Subject: rtc: ds1390: Add OF device ID table
X-Git-Tag: v4.19~2108^2~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3ba2c76a9d3a339cd1b77e88915680ae2e9ac2da;p=platform%2Fkernel%2Flinux-rpi.git

rtc: ds1390: Add OF device ID table

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. Worse, the compatible is documented but
doesn't currently match the driver.

Add the proper compatible to the driver.
