[PATCH 0/2] Remove SEC S5M MFDs with no compatibles

[David Virag]

The S5M8751 and S5M8763 MFD PMICs have no compatibles, and board file
support for them was removed, resulting in essentially no way for these
chips to be used anymore (unless they get dt compatibles).
They seemingly have never been in any board files upstream and I only
found references to the SM8751 being on the SMDK6450 board (which has
been unsupported for many years now) in a downstream Samsung Galaxy S2
kernel tree.

The patches should be applied in order.

[PATCH 1/2] mfd: sec: Remove PMICs without compatibles

[David Virag]

The S5M8751 and S5M8763 PMIC chips have no corresponding compatible
values, so since board file support was removed for this driver, there
is no way to specify these PMICs as present in boards anymore.
Remove leftovers of these chips since it's dead code.

[PATCH 2/2] rtc: s5m: Drop S5M8763 support

[David Virag]

The S5M8763 MFD has no device tree compatible, and since board file
support for it was removed, there's no way to use this MFD. After
removing the remaining code for it from the MFD driver, also remove
support for it in the s5m RTC driver, and all remaining references to
it.

Dropping it in the first patch would lead to build errors in the RTC
driver, so I do it in the second patch, but I see that you already
realized this in the 2nd reply.

Actually, looks like this should probably go in via MFD, so I need an
RTC Ack.

There were comments on 1/2 so I was expecting a v2.

Krzysztof commented there about the removal of an enum value that's
actually removed in 2/2 since it would break the RTC driver if it was
removed in 1/2. He realised that and corrected himself. No need for v2
AFAIK, unless something else is found.

The patch should definitely go via one tree (or by waiting for it to be
merged upstream, I guess) since the order has to be kept.

David
