powerpc/pasemi: Use strscpy instead of strlcpy

2022-09-06T01:03:04+00:00

find_i2c_driver() contained the last usage of strlcpy() in arch/powerpc.
The return value was used to check if strlen(src) >= n, for which
strscpy() returns -E2BIG.

powerpc: Add missing headers

2022-05-08T12:15:40+00:00

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h,
asm/pci.h etc...

Include the needed headers, and remove asm/prom.h when it was
needed exclusively for pulling necessary headers.

powerpc/pasemi: Use pr_err/pr_warn... for kernel messages

2018-08-07T14:32:31+00:00

Pasemi code still uses printk(KERN_ERR/KERN_WARN ... change these to
pr_err(, pr_warn(... to match other powerpc arch code.

No functional changes.

powerpc: Remove all usages of NO_IRQ

2016-09-20T10:57:12+00:00

NO_IRQ has been == 0 on powerpc for just over ten years (since commit
0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change
platforms to use it")). It's also 0 on most other arches.

Although it's fairly harmless, every now and then it causes confusion
when a driver is built on powerpc and another arch which doesn't define
NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least
some of which are to work around that problem.

So we'd like to remove it. This is fairly trivial in the arch code, we
just convert:

    if (irq == NO_IRQ)	to	if (!irq)
    if (irq != NO_IRQ)	to	if (irq)
    irq = NO_IRQ;	to	irq = 0;
    return NO_IRQ;	to	return 0;

And a few other odd cases as well.

At least for now we keep the #define NO_IRQ, because there is driver
code that uses NO_IRQ and the fixes to remove those will go via other
trees.

Note we also change some occurrences in PPC sound drivers, drivers/ps3,
and drivers/macintosh.

[POWERPC] pasemi: Register i2c devices at boot

2008-02-21T10:08:35+00:00

Setup i2c_board_info based on device tree contents.  This has to be
a device_initcall since we need PCI to be probed by the time we
run it, but before the actual driver is initialized.
