Subject: [PATCH 1/1] ARM: exynos_defconfig: Enable max77802 rtc and clock drivers

Commit 6e80e3d87549 ("ARM: exynos_defconfig: Enable MAX77802")
enabled support for the max77802 regulators but the PMIC also
has a Real-Time-Clock (RTC) and 2-channel 32kHz clock outputs.

Enable the kernel config options to have the drivers for these
devices built-in since they are present in many Exynos boards.

This patch supersedes [0] since commit "ARM: exynos_defconfig: savedefconfig"
is not present in linux-next anymore which disabled among other options, the
max77802 support.

However, support for the max77802 rtc and clocks were not enabled on exynos
defconfig so $subject is still needed.

Kevin, I carried your tags from [0] since $subject enables the options you
needed to get RTC wakeup from suspend working on exynos5800-peach-pi. Please
let me know if they no longer applies.

Best regards,
Javier
