OMAP2+: clockdomain: add flag that will block autodeps from being added for a clockdomain
Add a new clockdomain flag, CLKDM_NO_AUTODEPS, which, when marked on a clockdomain, will prevent "autodeps" from being associated with the clockdomain. ("Autodeps" are sleep dependencies and wakeup dependencies from/to processor modules that are automatically added to a clockdomain when it is in hardware-supervised idle mode. They are deprecated -- a relic from the old CDP trees -- but are still in use for OMAP3.) Also, prevent the hwmod code from adding or removing initiator dependencies for clockdomains with this flag set. This patch should allow others to test which clockdomains actually still need autodeps. Thanks to Kevin Hilman <khilman@ti.com> for noting that the original version should also modify the hwmod code.
