If I rebase this patch on top clk-next, I am getting conflicts when I merge that with linux-next. Let me know how you want to handle this. I am attaching the rebased patches for your reference. If you want, I will send them again through git-send-email. From 5f3843da7bc71d126c0cce7a8e88aab1850c4b9c Mon Sep 17 00:00:00 2001 From: Tushar Behera Date: Wed, 30 Oct 2013 15:56:27 +0530 Subject: [PATCH 2/4] clk: clk-s2mps11: Add support for clocks in S5M8767 MFD Since clock operation within S2MPS11 and S5M8767 are similar, we can support both the devices within a single driver.
