​

gpiogap=[n], hscfgcmd

    These commands are used to configure the host sleep parameters::

    bit 8:0  -- Gap

    bit 16:8 -- GPIO

​

    where GPIO is the pin number of GPIO used to wake up the host.

    It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface

    wakeup will be used instead).

​

    where Gap is the gap in milli seconds between wakeup signal and

    wakeup event, or 0xff for special host sleep setting.

​

    Usage::

​

        # Use SDIO interface to wake up the host and set GAP to 0x80:

        echo 0xff80 > /debug/btmrvl/config/gpiogap

        echo 1 > /debug/btmrvl/config/hscfgcmd

​

        # Use GPIO pin #3 to wake up the host and set GAP to 0xff:

        echo 0x03ff >  /debug/btmrvl/config/gpiogap

        echo 1 > /debug/btmrvl/config/hscfgcmd

​

psmode=[n], pscmd

    These commands are used to enable/disable auto sleep mode

​

    where the option is::

​

            1   -- Enable auto sleep mode

            0   -- Disable auto sleep mode

​

    Usage::

​

        # Enable auto sleep mode

        echo 1 > /debug/btmrvl/config/psmode

        echo 1 > /debug/btmrvl/config/pscmd

​

        # Disable auto sleep mode

        echo 0 > /debug/btmrvl/config/psmode

        echo 1 > /debug/btmrvl/config/pscmd

​

​

hsmode=[n], hscmd

    These commands are used to enable host sleep or wake up firmware

​

    where the option is::

​

            1   -- Enable host sleep

            0   -- Wake up firmware

​

    Usage::

​

        # Enable host sleep
