Re: [PATCH v1 4/4] drm/mediatek: add mt8195 hdmi TX support

Hi, Guillaume:

This is a big patch, and I'm not familiar with this driver, so the
review process would be long. So I tell you about how I review this
patch, and if you could process according to my way, the process would
be more short.

1. Find the common part of all hdmi driver.
Even though mt8195 hdmi has many difference with other mediatek soc
hdmi driver, I would like to find the common part and have just one
copy of the common part. I expect there would three file finally:

mtk_hdmi.c               (the common part)
mtk_hdmi_mt8173.c (each soc special part)
mtk_hdmi_mt8195.c (each soc special part)

But this would be difficult in this stage, so you could temporarily
have these three file:

mtk_hdmi_common.c (the common part)
mtk_hdmi.c                 (each soc special part)
mtk_hdmi_mt8195.c   (each soc special part)

When review is almost done, then change the file name as I wish.

2. The first patch has only basic function, separate advance function
to another patch.
When comparing mt8195 hdmi driver with other hdmi driver, if mt8195
hdmi driver has some function that other hdmi does not have, I would
think that function is advance function and should be separate to
another patch.

If you follow this way, I think the review process would be short.
Because this patch is big, I would just review partial part each time.

Regards,
Chun-Kuang.
