Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using git grep -l '\

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

clk: mmp: Switch to use struct u32_fract instead of custom one

2024-11-14T22:32:50+00:00

The struct mmp_clk_factor_tbl repeats the generic struct u32_fract. Kill the custom one and use the generic one instead.

clk: mmp2: Move number of clocks to driver source

2023-08-22T21:13:45+00:00

The number of clocks should not be in the dt binding as it is not used by the respective device tree and thus needlessly bloats the ABI. Move this number of clocks into the driver source.

Now that clk_register_mux_table takes a const u32 *, we can declare the mux tables as const u32[]. Signed-off-by: Jonathan Neuschäfer Link: https://lore.kernel.org/r/20220205103613.1216218-6-j.neuschaefer@gmx.net Signed-off-by: Stephen Boyd

clk: mmp2: Fix the display clock divider base

The LCD clock dividers are apparently based on one.

clk: mmp2: Add support for power islands

2020-05-28T00:55:12+00:00

Apart from the clocks and resets, the PMU hardware also controls power to peripherals that are on separate power islands. On MMP2, that's the GC860 GPU and the SSPA audio interface, while on MMP3 also the camera interface is on a separate island, along with the pair of GC2000 and GC300 GPUs and the SSPA.
