NAME
     tps65217pmic -- Texas Instruments TPS65217 Power Management IC driver

SYNOPSIS
     tps65217pmic0 at iic? addr 0x24

DESCRIPTION
     The tps65217pmic driver provides minimal support for the TPS65217 chip
     and allows reporting regulated voltages through the envsys(4) API.

     The TPS65217 consists of low-dropout regulators (LDO) and step-down con-
     verters with integrated switching FETs (DCDC):
        LDO1: 1.0V - 3.3V
        LDO2: 0.9V - 3.3V
        LDO3: 1.5V - 3.3V
        LDO4: 1.5V - 3.3V
        DCDC1: 0.9V - 1.8V
        DCDC2: 0.9V - 3.3V
        DCDC1: 0.9V - 1.5V

SEE ALSO
     envsys(4)

HISTORY
     The tps65217pmic device first appeared in NetBSD 7.0.

AUTHORS
     The tps65217pmic driver was written by Radoslaw Kujawa
     <radoslaw.kujawa@gmail.com>.

CAVEATS
     The driver can only report current voltage regulator settings.  It can
     not measure the real voltage, as the TPS65217 chip lacks hardware to do
     that.

     Modifying voltage regulator parameters was deliberately left unimple-
     mented, as these parameters should only be set at the firmware level.
     Setting wrong parameters may result in permanent hardware damage.

BUGS
     Battery, interrupt and WLED (backlight) support is not implemented.

NetBSD 7.0                      April 29, 2013                      NetBSD 7.0
