Laxman Dewangan	d2d5437bdf	regulator: max8973: add support for junction thermal warning ... The driver MAX8973 supports the driver for Maxim PMIC MAX77621. MAX77621 supports the junction temp warning at 120 degC and 140 degC which is configurable. It generates alert signal when junction temperature crosses these threshold. MAX77621 does not support the continuous temp monitoring of junction temperature. It just report whether junction temperature crossed the threshold or not. Add support to - Configure junction temp warning threshold via DT property to generate alert when it crosses the threshold. - Add support to interrupt the host from this device when alert occurred. - read the junction temp via thermal framework.

Laxman Dewangan	69eb0980ab	regulator: max8973: add mechanism to enable/disable through GPIO ... MAX8973 supports the voltage output enable/disable through its EN pin. This EN pin can be connected through GPIO from host processor. Add support to provide GPIO number from platform/DT and if it is valid GPIO then enable external control default.

Laxman Dewangan	5928f53896	regulator: max8973: add regulator driver support ... The MAXIM MAX8973 high-efficiency, three phase, DC-DC step-down switching regulator delievers up to 9A of output current. Each phase operates at a 2MHz fixed frequency with a 120 deg shift from the adjacent phase, allowing the use of small magnetic component. Add regulator driver for this device.
