Commit 2f7ae8ab6aa73 ("clk: microchip: mpfs-ccc: fix out of bounds access during output registration") fixed the out of bounds access, but it did so by packing sparse indices into a linear space. When peripheral drivers request clocks, they obviously don't care for this compression and use the sparse indices, and therefore try to request the wrong clocks or clocks that don't exist. The most straightforward fix here seems to stop being clever with the packing and just overallocate the array.

clk: microchip: rename clk-core to clk-pic32

2026-05-05T14:30:03+00:00

clk-core is a confusingly generic name, since it is only used by a single platform and it uses very similar naming to the "soft" IP cores for use in FPGA fabric (CoreClock or similar is what that would be called, although nothing like that exists right now) that the FPGA business unit produces. Rename it to clk-pic32, matching the prefix used by most functions in the driver. As far as I can tell, impact on whatever users may (or may not...) exist for the platform is minimal as it's built-in only and the functions are called directly from clk-pic32mzda.c Reviewed-by: Brian Masney Signed-off-by: Conor Dooley

clk: microchip: mpfs-ccc: fix out of bounds access during output registration

2026-03-02T17:12:45+00:00

UBSAN reported an out of bounds access during registration of the last two outputs. This out of bounds access occurs because space is only allocated in the hws array for two PLLs and the four output dividers that each has, but the defined IDs contain two DLLS and their two outputs each, which are not supported by the driver. The ID order is PLLs -> DLLs -> PLL outputs -> DLL outputs. Decrement the PLL output IDs by two while adding them to the array to avoid the problem.

clk: microchip: core: allow driver to be compiled with COMPILE_TEST

2026-01-30T14:29:08+00:00

This driver currently only supports builds against a PIC32 target. To avoid future breakage in the future, let's update the Kconfig and the driver so that it can be built with CONFIG_COMPILE_TEST enabled. Note that with the existing asm calls is not how I'd want to do this today if this was a new driver, however I don't have access to this hardware. To avoid any breakage, let's keep the existing behavior. Signed-off-by: Brian Masney Signed-off-by: Thomas Bogendoerfer

clk: microchip: core: update include to use pic32.h from platform_data

2026-01-30T14:29:08+00:00

Use the linux/platform_data/pic32.h include instead of asm/mach-pic32/pic32.h so that the asm variant can be dropped. This is in preparation for allowing some drivers to be compiled on other architectures with COMPILE_TEST enabled.
