This driver was orginally from linux-loongson-community. I Just do some clean up and port to mainline kernel tree.

Please don't depend on INPUT, it's going to drive users crazy because mortals less familiar with the configuration process for this platform almost certainly won't know that INPUT needs to be enabled so LEMOTE_YEELOONG2F can be selected. This will require further changes because you can't force INPUT_SPARSEKMAP and INPUT_EVDEV on if you don't know INPUT is selected. It also looks as if your Kconfig changes won't work properly if INPUT_MISC has not been selected manually. > endif # MIPS_PLATFORM_DEVICES > diff --git a/drivers/platform/mips/Makefile b/drivers/platform/mips/Makefile > index 8dfd03924c37..b3172b081a2f 100644 > --- a/drivers/platform/mips/Makefile > +++ b/drivers/platform/mips/Makefile > @@ -1 +1,4 @@ > obj-$(CONFIG_CPU_HWMON) += cpu_hwmon.o > + > +obj-$(CONFIG_LEMOTE_YEELOONG2F) += yeeloong_laptop.o > +CFLAGS_yeeloong_laptop.o = -I$(srctree)/arch/mips/loongson/lemote-2f > diff --git a/drivers/platform/mips/yeeloong_laptop.c b/drivers/platform/mips/yeeloong_laptop.c > new file mode 100644 > index 000000000000..280f2044858b > --- /dev/null > +++ b/drivers/platform/mips/yeeloong_laptop.c > @@ -0,0 +1,1143 @@ > +/* > + * Driver for YeeLoong laptop extras > + * > + * Copyright (C) 2017 Jiaxun Yang. > + * Author: Jiaxun Yang <jiaxun.yang@flygoat.com> > + * > + * Copyright (C) 2009 Lemote Inc. > + * Author: Wu Zhangjin <wuzhangjin@gmail.com>, Liu Junliang <liujl@lemote.com> > + * > + * Fixes: Petr Pisar <petr.pisar@atlas.cz>, 2012, 2013, 2014, 2015. > + * > + * This program is free software; you can redistribute it and/or modify > + * it under the terms of the GNU General Public License version 2 as > + * published by the Free Software Foundation. > + */ > + > +#include <linux/err.h> > +#include <linux/platform_device.h> > +#include <linux/backlight.h> /* for backlight subdriver */ > +#include <linux/fb.h> > +#include <linux/hwmon.h> /* for hwmon subdriver */ > +#include <linux/hwmon-sysfs.h> > +#include <linux/kernel.h> /* for clamp_val() */ > +#include <linux/input.h> /* for hotkey subdriver */ > +#include <linux/input/sparse-keymap.h> > +#include <linux/interrupt.h> > +#include <linux/delay.h> > +#include <linux/power_supply.h> /* for AC & Battery subdriver */ > +#include <linux/module.h> /* For MODULE_DEVICE_TABLE() */ > + > +#include <asm/bootinfo.h> > + > +#include <cs5536/cs5536.h> > + > +#include <loongson.h> /* for loongson_cmdline */ > +#include <ec_kb3310b.h> > + > +/* common function */ > +#define EC_VER_LEN 64 > + > +static int ec_version_before(char *version) > +{ > + char *p, ec_ver[EC_VER_LEN]; > + > + p = strstr(loongson_cmdline, "EC_VER="); > + if (!p) > + memset(ec_ver, 0, EC_VER_LEN); > + else { > + strncpy(ec_ver, p, EC_VER_LEN); > + p = strstr(ec_ver, " "); > + if (p) > + *p = '\0'; > + } > + > + return (strncasecmp(ec_ver, version, 64) < 0); > +} > + > +/* backlight subdriver */ > +#define MAX_BRIGHTNESS 8 > + > +static int yeeloong_set_brightness(struct backlight_device *bd) > +{ > + unsigned int level, current_level; > + static unsigned int old_level; > + > + level = (bd->props.fb_blank == FB_BLANK_UNBLANK && > + bd->props.power == FB_BLANK_UNBLANK) ?

GCC expects gas to be in reorder mode at the end of every bit of inline assembler, so above code is at the mercy of GCC. Not sure what the intent was here, was it to avoid GCC from reordering the outl() calls? These are already marked volatlile and should not be reordered by GCC. .set (no)reorder on the other hand is a directive to GAS and GCC won't be influenced at all by it.

This yeeloong_laptop module enables access to sensors, battery, video camera switch, external video connector event, and some additional buttons. This driver was orginally from linux-loongson-community. I Just do some clean up and port to mainline kernel tree.
