Subject: [PATCH v4 0/2] Add support for TPS25750
Date: Sun, 20 Aug 2023 15:32:25 -0400 [thread overview]
Message-ID: <cover.1692559293.git.alkuor@gmail.com> (raw)
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
v4:
- PATCH 1: No change
- PATCH 2: Fix comments style and drop of_match_ptr
v3:
- PATCH 1: Fix node name
- PATCH 2: Upload tps25750 driver patch
v2:
