
its reference to be removed from dsi_manager's global (msm_dsim_glb)
array.
This patch initializes the id to -1 and checks for negative in the
manager cleanup.

dma_fence_default_wait is the default now, same for the trivial
enable_signaling implementation.
v2: Also remove the relase hook, dma_fence_free is the default.

Add support for the A6XX family of Adreno GPUs. The biggest addition
is the GMU (Graphics Management Unit) which takes over most of the
power management of the GPU itself but in a ironic twist of fate
needs a goodly amount of management itself. Add support for the
A6XX core code, the GMU and the HFI (hardware firmware interface)
queue that the CPU uses to communicate with the GMU.

Failure to load firmware is the primary reason to fail adreno_load_gpu().
Try to load it first before going into the hardware initialization code and
unwinding it. This is important for a6xx because the GMU gets loaded from
the runtime power code and it is more costly to fail in that path because
of missing firmware.

Add a helper function to parse the clock names and set up
the bulk data so we can take advantage of the bulk clock
functions instead of rolling our own. This is added
as a helper function so the upcoming a6xx GMU code can
also take advantage of it.

In the quest to remove all stack VLA usage from the kernel[1], this
switches to using a kasprintf()ed buffer. Return paths are updated
to free the allocation.

Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.
Ref- commit 1c8f422059ae ("mm: change return type to vm_fault_t")
Previously vm_insert_mixed() returns err which driver
mapped into VM_FAULT_* type. The new function
vmf_insert_mixed() will replace this inefficiency by
returning VM_FAULT_* type.
vmf_error() is the newly introduce inline function
in 4.17-rc6.
