From 40f60ee1d33c0072293863d0c9d3a3f60004870b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 27 Sep 2021 14:02:40 +0100 Subject: [PATCH] rtc: mcp795: Add SPI ID table [ Upstream commit 3109151c47343c80300177ec7704e0757064efdc ] Currently autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding an id_table listing the SPI IDs for everything.
