From fc64f1ce292d0adb9ac3c8b6e372412bb6aa3052 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andr=C3=A9=20Draszik?= Date: Wed, 10 Jul 2024 11:36:20 +0100 Subject: [PATCH] usb: typec: tcpm/tcpci_maxim: use GENMASK() for TCPC_VENDOR_ADC_CTRL1 register MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Convert register TCPC_VENDOR_ADC_CTRL1 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.
