The kernel.h is not used here directly, replace it with proper
set of headers.

interconnect: Explicitly include correct DT includes

2023-07-16T15:27:27+00:00

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.

interconnect: imx: fix registration race

2023-03-07T20:19:05+00:00

The current interconnect provider registration interface is inherently
racy as nodes are not added until the after adding the provider. This
can specifically cause racing DT lookups to fail.

Switch to using the new API where the provider is not registered until
after it has been fully initialised.

interconnect: imx: Make imx_icc_unregister() return void

2022-08-18T04:20:41+00:00

The function imx_icc_unregister() returns zero unconditionally. Make it
return void.

This is a preparation for making platform remove callbacks return void.

interconnect: imx: Ignore return value of icc_provider_del() in .remove()

2022-08-16T13:37:36+00:00

icc_provider_del() already emits an error message on failure. In this
case letting .remove() return the corresponding error code results in
another error message and the device is removed anyhow. (See
platform_remove().)

So ignore the return value of icc_provider_del() and return 0
unconditionally.

This is a preparation for making platform remove callbacks return void.

When set QoS for a icc path, only set dst icc node is not enough,
also need to set src icc node.
