ARM: dts: Fix dm814x pinctrl address and mask (9621557f) · Commits · 戴 / test

Otherwise pinctrl won't work. Because of silicon errata for some dm814x versions, let's also keep bit 18 out of the function-mask and rely on the bootloader configuration for bit 18 as suggested by Matthijs van Duin <matthijsvanduin@gmail.com>. Devices with that need to use bit 18 can override the function-mask in the board specific dts file if really needed. Signed-off-by:
