From f0caa5270bcf97c6a51c89d44747da00c0d67bb8 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Fri, 4 Apr 2014 12:14:27 +0300 Subject: [PATCH] ARM: OMAP3: PRM: invert the wkst_mask for the prm_clear_mod_irqs This makes the API the same as used with OMAP2, and makes it possible to implement a generic driver API for the functionality.
