      omap2/3: dmtimer: Enable autoidle · 4ce1e5e1
      由 Tero Kristo 提交于 
      This saves some power. OMAP4 version should check for GPT module ID, as
autoidle is only supported on a subset of these.

      OMAP2+: clockdomain: add flag that will block autodeps from being added for a clockdomain · 570b54c7
      由 Paul Walmsley 提交于 
      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
      由 Kishon Vijay Abraham I 提交于 
      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.

      OMAP2+: hwmod: allow board files to prevent devices from being reset upon init · 43b01643
      由 Paul Walmsley 提交于 
      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().

      OMAP2+: hwmod: use status bit info for reset line · cc1226e7
      由 omar ramirez 提交于 
      On OMAP2 and OMAP3 the reset ctrl shift doesn't match the
status bit, as it does on OMAP4, when handling the reset lines.

This patch adds a new member in the reset info structure, so now it
can be added as part of hwmod data, and checked accordingly for
OMAP2 or 3; otherwise, there could be cases when the shift masks
doesn't match both of the registers, and a successful reset might
throw an error message or vice versa.
