Subject[PATCH v2 1/5] drm/rockchip: vop: get rid of register init table
Message-ID<u2fgd-1TD-9@gated-at.bofh.it>
Register init table use un-document define, it is unreadable,
And sometimes we only want to update tiny bits, init table
method is not friendly, it's diffcult to reuse for difference
chips.

While I'm happy to see the init_table removed, it seems like the new code is not
equivalent to the old (ie: some register writes have been dropped). How did you
ensure that you're not breaking existing boards that depend on the deleted register
initialization?

Hi Sean

Some registers need to be initialized when vop power on, global_config_done, blank, win gate, etc.
Previously init_table was introduced to handle the initialization of these registers.

So, when we remove the init_table mechanism, we need to re-join the initialization of these registers,
this job is already done in this patch.

I think the title "get rid of" caused some doubts, it's not just remove init_table mechanism,
to be exact, direct setting needed register instead of handling with init_table.

I will make it cleaner next version.

Thanks.
