Hi Bart,
These changes include add "inten_offset" and use use "u32" replaced
"unsigned int", which type change was due to v3 has following code,
but, in v5 gpio patch, no following code, so no need type change.
104 + if (device_property_read_u32(dev,
"loongson,gpio-conf-offset", (u32 *)&d->conf_offset)
105 + || device_property_read_u32(dev,
"loongson,gpio-in-offset", (u32 *)&d->in_offset)
106 + || device_property_read_u32(dev,
"loongson,gpio-out-offset", (u32 *)&d->out_offset)
107 + || device_property_read_u32(dev,
"loongson,gpio-ctrl-mode", (u32 *)&d->mode))
I will add following change in v6.

Change the commit log to the following:
This patch was to add loongson 2k0500, 2k2000 and 3a5000 gpio chip
driver support and define inten_offset attribute to enable gpio chip
interrupt.
