Subject: [PATCH v2 0/3] Initial driver support for Xilinx M2M Video Scaler
Date: Wed, 21 Feb 2018 14:43:13 -0800	[thread overview]
Message-ID: <1519252996-787-1-git-send-email-rohit.athavale@xilinx.com> (raw)

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
