From a26a029893096204f08a3ff5e262f99e1a75e273 Mon Sep 17 00:00:00 2001 From: Peter De Schrijver Date: Wed, 3 Apr 2013 17:40:42 +0300 Subject: clk: tegra: Add flags to tegra_clk_periph() We will need some tegra peripheral clocks with the CLK_IGNORE_UNUSED flag, most notably mselect, which is a bridge between AXI and most peripherals.
