Adaptive Voltage Scaling is a technology used in TI SoCs to optimize
the operating voltage based on characterization data written to efuse
during production.
Add support for Adaptive Voltage scaling class 0 support
for AM6 family of devices. Adaptive voltage scaling class 0
implies that optimized voltage values for a particular OPP
of a particular voltage domain are read from Efuse and programmed
on the pmic/regulator.
Tested on AM654-EVM for MPU @800 MHz.
Changes in v2:
* Avoided creation of new uclass. AVS driver is now under misc.
Keerthy (2):
arm: mach-k3: am6_init: Initialize AVS class 0
clk: clk-ti-sci: Notify AVS driver upon setting clock rate
Tero Kristo (8):
misc: k3_avs: add driver for K3 Adaptive Voltage Scaling Class 0
power: regulator: tps6236x: add support for tps6236x regulators
arm: dts: k3-am65: Add VTM node
arm: dts: k3-am654-r5-base-board: enable wkup_i2c0 driver for spl
arm: dts: k3-am654-r5-base-board: add supply rail for MPU
arm: dts: k3-am654-r5-base-board: enable wkup_vtm0 node and link in
supplies
configs: am65x_evm_r5_defconfig: Enable TPS62363 regulator support
