From 0fcfc9b2eb7f071f3aa64845d262f1e8e4f741e7 Mon Sep 17 00:00:00 2001 From: Vadim Pasternak Date: Wed, 9 Nov 2022 10:35:58 +0200 Subject: [PATCH backport 5.10 05/10] i2c: mlxcpld: Allow to configure base address of register space Allow to use configured base address. Currently driver uses constant base address of register space. On new systems this base address could be different, thus it could be passed to the driver through platform data.
