Merge tag 'samsung-dt-pinctrl-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/dt
Pull "Topic branch for Samsung DeviceTree cleanup for 4.9" from Krzysztof Kozłowski:
Replace in DT sources hard-coded values for pinctrl configuration like pull
up/down, drive strength and function. This makes the DTS easier to read,
especially that some drive strengths values are quite non-obvious.
