Please do not roll your own MACROS like this. If they are helpful for
you, they are likely to be helpful for others. However, this is your
lucky day, as we've been here before. Please rebase onto the MFD tree
where you will find some pre-authored macros which aren't too
dissimilar to this one. Please use one of those instead.

If you use .probe_new (see below) you can omit the 'id' param.

Do this above the check, then do

Why do we need to make a copy of it?

We already know the name. Why do we need to do this dynamically?

We already saved ddata. Why do we need to save it here as well?

This doesn't look right to me.

consider of using mutiple mt6360 chips, we can seperate diff i2c
irq_chip.name by device_name originally
but we can't find silimar case by overview other mfd driver
we will delete this

According to our architecture as attachment,
mt6360 have 4 i2c slave address for different parts
so we set whole register table in mt6360-private.h, it will be
included by other modules
we will delete it next patch
and we will add until we use it

Hi Lee,
we find OF_MFD_CELL is not defined in mfd/core.h, which is ready to
merge to next kernel version
https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next-history/+/master/Next/merge.log
may i ask how can i upstream without this definition?
e.g. we pull this patch and build pass, new patch without add macro define

I thought i need to wait this "mfd/for-mfd-next" patch merge to latest
codebase, but we can't actually get the date or version (e.g. Linux
5.4-rc4) landing
and i try command "git merge mfd/for-mfd-next" which also can't work
may i ask how to pull this patch for temporarily build pass?
>> may i ask how can i upstream without this definition?
