+Subject: ARM: OMAP4: hwmod: Don't wait for the idle status if modulemode is not supported
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux.git;a=commitdiff_plain;h=bfc141e3a515008d85e57af39c9faa4d2bbc65e0;hp=ddf536d0d7e1f0b63a681c970888730a4437414d
+
+ARM: OMAP4: hwmod: Don't wait for the idle status if modulemode is not supported
+
+If the module does not have any modulemode, the _disable_module function
+will do nothing. There is then no point waiting for a idle status change.
+
+It will remove the following warnings.
+
+[    0.331848] omap_hwmod: dmm: _wait_target_disable failed
+[    0.339935] omap_hwmod: emif_fw: _wait_target_disable failed

+[    0.489471] omap_hwmod: mailbox: _wait_target_disable failed
+[    0.505920] omap_hwmod: spinlock: _wait_target_disable failed
+
+Note: For such module, the state is managed automatically by HW according
+to clock domain transition. It is then not possible to wait for idle even
+later in the _idle function since the status will change at clock domain
+boundary.
