peci: controller: peci-aspeed: convert from round_rate() to determine_rate()

2025-11-06T13:51:37+00:00

The round_rate() clk ops is deprecated, so migrate this driver from round_rate() to determine_rate() using the Coccinelle semantic patch appended to the "under-the-cut" portion of the patch.

module: Convert symbol namespace to string literal

2024-12-02T19:34:44+00:00

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

peci: npcm: Constify struct peci_controller_ops

2024-10-25T08:58:07+00:00

'struct peci_controller_ops' is not modified in this driver. Constifying this structure moves some data to a read-only section, so increase overall security, especially when the structure holds some function pointers.

move asm/unaligned.h to linux/unaligned.h

As with most ops structs, we never modify it at runtime, and keeping function pointers in read-only memory is generally a good thing security-wise.
