    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
