[PATCH v2 0/6] Fix tvp5150 regression with em28xx

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

This patch series fixes a regression reported by Devin Heitmueller that
affects a large number of em28xx. The problem was introduced by

commit 13d52fe40f1f7bbad49128e8ee6a2fe5e13dd18d

    [media] em28xx: fix implementation of s_stream

that started calling s_stream(1) in the em28xx driver when enabling the
stream, resulting in the tvp5150 s_stream() operation writing several
registers with values fit for other platforms (namely OMAP3, possibly others)
but not for em28xx.

The series starts with two unrelated drive-by cleanups and an unrelated bug
fix. It then continues with a patch to remove an unneeded and armful call to
tvp5150_reset() when getting the format from the subdevice (4/6), an update of
an invalid comment and the addition of macros for register bits in order to
make the code more readable (5/6) and actually allow following the incorrect
code flow, and finally a rework of the s_stream() operation to fix the
problem.

Compared to v1,

- Patch 4/5 now calls tvp5150_reset() at probe time
- Patch 5/6 is fixed with an extra ~ removed

I haven't been able to test this with an em28xx device as I don't own any that
contains a tvp5150, but Mauro reported that the series fixes the issue with
his device.

I also haven't been able to test anything on an OMAP3 platform, as the tvp5150
driver go broken on DT-based systems by
