[RESEND PATCH v3 0/6] media: staging: rkisp1: bugs fixes and vars renames

[Dafna Hirschfeld]

RESEND the patchset because I forgot to add the first two patches
to the set (now also dropping CC to stable)

The first two patches in this patchset are two bug fixes related to the enumeration and
settings of the sink format of the resizer entity.
The next 3 patches are renaming/removing macros and variables.
patch 6 adds documentation to the struct rkisp1_isp_mbus_info

changes from v2:
- patch 3 is new - remove macro RKISP1_DIR_SINK_SRC since the code is more readable without it.
- patch 5 - rename 'direction' to 'isp_pads_mask' instead of 'isp_pads_flags'
- patch 6 is new - add documentation of the struct 'rkisp1_isp_mbus_info'

changes from v1:
- added "Fixes: 56e3b29f9f6b "media: staging: rkisp1: add streaming paths"
to the commit log of the first two patches.
- added two patches. One patch rename the macros "RKISP1_DIR_*"
to "RKISP1_ISP_SD_*", another that rename the field 'direction'
in 'struct rkisp1_isp_mbus_info' to 'isp_pads_flags'

[RESEND PATCH v3 1/6] media: staging: rkisp1: rsz: supported formats are the isp's src formats, not sink formats

[Dafna Hirschfeld]

The rkisp1_resizer's enum callback 'rkisp1_rsz_enum_mbus_code'
calls the enum callback of the 'rkisp1_isp' on it's video sink pad.
This is a bug, the resizer should support the same formats
supported by the 'rkisp1_isp' on the source pad (not the sink pad).

[RESEND PATCH v3 2/6] media: staging: rkisp1: rsz: set default format if the given format is not RKISP1_DIR_SRC

[Dafna Hirschfeld]

When setting the sink format of the 'rkisp1_resizer'
the format should be supported by 'rkisp1_isp' on
the video source pad. This patch checks this condition
and set the format to default if the condition is false.

[RESEND PATCH v3 3/6] media: staging: rkisp1: remove macro RKISP1_DIR_SINK_SRC

[Dafna Hirschfeld]

The macro RKISP1_DIR_SINK_SRC is a mask of two flags.
The macro hides the fact that it's a mask and the code
is actually more clear if we replace it the with bitwise-or explicitly.

[RESEND PATCH v3 5/6] media: staging: rkisp1: rename the field 'direction' in 'rkisp1_isp_mbus_info' to 'isp_pads_mask'

[Dafna Hirschfeld]

The field 'direction' in 'struct rkisp1_isp_mbus_info' is a mask
of the supported pads of the mbus code. Therefore
the name 'isp_pads_mask' is better.
The patch also rename a local variable 'dir' that holds such mask
to 'pad'.

I just saw you submitted the change in a separated patch.

I would submit patch 4/6 before this one.

Could you submit this change before 2/4? So when you move the macro, it will be correct already.

Re: [RESEND PATCH v3 5/6] media: staging: rkisp1: rename the field 'direction' in 'rkisp1_isp_mbus_info' to 'isp_pads_mask'

[Helen Koike]

Hi Dafna,

Thank you for the patch.

On 6/13/20 6:13 AM, Dafna Hirschfeld wrote:

tbh, I'm not sure if it is better, since it feels it masks pads.

Also, the isp prefix is not required, since it is already inside rkisp1_isp_formats[].

My opinion is that the name "direction" make sense.

Or maybe some other name that reflects which pads the format applies to, but tbh
I think the current one is fine.

Regards,
Helen

[RESEND PATCH v3 4/6] media: staging: rkisp1: rename macros 'RKISP1_DIR_*' to 'RKISP1_ISP_SD_*'

[Dafna Hirschfeld]

The macros 'RKISP1_DIR_*' are flags that indicate on which
pads of the isp subdevice the media bus code is supported. so the
prefix RKISP1_ISP_SD_ is better.
