Also the IPs are not using the default drive strength values as recommended by 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. The intention of this patch series is to: 1. Fix the drive strength macros to reflect actual names and values given in FSD HW UM. 2. Ensure that the existing peripherals in device tree file is using default drive strength values recommended in FSD HW UM.
