[PATCH RESEND 0/2] mfd: twl6040: bulk access fix and pdmclk registration

[PATCH RESEND 0/2] mfd: twl6040: bulk access fix and pdmclk registration

[Peter Ujfalusi]

Hi,

The two patch were part of a bigger series to support the external pdmclk clock
needed by the McPDM on OMAP4/5 [1].

The other patches have been applied, but the ASoC patch to actually use the
pdmclk needed to be reverted as the MFD parts were not taken.

Regards,
Peter

[PATCH RESEND 1/2] mfd: twl6040: The chip does not support bulk access

[Peter Ujfalusi]

Bulk access is not working with twl6040, we need to use single register
access. Bulk access would happen when we try to sync the regcache after
power on.

[PATCH RESEND 2/2] mfd: twl6040: Register child device for twl6040-pdmclk

[Peter Ujfalusi]

The McPDM in OMAP4/5 is using the pdmclk from twl6040 as functional clock.
The twl6040-pdmclk driver provides a clock which can be used to make sure
that the pdmclk is active when the McPDM is in use.

What an awful way of adding cells.

That wouldn't happen in my day! ;)

But ... it fits in with the current way of doing things, so:

Lee, for some reason this patch is not found in linux-next (20160927). I can
see patch 1, but this one is missing.
