to http://linuxtv.org/hg/v4l-dvb master development tree.
Kernel patches in this development tree may be modified to be backward
compatible with older kernels. Compatibility modifications will be
removed before inclusion into the mainstream Kernel

From: Muralidharan Karicheri <m-kariche...@ti.com>
vpfe-capture - converting dm355 ccdc driver to a platform driver
1) clocks are configured using generic clock names;
2) converts the driver to a platform driver;
3) cleanup - consolidate all static variables inside a structure, ccdc_cfg;
The ccdc now uses a generic name for clocks. "master" and "slave". On
individual platforms
these clocks will inherit from the platform specific clock. This will allow
re-use of
the driver for the same IP across different SoCs.
Updated based on Kevin's comments on clock configuration and error code (v3,
v4).
