powerpc/pasemi: mark pas_shutdown() static

2023-11-21T01:06:50+00:00

Allmodconfig builds show a warning about one function that is accidentally
marked global:

arch/powerpc/platforms/pasemi/setup.c:67:6: error: no previous prototype for 'pas_shutdown' [-Werror=missing-prototypes]

powerpc: Explicitly include correct DT includes

2023-08-02T12:22:19+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.

powerpc: Make generic_calibrate_decr() the default

2023-03-15T21:56:48+00:00

ppc_md.calibrate_decr() is a mandatory item. Its nullity is never
checked so it must be non null on all platforms.

Most platforms define generic_calibrate_decr() as their
ppc_md.calibrate_decr(). Have time_init() call
generic_calibrate_decr() when ppc_md.calibrate_decr() is NULL,
and remove default assignment from all machines.

powerpc: Add missing headers

2022-05-08T12:15:40+00:00

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h,
asm/pci.h etc...

Include the needed headers, and remove asm/prom.h when it was
needed exclusively for pulling necessary headers.

powerpc/pasemi: Add __init attribute to eligible functions

2021-12-23T11:33:14+00:00

Some functions defined in 'arch/powerpc/platforms/pasemi' are deserving
of an `__init` macro attribute. These functions are only called by other
initialization functions and therefore should inherit the attribute.
Also, change function declarations in header files to include `__init`.

powerpc/dma: use the generic direct mapping bypass

2019-02-18T11:41:04+00:00

Now that we've switched all the powerpc nommu and swiotlb methods to
use the generic dma_direct_* calls we can remove these ops vectors
entirely and rely on the common direct mapping bypass that avoids
indirect function calls entirely.  This also allows to remove a whole
lot of boilerplate code related to setting up these operations.
