2			README for btmrvl driver
3	=======================================================================
4	
5	
6	All commands are used via debugfs interface.
7	
8	=====================
9	Set/get driver configurations:
10	
11	Path:	/debug/btmrvl/config/
12	
13	gpiogap=[n]
14	hscfgcmd
15		These commands are used to configure the host sleep parameters.
16		bit 8:0  -- Gap
17		bit 16:8 -- GPIO
18	
19		where GPIO is the pin number of GPIO used to wake up the host.
20		It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface
21		wakeup will be used instead).
22	
23		where Gap is the gap in milli seconds between wakeup signal and
24		wakeup event, or 0xff for special host sleep setting.
25	
26		Usage:
27			# Use SDIO interface to wake up the host and set GAP to 0x80:
28			echo 0xff80 > /debug/btmrvl/config/gpiogap
29			echo 1 > /debug/btmrvl/config/hscfgcmd
30	
31			# Use GPIO pin #3 to wake up the host and set GAP to 0xff:
32			echo 0x03ff >  /debug/btmrvl/config/gpiogap
33			echo 1 > /debug/btmrvl/config/hscfgcmd
34	
35	psmode=[n]
36	pscmd
37		These commands are used to enable/disable auto sleep mode
38	
39		where the option is:
40				1 	-- Enable auto sleep mode
41				0 	-- Disable auto sleep mode
42	
43		Usage:
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	
53	hsmode=[n]
54	hscmd
55		These commands are used to enable host sleep or wake up firmware
56	
57		where the option is:
58				1	-- Enable host sleep
59				0	-- Wake up firmware
60	
61		Usage:
62			# Enable host sleep
63			echo 1 > /debug/btmrvl/config/hsmode
64			echo 1 > /debug/btmrvl/config/hscmd
65	
66			# Wake up firmware
67			echo 0 > /debug/btmrvl/config/hsmode
68			echo 1 > /debug/btmrvl/config/hscmd
69	
70	
71	======================
72	Get driver status:
73	
74	Path:	/debug/btmrvl/status/
75	
76	Usage:
77		cat /debug/btmrvl/status/<args>
78	
79	where the args are:
80	
81	curpsmode
82		This command displays current auto sleep status.
83	
84	psstate
85		This command display the power save state.
86	
87	hsstate
88		This command display the host sleep state.
89	
90	txdnldrdy
91		This command displays the value of Tx download ready flag.
92	
93	
94	=====================
95	
96	Use hcitool to issue raw hci command, refer to hcitool manual
97	
98		Usage: Hcitool cmd <ogf> <ocf> [Parameters]
99	
100		Interface Control Command
101		hcitool cmd 0x3f 0x5b 0xf5 0x01 0x00    --Enable All interface
102		hcitool cmd 0x3f 0x5b 0xf5 0x01 0x01    --Enable Wlan interface
103		hcitool cmd 0x3f 0x5b 0xf5 0x01 0x02    --Enable BT interface
104		hcitool cmd 0x3f 0x5b 0xf5 0x00 0x00    --Disable All interface
105		hcitool cmd 0x3f 0x5b 0xf5 0x00 0x01    --Disable Wlan interface
106		hcitool cmd 0x3f 0x5b 0xf5 0x00 0x02    --Disable BT interface
