[PATCH v4 00/21] media: rkisp1: Misc bug fixes and cleanups

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

 



Hello,

This series fixes multiple issues and performs further cleanups for the
rkisp1 driver.

Patches 01/21 to 07/21 fix issues in the error paths at probe time that
lead to kernel crashes in case of errors. The .remove() path is also
improved as a result.

Patches 08/21 and 09/21 then clean up register definitions, patch 10/21
swaps the arguments to rkisp1_write(), and patch 11/21 simplifies access
to the resizer registers.

Patches 12/21 to 18/21 move on to improving debugfs support, with code
first moved to a separate file (12/21) that can be conditionally
compiled (13/21), support for collecting statistics on the input
interface (14/21, very useful to check if the ISP actually receives
data) and for dumping core and ISP registers (15/21). Patch 16/21
continues that rework by moving the resizer register dumps support to
debugfs too, and patch 17/21 consolidates the resizer dumps code with
the core and ISP. Patch 18/21 completes the work by making the register
name length dynamic.

Finally, patch 19/21 simplifies the V4L2 querycap implementation on
video nodes, and patches 20/21 and 21/21 fix alignment and indentation.

More fixes and improvements should follow, so I'd like to merge sooner
than latter if possible, to avoid having to rebase large series.
