+=======================================================================
+ README for btmrvl driver
+=======================================================================
+
+
+All commands are used via debugfs interface.
+
+=====================
+Set/get driver configurations:
+
+Path: /debug/btmrvl/config/
+
+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
+ echo 1 > /debug/btmrvl/config/hsmode
+ echo 1 > /debug/btmrvl/config/hscmd
+
+ # Wake up firmware
+ echo 0 > /debug/btmrvl/config/hsmode
+ echo 1 > /debug/btmrvl/config/hscmd
+
+
+======================
+Get driver status:
+
+Path: /debug/btmrvl/status/
+
+Usage:
+ cat /debug/btmrvl/status/<args>
+
+where the args are:
+
+curpsmode
+ This command displays current auto sleep status.
+
+psstate
+ This command display the power save state.
+
+hsstate
+ This command display the host sleep state.
+
+txdnldrdy
+ This command displays the value of Tx download ready flag.
+
+
+=====================
+
+Use hcitool to issue raw hci command, refer to hcitool manual
+
+ Usage: Hcitool cmd <ogf> <ocf> [Parameters]
+
+ Interface Control Command
+ hcitool cmd 0x3f 0x5b 0xf5 0x01 0x00 --Enable All interface
+ hcitool cmd 0x3f 0x5b 0xf5 0x01 0x01 --Enable Wlan interface
+ hcitool cmd 0x3f 0x5b 0xf5 0x01 0x02 --Enable BT interface
+ hcitool cmd 0x3f 0x5b 0xf5 0x00 0x00 --Disable All interface
+ hcitool cmd 0x3f 0x5b 0xf5 0x00 0x01 --Disable Wlan interface
+ hcitool cmd 0x3f 0x5b 0xf5 0x00 0x02 --Disable BT interface
