      OMAP2+: clockdomain: add flag that will block autodeps from being added for a clockdomain · 570b54c7
      Paul Walmsley authored 
      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.

      OMAP2+: hwmod: add API to handle autoidle mode · 9599217a
      Kishon Vijay Abraham I authored 
      Create a new API that forms a wrapper to _set_module_autoidle()
to modify the AUTOIDLE bit.

This API is intended to be used by drivers that requires direct
manipulation of the AUTOIDLE bits in SYSCONFIG register.
McBSP driver requires autoidle bit to be enabled/disabled while
using sidetone feature.

[paul@pwsan.com: restrict the hwmod states that the autoidle bit can be changed
 in; changed function name; dropped "int" from "unsigned int long"]

      OMAP2+: hwmod: allow board files to prevent devices from being reset upon init · 43b01643
      Paul Walmsley authored 
      Some boards can't tolerate IP blocks being reset when they are initialized.
Michael Büsch cites a case with the Nokia N810:

    http://www.spinics.net/lists/linux-omap/msg47277.html

To allow such boards to continue working normally, allow board file
maintainers to mark IP blocks to prevent them from being reset upon
init.  This is done via a hwmod function, omap_hwmod_no_setup_reset().
