Subject: [PATCH 0/2] pinctrl: samsung: Split per ARMv7/v8 arch

Hi,

There will not be a shared image between ARMv7 and ARMv8 so there is no need to
combine all of this into one driver.

Splitting the data allows to make it more granular (e.g. code related to
ARMv8 Exynos is self-contained), slightly speed up the compilation and
reduce the effective size of compiled kernel.

Diff of second patch is not nice... but it is the best I created.
Experimenting with -B and -M resulted in detection of copy/rename but end
diff was 60% bigger in lines of patch.

Tests on ARMv8 would be much appreciated.


Best regards,
Krzysztof
