This series adds a binding and the corresponding V4L subdev driver for
the TI SCAN921226H video deserializer. Although the device doesn't need
to be configured, it can be controlled via GPIOs to allow multiple
sensors on the same parallel video bus.
Jan Luebbe (2):
media: dt-bindings: add
the parallel bus. By enabling only one at a time,
a camera can be selected at runtime using mediactl.
This driver will en-/disable the deserializer via GPIOs as needed
depending on the media entity link state.
The current v4l2-compliance doesn't report any warnings or errors.

Now when the usage of get_user_pages() in media drivers got cleaned up, here
comes a series which removes knowledge about mmap_sem from a couple of other
drivers. Patches are trivial and standalone but please check, they are only

Conversion to the use of pinned pfns made some functions unused. Remove
them. Also there's no need to lock mmap_sem in __buf_prepare() anymore.

Convert g2d_userptr_get_dma_addr() to pin pages using get_vaddr_frames().
This removes the knowledge about vmas and mmap_sem locking from exynos
driver. Also it fixes a problem that the function has been mapping user
provided address without holding mmap_sem.

Provide simple helper functions to map virtual address range into an
array of pfns / pages.

Convert vb2_vmalloc_get_userptr() to use frame vector infrastructure.
When we are doing that there's no need to allocate page array and some
code can be simplified.

Hello,
Sorry for a quick resend but the missing vmalloc include in mm/gup.c is
annoying for archs that need it and I was also told to extend CC list a bit.
I'm sending the fourth version of my patch series to abstract vma handling
from the various media drivers. After this patch set drivers
Convert vb2_dc_get_userptr() to use frame vector infrastructure. When we

belongs to VM_IO | VM_PFNMAP vma, we don't touch page structures. Caller
must make sure pfns aren't reused for anything else while he is using
them.
This function is created for various drivers to simplify handling of
their buffers.
