[PATCH 0/4] ARM: multi_v7_defconfig: Stuff for Exynos

[Krzysztof Kozlowski]

Dear Kukjin,

The patchset enables various config options on multi_v7 config
for Exynos boards. The first two patches are actually resend.

Arnd suggested [0] that this can go through your tree.

Patchset is rebased on next-20150515 and Javier's patchset [1]
(to avoid conflicts around regulators and clocks).

Please let me know if this should be rebased on other commit.

Best regards,
Krzysztof

[PATCH 1/4] ARM: multi_v7_defconfig: Enable CPU idle for Exynos

[Krzysztof Kozlowski]

From: Krzysztof Kozlowski <k.kozlowski@samsung.com>

Current Exynos CPU idle driver supports entering AFTR (Arm Off, Top
Running) mode on Exynos3250, Exynos4210 (coupled), Exynos4x12 and
Exynos5250. Enable it in default configuration to reduce energy
consumption.

[PATCH 2/4] ARM: multi_v7_defconfig: Enable PMIC and MUIC drivers for Exynos boards

[Krzysztof Kozlowski]

From: Krzysztof Kozlowski <k.kozlowski@samsung.com>

Enable drivers for PMICs and MUICs present on Exynos-based devices:
 - max14577: charger, fuel gauge (max17040), regulator,
   used on: Gear 1, Gear 2,
 - max7693: charger, fuel gauge (max17042),
   used on: Trats2,
 - s5m/s2mps: RTC, clock,
   used on: Arndale, Arndale Octa, Gear 1, Gear 2

This allows full usage of charging stack on these devices along with RTC
and 32 kHz clocks.

The I2C_GPIO is necessary for MAX77693 on Trats2 because the device is
wired to Exynos4412 over GPIO.

On a first look, I agree with all the Kconfig symbols but I noticed that
you are adding them to be built-in while the current policy for multi_v7
is to build as much as possible as a module.

Could you please add as =m for all the tristate symbols that can be build
as a module?

Best regards,
Javier

Your request makes sense. For many Exynos boards we got used to
compiling it into the kernel, not as a module, but I think only reason
behind this is convenience. I'll try to switch to modules.

Krzysztof
