2017-10-25gpio: loongson1: fix bgpio usageLinus Walleij
When no flags are given, the native endianness is used to access the MMIO registers, and the pin2mask() call can simply be converted to a BIT() call, as per the default pin2mask() implementation in gpio-mmio.c.

2016-09-15gpio: loongson1: fix implicit assumption module.h is presentPaul Gortmaker
The Kconfig for this file is: drivers/gpio/Kconfig:config GPIO_LOONGSON1 drivers/gpio/Kconfig: tristate "Loongson1 GPIO support" ...but however it does not include module.h -- it in turn gets it from another header (gpio/driver.h) and we'd like to replace that with a forward delcaration of "struct module;" but if we do, this file will fail to compile. So we fix this first to avoid putting build failures into the bisect commit history.
