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

2025-11-06T13:51:37Z

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

2024-12-02T19:34:44Z

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.

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

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

peci: aspeed: Clear clock_divider value before setting it

2024-06-17T13:18:29Z

PECI clock divider is programmed on 10:8 bits of PECI Control register. Before setting a new value, clear bits read from hardware. Reviewed-by: Billy Tsai Link: https://lore.kernel.org/r/20240417134849.5793-1-iwona.winiarska@intel.com Signed-off-by: Iwona Winiarska

peci: Constify struct peci_controller_ops

2023-08-04T14:21:30Z

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.

peci: aspeed: fix error check return value of platform_get_irq()

2022-08-15T18:31:34Z

platform_get_irq() return negative value on failure, so null check of priv->irq is incorrect. Fix it by comparing whether it is less than zero.

peci: Add peci-aspeed controller driver

2022-02-09T07:04:43Z

ASPEED AST24xx/AST25xx/AST26xx SoCs support the PECI electrical interface (a.k.a PECI wire) that provides a communication channel with Intel processors. This driver allows BMC to discover devices connected to it and communicate with them using PECI protocol.
