3 =======================================================================
6 All commands are used via debugfs interface.
9 Set/get driver configurations:
11 Path: /debug/btmrvl/config/
15 These commands are used to configure the host sleep parameters.
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).
23 where Gap is the gap in milli seconds between wakeup signal and
24 wakeup event, or 0xff for special host sleep setting.
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
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
37 These commands are used to enable/disable auto sleep mode
40 1 -- Enable auto sleep mode
41 0 -- Disable auto sleep mode
44 # Enable auto sleep mode
45 echo 1 > /debug/btmrvl/config/psmode
46 echo 1 > /debug/btmrvl/config/pscmd
48 # Disable auto sleep mode
49 echo 0 > /debug/btmrvl/config/psmode
50 echo 1 > /debug/btmrvl/config/pscmd
55 These commands are used to enable host sleep or wake up firmware
58 1 -- Enable host sleep
63 echo 1 > /debug/btmrvl/config/hsmode
64 echo 1 > /debug/btmrvl/config/hscmd
67 echo 0 > /debug/btmrvl/config/hsmode
68 echo 1 > /debug/btmrvl/config/hscmd
71 ======================
74 Path: /debug/btmrvl/status/
77 cat /debug/btmrvl/status/<args>
82 This command displays current auto sleep status.
85 This command display the power save state.
88 This command display the host sleep state.
91 This command displays the value of Tx download ready flag.
