Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

clk: samsung: exynos990: Fix PERIC0/1 USI clock types

2026-05-30T16:50:36+00:00

Use nMUX() for USI and UART user muxes to allow reparenting between OSC and CMU IP output when changing rates, and use DIV_F() with CLK_SET_RATE_PARENT on their dividers and gates so rate requests propagate upward. Consolidate identical USI parent arrays into shared mout_peric0_nonbususer_p and mout_peric1_nonbususer_p.

firmware: samsung: acpm: remove compile-testing stubs

2026-05-29T14:05:31+00:00

Sashiko reported an inconsistent use of NULL vs ERR_PTR() returns in the stub helpers in xynos-acpm-protocol.h. Since this only happens on dead code for COMPILE_TEST=y, this is not really a bug though. Having stub functions that return NULL is a common way to define optional interfaces, where callers still work when the feature is disabled, though this clearly does not work for acpm because some callers have a NULL pointer dereference when compile testing. Since CONFIG_EXYNOS_ACPM_PROTOCOL already supports compile-testing itself, and all (both) drivers using it clearly require the support, so this just simplifies the option space without losing any build coverage. Remove the stub functions entirely and adjust the one Kconfig dependency to require EXYNOS_ACPM_PROTOCOL unconditionally.

firmware: samsung: acpm: Make acpm_ops const and access via pointer

2026-05-29T14:02:21+00:00

Replace the embedded `struct acpm_ops` inside `struct acpm_handle` with a pointer to a `const struct acpm_ops`. Previously, the operations structure was embedded directly within the handle and populated dynamically at runtime via `acpm_setup_ops()`. This resulted in mutable function pointers and unnecessary per-instance memory overhead. By defining `exynos_acpm_driver_ops` statically as a `const` structure, the function pointers are now safely housed in the read-only `.rodata` section. This improves security by preventing function pointer overwrites, saves memory, and slightly reduces initialization overhead in `acpm_probe()`. Consequently, update all consumer drivers (clk, mfd) to access the operations via the new pointer indirection (`->ops->`). Finally, fix the previously empty kernel-doc description for the ops member to reflect its new pointer nature.

firmware: samsung: acpm: Drop redundant _ops suffix in acpm_ops members

2026-05-29T14:02:21+00:00

Rename the `dvfs_ops` and `pmic_ops` members of `struct acpm_ops` to `dvfs` and `pmic` respectively. Since these members are housed within the `acpm_ops` structure and utilize the `acpm_*_ops` types, the `_ops` suffix on the variable names creates unnecessary redundancy (e.g., `handle.ops.dvfs_ops`). This cleanup removes the stuttering, leading to cleaner consumer code.
