From a0a4b4c2420e0af6171a2be1965bdd983d35953c Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Tue, 5 Dec 2017 15:46:45 +0100 Subject: [PATCH] pinctrl: axp209: add programmable ADC muxing value To prepare for patches that will add support for a new PMIC that has a different GPIO adc muxing value, add an adc_mux within axp20x_pctl structure and use it.
