This patch series has three commits :
- Driver support for the Xilinx M2M Video Scaler IP
- TODO document
- DT binding doc
Changes in HW register map is expected as the IP undergoes changes.
This is a first attempt at the driver as an early prototype.
This is a M2M Video Scaler IP that uses polyphases filters to perform
video scaling. The driver will be used by an application like a
gstreamer plugin.
Change Log:
v2
- Cc'ing linux-media mailing list as suggested by Dan Carpenter.
Dan wanted to see if someone from linux-media can review the
driver interface in xm2m_vscale.c to see if it makes sense.
- Another question would be the right place to keep the driver,
in drivers/staging/media or drivers/staging/
- Dropped empty mmap_open, mmap_close ops.
- Removed incorrect DMA_SHARED_BUFFER select from Kconfig
v1 - Initial version
