powerpc: Remove cpm_dp...() macros

2023-10-20T12:18:07Z

Since commit d3c511ac1d72 ("powerpc/cpm: Remove !CONFIG_PPC_CPM_NEW_BINDING code") cpm_dp...() macros have no added value anymore. Last user of those macros were fixed by commit 5e6cb39a256d ("net: fs_enet: Use cpm_muram_xxx() functions instead of cpm_dpxxx() macros") Remove them.

soc/fsl: cpm: tsa: Convert to platform remove callback returning void

2023-10-14T21:26:57Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

soc: fsl: Explicitly include correct DT includes

2023-08-12T08:31:02Z

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.

soc: fsl: qe: Replace all non-returning strlcpy with strscpy

2023-07-17T23:05:20Z

strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.
