-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.

-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.
