Subject: [PATCH v2 1/6] ARM: OMAP4: PRM: Remove hardcoding of PRM_IO_PMCTRL_OFFSET register
Date: Wed, 8 Jul 2015 11:12:23 +0530 [thread overview]
Message-ID: <1436334148-9309-2-git-send-email-j-keerthy@ti.com> (raw)
In-Reply-To: <1436334148-9309-1-git-send-email-j-keerthy@ti.com>
PRM_IO_PMCTRL_OFFSET need not be same for all SOCs hence
remove hardcoding and use the value provided by the omap_prcm_irq_setup
structure.
