Subject: [PATCH] arm64: dts: fsd: fix drive strength macros as per FSD HW UM
[ Upstream commit 574d6c59daefb51729b0640465f007f6c9600358 ]
Drive strength macros defined for FSD platform is not reflecting actual
names and values as per HW UM. FSD SoC pinctrl has following four levels
of drive-strength and their corresponding values:
Level-1 <-> 0
Level-2 <-> 1
Level-4 <-> 2
Level-6 <-> 3
The commit 684dac402f21 ("arm64: dts: fsd: Add initial pinctrl support")
used drive strength macros defined for Exynos4 SoC family. For some IPs
the macros values of Exynos4 matched and worked well, but Exynos4 SoC
family drive-strength (names and values) is not exactly matching with
FSD SoC.
Fix the drive strength macros to reflect actual names and values given
in FSD HW UM.
