[PATCH V3 00/11] soc: mediatek: PMIC wrap: add MT6323/2701/7623 support

[PATCH V3 00/11] soc: mediatek: PMIC wrap: add MT6323/2701/7623 support

[John Crispin]

Changes in V3:
* I accidentially sent a V2 about 15 minutes ago. Unfortunatley the time
  inside the VM that i used was wrong and lagged by 6 days. V3 is the same
  as V2 but with the correct time.

Changes in V2:
* rebase the code on the MTK internal driver

John Crispin (11):
  dt-bindings: ARM: Mediatek: add MT2701/7623 string to the PMIC
    wrapper doc
  soc: mediatek: PMIC wrap: don't duplicate the wrapper data
  soc: mediatek: PMIC wrap: add wrapper callbacks for init_reg_clock
  soc: mediatek: PMIC wrap: split SoC specific init into callback

    MT2701/7623
  soc: mediatek: PMIC wrap:: SPI_WRITE needs a different bitmask for

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 V3 08/11] soc: mediatek: PMIC wrap: remove pwrap_is_mt8135() and pwrap_is_mt8173()

[John Crispin]

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

[PATCH V3 09/11] soc: mediatek: PMIC wrap: add a slave specific struct

[John Crispin]

This patch adds a new struct pwrap_slv_type that we use to store the slave
specific data. The patch adds 2 new helper functions to access the dew
registers. The slave type is looked up via the wrappers child node.

[PATCH V3 09/11] soc: mediatek: PMIC wrap: add a slave specific struct

[John Crispin]

This patch adds a new struct pwrap_slv_type that we use to store the slave
specific data. The patch adds 2 new helper functions to access the dew
registers. The slave type is looked up via the wrappers child node.

[PATCH V3 10/11] soc: mediatek: PMIC wrap: add mt6323 slave support

[John Crispin]

Add support for MT6323 slaves. This PMIC can be found on MT2701 and MT7623
EVB. The only function that we need to touch is pwrap_init_cipher().

For PWRAP_MT8173_DEW_*, since they exist on pmic mt6397, it seems
strange to name them with MT8173 name. I guess we got this name because
MTK internal code base try to support them in MT8173.

On the other hand, these are not used in current code, maybe we can just
remove them?

strange to name them with MT8173 name. I guess we got this name because
MTK internal code base try to support them in MT8173.

On the other hand, these are not used in current code, maybe we can just
remove them?

I would prefer to use pwrap_[read,write] directly instead of adding 
another indirection.

has_bridge was introduced by this patch, but you don't set it explicitly 
to 0 in pwrap_mt8173.

Just as I see it, please try to write a summary to every new version of 
a patch set which explains what you changed between one version and 
another. This will help a lot making the review easier.

Thanks,
Matthias

You missed the "to zero" part before. now the comment makes sense. I can
set it to 0 if it is more obvious for you in that case.

general consent is to not declare statics to 0. check_patch.pl will
actually complain about those declarations. that is why i was confused.

If that's the case, then we accept the authority of check_patch.pl ;)
I didn't know that, so just leave has_bridge as it was.

I believe checkpatch only complain for global/static variables
initializers, not inside a struct initializers even when they are
global.

In MTK i2c drivers drivers/i2c/busses/i2c-mt65xx.c, we always explicitly
init flags in compatible struct, IMHO it make support feature for each
IC more clearly. This does not trigger any warning from checkpatch.

Ok, thanks for clarification.
