 12gpiogap=[n], hscfgcmd
 13	These commands are used to configure the host sleep parameters::
 14	bit 8:0  -- Gap
 15	bit 16:8 -- GPIO
 16
 17	where GPIO is the pin number of GPIO used to wake up the host.
 18	It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface
 19	wakeup will be used instead).
 20
 21	where Gap is the gap in milli seconds between wakeup signal and
 22	wakeup event, or 0xff for special host sleep setting.
 23
 24	Usage::
 25
 26		# Use SDIO interface to wake up the host and set GAP to 0x80:
 27		echo 0xff80 > /debug/btmrvl/config/gpiogap
 28		echo 1 > /debug/btmrvl/config/hscfgcmd
 29
 30		# Use GPIO pin #3 to wake up the host and set GAP to 0xff:
 31		echo 0x03ff >  /debug/btmrvl/config/gpiogap
 32		echo 1 > /debug/btmrvl/config/hscfgcmd
 33
 34psmode=[n], pscmd
 35	These commands are used to enable/disable auto sleep mode
 36
 37	where the option is::
 38
 39			1 	-- Enable auto sleep mode
 40			0 	-- Disable auto sleep mode
 41
 42	Usage::
 43
 44		# Enable auto sleep mode
 45		echo 1 > /debug/btmrvl/config/psmode
 46		echo 1 > /debug/btmrvl/config/pscmd
 47
 48		# Disable auto sleep mode
 49		echo 0 > /debug/btmrvl/config/psmode
 50		echo 1 > /debug/btmrvl/config/pscmd
 51
 52
 53hsmode=[n], hscmd
 54	These commands are used to enable host sleep or wake up firmware
 55
 56	where the option is::
 57
 58			1	-- Enable host sleep
 59			0	-- Wake up firmware
 60
 61	Usage::
 62
 63		# Enable host sleep
 64		echo 1 > /debug/btmrvl/config/hsmode
 65		echo 1 > /debug/btmrvl/config/hscmd
 66
 67		# Wake up firmware
 68		echo 0 > /debug/btmrvl/config/hsmode
 69		echo 1 > /debug/btmrvl/config/hscmd

 72Get driver status
 73=================
 74
 75Path:	/debug/btmrvl/status/
 76
 77Usage::
 78
 79	cat /debug/btmrvl/status/<args>
 80
 81where the args are:
 82
 83curpsmode
 84	This command displays current auto sleep status.
 85
 86psstate
 87	This command display the power save state.
 88
 89hsstate
 90	This command display the host sleep state.
 91
 92txdnldrdy
 93	This command displays the value of Tx download ready flag.
 94
 95Issuing a raw hci command
 96=========================
 97
 98Use hcitool to issue raw hci command, refer to hcitool manual
 99
100Usage::
101
102	Hcitool cmd <ogf> <ocf> [Parameters]
103
104Interface Control Command::
105
106	hcitool cmd 0x3f 0x5b 0xf5 0x01 0x00    --Enable All interface
107	hcitool cmd 0x3f 0x5b 0xf5 0x01 0x01    --Enable Wlan interface
108	hcitool cmd 0x3f 0x5b 0xf5 0x01 0x02    --Enable BT interface
109	hcitool cmd 0x3f 0x5b 0xf5 0x00 0x00    --Disable All interface
110	hcitool cmd 0x3f 0x5b 0xf5 0x00 0x01    --Disable Wlan interface
111	hcitool cmd 0x3f 0x5b 0xf5 0x00 0x02    --Disable BT interface
