Some connectors are available directly on the module. This adds initial support, namely serial, USB, GMAC, eMMC, IR and TSADC. Signed-off-by: Andreas Färber --- v3 -> v4: * Renamed /memory node to resolve dtc warning v2 -> v3: * Squashed GMAC, eMMC, IR, TSADC (Heiko) * Fixed IR pinctrl pull setting (Julien) * Changed TSADC polarity (rebooted immediately due to fixed otp-out pin) v1 -> v2: * Dropped rk3368-geekbox.dtsi. rk3368-geekbox-landingship.dts can #include "rk3368-geekbox.dts" just fine, when leaving out /dts-v1/;. * Revisited always-on / boot-on for PMIC regulator nodes. (Heiko) * Switched pmic-sleep from RK_FUNC_GPIO to RK_FUNC_2.
