570b54c7fa 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.

4da71ae607 OMAP: clockdomain: Arch specific funcs for clkdm_clk_enable/disable
Define the following architecture specific funtions for omap2/3/4
.clkdm_clk_enable
.clkdm_clk_disable

Convert the platform-independent framework to call these functions.
Also rename the api's by removing the omap2_ preamble.
Hence call omap2_clkdm_k_enable as clkdm_clk_enable and
omap2_clkdm_clk_disable as clkdm_clk_disable.a

Remove unused functions (_enable/_disable_hwsup) and unsed
headers from clockdomain.c file.

5cd1937b6d OMAP: clockdomain: Arch specific funcs for hwsup control of clkdm
Define the following architecture specific funtions for omap2/3/4

Also rename the api's by removing the omap2_ preamble.
Hence call omap2_clkdm_allow_idle as clkdm_allow_idle and
omap2_clkdm_deny_idle as clkdm_deny_idle.

Make the _clkdm_add_autodeps and _clkdm_del_autodeps as non-static
so they can be accessed from OMAP2/3 platform specific code.

32d4034eea OMAP: clockdomain: Infrastructure to put arch specific code
Put infrastructure in place, so arch specific func pointers
can be hooked up to the platform-independent part of the
framework.
This is in preparation of splitting the clockdomain framework into
platform-independent part (for all omaps) and platform-specific
parts.

302991379c omap2plus: clockdomain: Trivial fix for build break because of clktrctrl_mask
struct clockdomain member clktrctrl_mask is available for only for OMAP2
and OMAP3 architectures. Technially it is also used only for these archs
but this breaks the build with custom OMAP4 configuration.

72e06d0872 OMAP2+: powerdomain: move header file from plat-omap to mach-omap2
The OMAP powerdomain code and data is all OMAP2+-specific.  This seems
unlikely to change any time soon.  Move plat-omap/include/plat/powerdomain.h
to mach-omap2/powerdomain.h.  The primary point of doing this is to remove
the temptation for unrelated upper-layer code to access powerdomain code
and data directly.

As part of this process, remove the references to powerdomain data
from the GPIO "driver" and the OMAP PM no-op layer, both in plat-omap.
Change the DSPBridge code to point to the new location for the
powerdomain headers.  The DSPBridge code should not be including the
powerdomain headers; these should be removed.

DSPBridge also uses the clockdomain headers for some reason, so,
modify it also. The DSPBridge code should not be including the
