2024-03-03powerpc/machdep: Define 'compatibles' property in ppc_md and use itChristophe Leroy1-3/+1
Most probe functions that do not use the 'compatible' string do nothing else than checking whether the machine is compatible with one of the strings in a NULL terminated table of strings. Define that table of strings in ppc_md structure and check it directly from probe_machine() instead of using ppc_md.probe() for that. Keep checking in ppc_md.probe() only for more complex probing. All .compatible could be replaced with a single element NULL terminated list but that's not worth the churn. Can be do incrementaly in follow-up patches.

2023-08-02powerpc: Explicitly include correct DT includesRob Herring1-1/+1
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.

2023-03-16powerpc: Make generic_calibrate_decr() the defaultChristophe Leroy1-1/+0
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.

It is now called right after platform probe, so the probe function can just do the job. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
2016-07-21powerpc: Move 32-bit probe() machine to later in the boot processBenjamin Herrenschmidt1-1/+1
This converts all the 32-bit platforms to use the expanded device-tree which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel didn't rely on platform initializations to setup the MMU since it sets it up entirely before probe_machine() so the move has comparatively less consequences though it's a bigger patch.

2013-05-21powerpc/mpc512x: move common code to shared.c fileGerhard Sittig1-2/+2
- implement all of the init, init early, and setup arch routines in the shared source file for the MPC512x PowerPC platform, and make all MPC512x based boards (ADS, PDM, generic) use those common routines - remove declarations from header files for routines which aren't referenced from external callers any longer this modification concentrates knowledge about the optional FSL DIU support in one spot within the shared code, and makes all boards benefit transparently from future improvements in the shared platform code the change does not modify any behaviour but preserves all code paths Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de>

Add dts file for ac14xx board and its board compatible string to the generic mpc512x board match list. Also add phandle to the dma DT node since there is a change (for MPC5121 SDHC DMA support) merged via linux-mmc tree with reference to the dma controller node in the sdhc node.
