[PATCH v4 05/10] pinctrl: samsung: Add exynos8895 SoC pinctrl configuration
From: Ivaylo Ivanov
Date: Mon Sep 09 2024 - 07:02:13 EST
Add support for the pin-controller found on the Exynos8895 SoC
used in Samsung Galaxy S8 and S8 Plus phones.
It has a newly applied pinctrl register layer for FSYS0 with a
different bank type offset that consists of the following bit
fields:
CON: 4, DAT: 1, PUD: 2, DRV: 3, CONPDN: 2, PUDPDN: 2
