[PATCH 8/9] ARM: dts: exynos: Use macros for GPIO configuration on exynos5410

Krzysztof Kozlowski k.kozlowski at samsung.com
Wed Aug 31 05:13:32 PDT 2016


Usage of DTS macros instead of hard-coded numbers makes code easier to
read.  One does not have to remember which value means pull-up/down or
specific driver strength.
