DESCRIPTION    [Toc]    [Back]

     The tctrl driver provides control over many functions on the
Tadpole
     SPARCbook  3  series laptops, via their TS102 chip.  The microcontroller is
     used to power the TFT display down when the  laptop  lid  is
closed and when
     the  screen  is blanked by the pninek(4) or pnozz(4) driver.
The tctrl is
     also used to power the laptop off when the reboot(2)  system
call is used
     with  the  RB_POWERDOWN flag is set.  The PCMCIA part of the
controller is
     managed by the tslot(4) driver.
