Message-ID: <cover.1335266056.git.viresh.kumar@st.com> Date: Tue, 24 Apr 2012 16:51:22 +0530 From: Viresh Kumar <viresh.kumar@...com> To: <akpm@...ux-foundation.org> Cc: <spear-devel@...t.st.com>, <viresh.linux@...il.com>, <linux-kernel@...r.kernel.org>, <linux-arm-kernel@...ts.infradead.org>, <mturquette@...aro.org>, <sshtylyov@...sta.com>, <jgarzik@...hat.com>, <linux@....linux.org.uk>, Viresh Kumar <viresh.kumar@...com> Subject: [PATCH V3 00/12] clk: Add non CONFIG_HAVE_CLK routines Many drivers are shared between architectures that may or may not have HAVE_CLK selected for them. To remove compilation errors for them we enclose clk_*() calls in these drivers within #ifdef CONFIG_HAVE_CLK, #endif. This patchset removes the need of these CONFIG_HAVE_CLK statements, by introducing dummy routines when HAVE_CLK is not selected by platforms. So, definition of these routines will always be available. These calls will return error for platforms that don't select HAVE_CLK. I hope i don't break anything now. ;) V2->V3: - Dummy routines now return NULL or 0. - All user drivers must fail if clk_get returned error other than NULL. - All user drivers don't need to validate their clk pointer before every call to clk_*() routines. - Patches dropped earlier are again taken back, as they were following similar approach to what is implemented now. V1->V2: - Removed few patches as they might break working drivers - Updated 1st patch, as it doesn't apply cleanly on latest linux-next after this got applied. commit a8a97db984bdc5e89d42e41891543d2daaf314cb Author: Mark Brown <broonie@...ena.org.uk> Date: Thu Apr 5 11:42:09 2012 +0100 ARM: 7376/1: clkdev: Implement managed clk_get() - Similarly, updated stmmac patch as there were updates for it too.
