be always-on as long as the APSS is online and only has to run
at 19.2 MHz. Define it to be as such in the ACTIVE domain.

Some SoCs use that clock for bus scaling, while others just need it for
reaching the hardware. This commit will hurt neither.

Some clocks, at least PCNoC (a.k.a CNoC_PERIPH) need to be always on,

Introduce a new macro to preset non-INT_MAX rates and clk flags to make

clk: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The interconnect bus clocks are now handled within the ICC framework.
They still however need to get a kickstart *before* we call
clk_smd_rpm_enable_scaling(), or RPM will assume that they should all
be running at 0 kHz and the system will inevitably die.

Separate them out to ensure such a kickstart can still take place.

soc: qcom: smd-rpm: Move icc_smd_rpm registration to clk-smd-rpm

icc_smd_rpm will do bus clock votes itself rather than taking the
unnecessary detour through the clock subsystem. However, it can only
do that after the clocks have been handed off and scaling has been
enabled in the RPM in clk-smd-rpm.

Move the icc_smd_rpm registration from smd-rpm.c to clk-smd-rpm.c
to avoid any possible races. icc_smd_rpm gets the driver data from
the smd-rpm device, so still register the platform device on the
smd-rpm parent device.

clk: qcom: smd-rpm: conditionally enable scaling before doing handover

On older platforms like msm8226, msm8974 and msm8916 the driver in the
downstream kernel enables scaling first before doing the handover of the
clocks.

While this normally doesn't seem to cause noticeable problems, on
apq8026-asus-sparrow this causes the device to immediately reboot,
perhaps due to older rpm firmware that becomes unhappy.

On newer platforms the order has swapped and enabling scaling is done
after the handover, so let's introduce this behavior only conditionally
for msm8226 and msm8974 for now.
