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: Use of_property_present() for testing DT property presence

2023-03-30T12:36:35+00:00

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

powerpc/mpic_msgr: fix cast removes address space of expression warnings

2022-11-24T12:31:49+00:00

When build Linux kernel, encounter the following warnings: ./arch/powerpc/sysdev/mpic_msgr.c:230:38: warning: cast removes address space '__iomem' of expression ./arch/powerpc/sysdev/mpic_msgr.c:230:27: warning: incorrect type in assignment (different address spaces) The data type of msgr->mer and msgr->base are 'u32 __iomem *', but converted to 'u32 *' and 'u8 *' directly and cause above warnings, now instead of using a type cast, change the size of the pointer offset to fix these warnings.

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: sysdev: add missing iounmap() on error in mpic_msgr_probe()

2020-11-19T03:50:14+00:00

I noticed that iounmap() of msgr_block_addr before return from mpic_msgr_probe() in the error handling case is missing. So use devm_ioremap() instead of just ioremap() when remapping the message register block, so the mapping will be automatically released on probe failure.

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.
