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 converters with integrated switching FETs (DCDC):
tps65217pmic
device first appeared in
NetBSD 7.0.
tps65217pmic
driver was written by
Radoslaw Kujawa
<radoslaw.kujawa@gmail.com>.
Voltage change callback for AM335x was added by Manuel
Bouyer. White LED (backlight) support was added by
KIYOHARA Takashi.
Modifying voltage regulator parameters from user space was deliberately left unimplemented, as these parameters should only be set at the firmware or kernel level. Setting wrong parameters may result in permanent hardware damage.
The tps65217pmic
driver offers a function
that can be used to change the voltage from other kernel components
(currently used by AM335x support code).
