[PATCH 07/15] usb: typec: tcpci: use GENMASK() for TCPC_TRANSMIT register fields
From: André Draszik
Date: Wed Jul 10 2024 - 06:41:11 EST
Convert all fields from register TCPC_TRANSMIT to using GENMASK() and
FIELD_PREP() so as to keep using a similar approach throughout the code
base and make it arguably easier to read.
