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

2024-10-02T21:23:23+00:00

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

peci: aspeed: Clear clock_divider value before setting it

2024-06-17T13:18:29+00:00

PECI clock divider is programmed on 10:8 bits of PECI Control register.
Before setting a new value, clear bits read from hardware.

peci: Constify struct peci_controller_ops

2023-08-04T14:21:30+00:00

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()

2022-08-15T18:31:34+00:00

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

2022-02-09T07:04:43+00:00

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.
