   2                README for btmrvl driver
   3=======================================================================
   4
   5
   6All commands are used via debugfs interface.
   7
   8=====================
   9Set/get driver configurations:
  10
  11Path:   /debug/btmrvl/config/
  12
  13gpiogap=[n]
  14hscfgcmd
  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
  35psmode=[n]
  36pscmd
  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
  53hsmode=[n]
  54hscmd
  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

  71======================
  72Get driver status:
  73
  74Path:   /debug/btmrvl/status/
  75
  76Usage:
  77        cat /debug/btmrvl/status/<args>
  78
  79where the args are:
  80
  81curpsmode
  82        This command displays current auto sleep status.
  83
  84psstate
  85        This command display the power save state.
  86
  87hsstate
  88        This command display the host sleep state.
  89
  90txdnldrdy
  91        This command displays the value of Tx download ready flag.
  92
  93
  94=====================
  95
  96Use hcitool to issue raw hci command, refer to hcitool manual
  97
  98        Usage: Hcitool cmd <ogf> <ocf> [Parameters]
  99
 100        Interface Control Command
