powerpc: 83xx: km83xx: Fix keymile vendor prefix

2026-03-19T15:14:45Z

[ Upstream commit 691417ffe7821721e0a28bd25ad8c0dc0d4ae4ad ] When kmeter.c was refactored into km83xx.c in 2011, the "keymile" vendor prefix was changed to upper-case "Keymile". The devicetree at arch/powerpc/boot/dts/kmeter1.dts never underwent the same change, suggesting that this was simply a mistake.

powerpc: Explicitly include correct DT includes

2023-08-02T12:22:19Z

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

2023-03-15T21:56:48Z

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/83xx: Add __init attribute to eligible functions

2021-12-23T11:33:18Z

Some functions defined in 'arch/powerpc/platforms/83xx' 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`.
