From 1d18a3f0f0809f6c71f1f6e9e268ee904ce0b588 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Tue, 3 May 2016 00:17:32 +0530 Subject: [PATCH] pinctrl: tegra: avoid parked_reg and parked_bank NVIDIA's Tegra210 support the park bit to make pinmux configuration enable/disable. If parked bit is 1 then configuration does not apply and if it is 0 then pinmux configuration applies. This is to support to avoid any glitch in pinmux configurations. The parked bit is part of mux register and mux bank and hence it is not required to have member for the parked_reg and parked bank very similar to other bit field of the same register. Remove the need of the parked register and parked bank and get whether parked function supported or not by parked_bit. This is to make the parked bit handling same as other fields of mux registers.
