From de1d08b229746fc650c56ce7ddff34b1c8e778df Mon Sep 17 00:00:00 2001 From: Ludovic Barre Date: Tue, 17 Jul 2018 11:56:26 +0200 Subject: dt-bindings: pinctrl: add syscfg mask parameter This patch adds mask parameter to define IRQ mux field. This field could vary depend of IRQ mux selection register. This parameter is needed if the mask is different of 0xf.
