   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

  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
