From mboxrd@z Thu Jan 1 00:00:00 1970 From: rnayak@ti.com (Rajendra Nayak) Date: Thu, 14 Jun 2012 18:17:00 +0530 Subject: [PATCH 11/29] ARM: omap: hwmod: Fix up hwmod based clkdm accesses In-Reply-To: <1339678038-23082-1-git-send-email-rnayak@ti.com> References: <1339678038-23082-1-git-send-email-rnayak@ti.com> Message-ID: <1339678038-23082-12-git-send-email-rnayak@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org hwmod uses deferencing the clk pointer to acccess the clkdm. With COMMON clk hwoever this will need to be deferenced through the clk_hw_omap pointer, so do the necessary changes.
