From c58ddd297fb903e11b0fcae0c0d38106125c1b58 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 31 Mar 2021 18:48:50 +0300 Subject: =?UTF-8?q?mfd:=20intel=5Fquark=5Fi2c=5Fgpio:=20Convert=20I=C2=B2C?= =?UTF-8?q?=20to=20use=20software=20nodes?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The driver can provide a software node group instead of passing legacy platform data. This will allow to drop the legacy platform data structures along with unifying a child device driver to use same interface for all property providers, i.e. Device Tree, ACPI, and board files.
