Krzysztof Kozlowski	75589d6b11	pinctrl: loongson2: fix module autoloading ... Add MODULE_DEVICE_TABLE(), so the module could be properly autoloaded based on the alias from of_device_id table. Pin controllers are considered core components, so usually they are built-in, however these can be built and used as modules on some generic kernel.

Linus Walleij	7ebfe10ec3	pinctrl: loongson2: Fix some const correctness ... The kernel robot using sparse is complaining like this: drivers/pinctrl/pinctrl-loongson2.c:212:21: sparse: sparse: incorrect type in argument 1 (different address spaces) @@ expected void const volatile [noderef] __iomem *addr @@ got void *[noderef] __iomem reg @@ (...) I think the problem is simply that the register base is defined as void * __iomem instead of void __iomem * and this is because of the way const correctness works with pointer infix order. Fix it up. I think.

zhanghongchen	f73f88acbc	pinctrl: pinctrl-loongson2: add pinctrl driver support ... The Loongson-2 SoC has a few pins that can be used as GPIOs or take multiple other functions. Add a driver for the pinmuxing. There is currently no support for GPIO pin pull-up and pull-down.
