  12gpiogap=[n], hscfgcmd
  13        These commands are used to configure the host sleep parameters::
  14        bit 8:0  -- Gap
  15        bit 16:8 -- GPIO
  16
  17        where GPIO is the pin number of GPIO used to wake up the host.
  18        It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface
  19        wakeup will be used instead).
  20
  21        where Gap is the gap in milli seconds between wakeup signal and
  22        wakeup event, or 0xff for special host sleep setting.
  23
  24        Usage::
  25
  26                # Use SDIO interface to wake up the host and set GAP to 0x80:
  27                echo 0xff80 > /debug/btmrvl/config/gpiogap
  28                echo 1 > /debug/btmrvl/config/hscfgcmd
  29
  30                # Use GPIO pin #3 to wake up the host and set GAP to 0xff:
  31                echo 0x03ff >  /debug/btmrvl/config/gpiogap
  32                echo 1 > /debug/btmrvl/config/hscfgcmd
  33
  34psmode=[n], pscmd
  35        These commands are used to enable/disable auto sleep mode
  36
  37        where the option is::
  38
  39                        1       -- Enable auto sleep mode
  40                        0       -- Disable auto sleep mode
  41
  42        Usage::
  43
  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], hscmd
  54        These commands are used to enable host sleep or wake up firmware
  55
  56        where the option is::
  57
  58                        1       -- Enable host sleep
  59                        0       -- Wake up firmware
  60
  61        Usage::
  62
  63                # Enable host sleep
  64                echo 1 > /debug/btmrvl/config/hsmode
  65                echo 1 > /debug/btmrvl/config/hscmd
  66
  67                # Wake up firmware
  68                echo 0 > /debug/btmrvl/config/hsmode
  69                echo 1 > /debug/btmrvl/config/hscmd

  72Get driver status
  73=================
  74
  75Path:   /debug/btmrvl/status/
  76
  77Usage::
  78
  79        cat /debug/btmrvl/status/<args>
  80
  81where the args are:
  82
  83curpsmode
  84        This command displays current auto sleep status.
  85
  86psstate
  87        This command display the power save state.
  88
  89hsstate
  90        This command display the host sleep state.
  91
  92txdnldrdy
  93        This command displays the value of Tx download ready flag.
  94
  95Issuing a raw hci command
  96=========================
  97
  98Use hcitool to issue raw hci command, refer to hcitool manual
  99
 100Usage::
 101
 102        Hcitool cmd <ogf> <ocf> [Parameters]
 103
 104Interface Control Command::
 105
