TVP514x Driver with Review comments fixed
From: Vaibhav Hiremath <hvaibhav@ti.com>
I have fixed most of the review comments received so far.
Here are the details:
FIXES
Wrong use of CONFIG_VIDEO_ADV_DEBUG option:
Implemented module parameter based approach for debugging.
Bridge driver and access to TVP registers:
The bridge driver will now provide only neccessary information
depending on platform/board/interface. In case of TVP5146, we do
require clk_polarity, input, number of input, HS/VS polarity, etc..
which is interface dependent.
All register access and values are limited to TVP driver.
V4L2-int framework:
The new sub-device framework is a new development and will take its
own time to mature and stabilize. The implementation is rightly
placed in a different branch for the same reason.
I beleive till this time, we should move ahead with current framework.
This patch provides base for V4L2-int capture-master driver and patch
for the same will be posted in couple of weeks. we are in the process
of code clean-up.
It would be good if we can get this patch into the current codebase
till the 'sub-device' framework stabilizes. The migration can be
planned immediately.
i2c table:
Specified the name of chip.
Code cleanup:
Multiple changes as suggested.
PENDING (TO DO)
I2C Legacy framework support:
Still no change for Legacy support (Hans agreed on this).
Can be added while we move to sub-device framework.
New sub-device framework support:
Will be taken up immediately.
