X-Git-Tag: v2.6.39~3^2~1 X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=3e9957b4866f3767f19bf0e543b322ad7906c564;p=cascardo%2Flinux.git MIPS: AR7: Fix GPIO register size for Titan variant. The 'size' variable contains the correct register size for both AR7 and Titan, but we never used it to ioremap the correct register size. This problem only shows up on Titan. [ralf@linux-mips.org: Fixed the fix. The original patch as in patchwork recognizes the problem correctly then fails to fix it ...] Reported-by: Alexander Clouter Signed-off-by: Florian Fainelli Patchwork: https://patchwork.linux-mips.org/patch/2380/ Signed-off-by: Ralf Baechle --- diff --git a/arch/mips/ar7/gpio.c b/arch/mips/ar7/gpio.c index 425dfa5d6e12..bb571bcdb8f2 100644 --- a/arch/mips/ar7/gpio.c +++ b/arch/mips/ar7/gpio.c @@ -325,9 +325,7 @@ int __init ar7_gpio_init(void) size = 0x1f; } - gpch->regs = ioremap_nocache(AR7_REGS_GPIO, - AR7_REGS_GPIO + 0x10); - + gpch->regs = ioremap_nocache(AR7_REGS_GPIO, size); if (!gpch->regs) { printk(KERN_ERR "%s: failed to ioremap regs\n", gpch->chip.label);
