[PATCH V4 02/11] soc: mediatek: PMIC wrap: don't duplicate the wrapper data

[John Crispin]

As we add support for more devices struct pmic_wrapper_type will grow and
we do not really want to start duplicating all the elements in
struct pmic_wrapper.

[PATCH V4 08/11] soc: mediatek: PMIC wrap: remove pwrap_is_mt8135() and pwrap_is_mt8173()

[John Crispin]

With more SoCs being added the list of helper functions like these would
grow. While at it also add a new flag "has_bridge" and use that instead of
pwrap_is_mt8173() where appropriate.

Changed in V4
* fix 2 typos in the description

[PATCH V4 08/11] soc: mediatek: PMIC wrap: remove pwrap_is_mt8135() and pwrap_is_mt8173()

[John Crispin]

With more SoCs being added the list of helper functions like these would
grow. While at it also add a new flag "has_bridge" and use that instead of
pwrap_is_mt8173() where appropriate.

Hi Henry,

i stumbled across this aswell. however this DEW access is direct using
pwrap_writel() and not indirect pwrap_write(). hence this is correct.
the DEW wrapper only exists for pwrap_write() style access. this might
have been a bug in the original commit.

this patch however keeps the functionality as is.

Hi Henry,

i stumbled across this aswell. however this DEW access is direct using
pwrap_writel() and not indirect pwrap_write(). hence this is correct.
the DEW wrapper only exists for pwrap_write() style access. this might
have been a bug in the original commit.

this patch however keeps the functionality as is.

Hi John,

Oh. Sorry, there is no need to change, I just mixed up the parameter
val/reg of pwrap_writel() of this line.
Please keep original code, thanks.

Would it make sense to document the pmic_wrapper_type struct so that in, 
lets say, half a year it will be easier to remember what every member is

So mt2701 can be used with both PMICs? Just wondering, as from what I 
know, SoC and PMIC a tightly coupled.

In general this series looks quite good to me.

yes, it can be run with old and new style pmics. this is why the MAN_CMD
SPI_W bit has changed. the old BIT(13) is used to tell the wrapper what
slave type it has.

there is a way to runtime set the pmic but there is still a detail i
need to look at so it is not part of this series

i'll spin V5 during the day. busy adding dual gmac support to the
ethernet driver just now.
