Implement a memory provider that allocates dmabuf devmem in the form of

The provider receives a reference to the struct netdev_dmabuf_binding

The provider obtains a reference on the

Abstrace the memory type from the page_pool so we can later add support

Description: OpenPGP digital signature
The conditional was supposed to prevent enabling of a crtc state
without a set primary plane. Accidently it also prevented disabling
crtc state with a set primary plane. Neither is correct.
Fix the conditional and just driver-warn when a crtc state has been
enabled without a primary plane which
The table of primary plane formats wasn't sorted at all, leading to
applications picking our least desirable formats by defaults.
Sort the primary plane formats according to our order of preference.

preferred format is a 32bpp
vmwgfx never supported prime import of external buffers. Furthermore the

By default vmwgfx doesn't support vblanking or crc generation which

1. The devm_drm_dev_alloc() function returns error pointers.
Update the error handling to check for error pointers instead of NULL.
2. Currently panthor_vm_get_heap_pool() returns both ERR_PTR() and
NULL(when create is false and if there is no poool attached to the
VM)

Currently modetest supports only the YUV420 and YVU420 planar YCbCr
plane formats (aka YV12 and YU12). Extend the code to add support for
YUV422 / YVU422 and YUV444 / YVU444 plane formats.

Daniel.
On some HW designs, it's easier for the layout if the P/N pins are swapped.
The driver currently has a DT property to do that.
This change documents the 'lontium,pn-swap' property.

On some HW designs, it's easier for the layout if the P/N pins are swapped.
In those cases, we need to adjust (for this) by configuring the MIPI analog
registers differently. Specifically, register 0x3e needs to be 0xf6
(instead of 0xd6).
This change adds a 'lontium,pn-swap' device-tree property

ivpu_device->context_xa is locked both in kernel thread and IRQ context.
It requires XA_FLAGS_LOCK_IRQ flag to be passed during initialization
otherwise the lock could be acquired from a thread and interrupted by
an IRQ that locks it for the second time causing the deadlock.
This deadlock was
Change "VPU" to "NPU" in ivpu_suspend() so it matches all other error
messages.
