This patchset adds initial support for the Texas Instruments TPS25990
eFuse. The TPS25990 is an integrated, high-current circuit protection and
power management device. TPS25895 may be stacked on the TPS25990 for
higher currents.
This patchset provides basic telemetry support for the device.
On boot, the device is write protected. Limits can be changed in sysfs
after removing the write protection, through debugfs. Limits will be
restored to the default value device on startup, unless saved to NVM.
Writing the NVM is not supported by the driver at the moment.
