[PATCH 0/3] ARM: Enable NTC Thermistors and max77802 regulator drivers

[Javier Martinez Canillas]

Hello Kukjin and Krzysztof,

This series enables support in exynos_defconfig and multi_v7_defconfig
for the NTC Thermistors found on the Exynos5 Peach Chromebooks and
also enables support for the max77802 regulators in multi_v7_defconfig.

The series is composed of the following patches:


Javier Martinez Canillas (3):
  ARM: multi_v7_defconfig: Enable max77802 regulator
  ARM: multi_v7_defconfig: Enable NTC Thermistors support
  ARM: exynos_defconfig: Enable NTC Thermistors support

[PATCH 1/3] ARM: multi_v7_defconfig: Enable max77802 regulator

[Javier Martinez Canillas]

The Maxim max77802 Power Management IC has besides other devices, a set of
regulators. Commit f3caa529c6f5 ("ARM: multi_v7_defconfig: Enable max77802
regulator, rtc and clock drivers") was supposed to enable the config option
for the regulator driver as a module but the final version that landed did
not include this. So this patch enables the needed Kconfig option.

Please describe why do you want to enable it (IOW who will benefit from
enabling it?). This symbol was removed by Kukjin from your commit:
	[kgene at kernel.org: removing useless REGULATOR_MAX77802 config]
so justification would be welcomed.

Beside the commit description I agree with the patch.

Best regards,
Krzysztof

You are right, sorry for not making the commit message clear. This PMIC
is used by a couple of Exynos5 based boars such as the Peach Pit and Pi
Chromebooks. I expect it to be found in other designs too just like the
max77686 is found in many Exynos5 based boards.

I'll add this to the commit message on v2.

Does this mean I can add your Reviewed-by to this patch as well?

With extended description (something similar to explanation in your
other patches) yes, go ahead:
