Subject: [PATCH v4 0/2] Add support for TPS25750
TPS25750 is USB Type-C and PD controller. The device is
highly configurable using App Customization online Tool
developed by TI to generate loadable binary.
TPS25750 supports three modes; PTCH, APP, and BOOT. A configuration
can only be applied when the controller is on PTCH mode.
The controller attempts to load a configuration from EEPROM on
I2Cm bus. If no EEPROM is detected, then the driver tries to load
a configuration on I2Cs bus using a firmware file defined
in DT.
The driver implements the binary loading sequence which
can be found on pg.53 in TPS25750 Host Interface Technical
Reference Manual (Rev. A) https://tinyurl.com/y9rkhu8a
The driver only supports resume pm callback as power management is
automatically controlled by the device. See pg.47 in TPS25750
datasheet https://tinyurl.com/3vfd2k43
