Subject: [PATCH] ARM: multi_v7_defconfig: enable MAX77686 PMIC drivers for exynos4412-prime based SoCs
Date: Thu, 4 Dec 2014 13:24:24 -0800 [thread overview]
Message-ID: <1417728264-7268-1-git-send-email-tyler.baker@linaro.org> (raw)
This patch enables the MAX77686 PMIC drivers in the multi_v7_defconfig used
on exynos4412-prime family of SoCs [1]. The exynos4412-prime based boards
are producing the following runtime errors only on the multi_v7_defconfig [2]:
kern.err: deviceless supply vdd_arm not found, using dummy regulator
kern.err: exynos-cpufreq exynos-cpufreq: failed to set cpu voltage to 1287500
kern.err: cpufreq: __target_index: Failed to change cpu frequency: -22
I reviewed the exynos_defconfig, which does not produce these runtime
errors. It was obvious that the exynos_defconfig has the PMIC drivers
enabled, whereas the multi_v7_defconfig does not. This patch has been tested
on a odroid-u2 and a odroid-u3 board. It has resolved the runtime errors.
Therefore, I purpose we enabled these drivers in the multi_v7_defconfig.
