[PATCH 0/5] mfd: sec-core: Add support S2MPS13 PMIC device

[Chanwoo Choi]

This patchset adds Samsung S2MPS13 PMIC device driver in existing S2MPS11 PMIC
driver. The S2MPS13 has just the differnet number of regulator from existing
S2MPS14 PMIC and RTC/CLOCK IP of S2MPS13 is the same with S2MPS14. S2MPS13
PMIC has LDO[1-40] and BUCK[1-10] regulators.

[PATCH 1/5] mfd: sec-core: Add support for S2MPS13 device

[Chanwoo Choi]

This patch adds the support for Samsung S2MPS13 PMIC device to the sec-core MFD
driver. The S2MPS13 is very similar with existing S2MPS14 and includes PMIC/
RTC/CLOCK devices.

If you have to resubmit this for any reason, I'd like the one liners
on one single line (curly braces and all).

But for now, for my reference:

OK, I'll modify it as following:

static const struct mfd_cell s2mps13_devs[] = {
	{ .name = "s2mps13-pmic", },
	{ .name = "s2mps13-rtc", },
	{
		.name = "s2mps13-clk",
		.of_compatible = "samsung,s2mps13-clk",
	},
};

Chanwoo Choi

[PATCH 2/5] regulator: s2mps11: Add support S2MPS13 regulator device

[Chanwoo Choi]

This patch adds S2MPS13 regulator device to existing S2MPS11 device driver.
The S2MPS13 has just different number of regulators from S2MPS14.
The S2MPS13 regulator device includes LDO[1-40] and BUCK[1-10].

The header file(linux/mfd/samsung/s2mps13.h) is used in this patch(2/5).
But, First patch(1/5) don't use some definitions in header file.

[PATCH 3/5] clk: s2mps11: Add the support for S2MPS13 PMIC clock

[Chanwoo Choi]

This patch adds the support for S2MPS13 PMIC clock which is same with existing
S2MPS14 RTC IP. But, S2MPS13 uses all of clocks (32khz_{ap|bt|cp}).

The patch looks corrupted here. Missing '+'?

Rest looks fine.

The RTC block looks exactly the same as S2MPS14. I wonder can S2MPS13 be
supported without adding all "+ case S2MPS13X:" here? Maybe pass the
same ID in s5m_rtc_id? This would reduce number of changes to only one line.

Best regards,
Krzysztof

I tried to use S2MPS14x type without adding S2MPS13X.
But, there are two method to probe RTC driver probe.
First, as you comment, use s5m_rtc_id (in drivers/rtc/rtc-s5m.c) to probe S2MPS13 RTC.
Second, register mfd devcies for s2mps13 RTC(in drivers/mfd/sec-core.c) to probe S2MPS13 RTC.

We could support S2MPS13 RTC to modify s5m_rtc_id table in first case as you comment,
But, We could not support S2MPS13 RTC in second case because S2MPS13 is different from S2MPS14
and S2MPS13 must have other type form existing S2MPS14x type.

Chanwoo Choi

What's the relation of S2MPS14 RTC and clock driver?

I checked the difference between S2MPS13 and S2MPS14.
But, all register (RTC) of both PMICs was the same completely.
So, I just add S2MPS13 type to use existing S2MPS14 RTC feature for S2MPS13 RTC.

Okay, so it looks like this requires another submission.  Please add
the fixup I requested in the first patch.

[PATCH 5/5] mfd: s2mps11: Add binding documentation for Samsung S2MPS13 PMIC

[Chanwoo Choi]

This patch adds the binding documentation for Samsung S2MPS13 PMIC
which is similiar with existing S2MPS14 PMIC. S2MPS13 has the different number
of regulators from S2MPS14 and RTC/Clock is the same with the S2MPS14.
