From 45f43560b270bb43369e19938192fd1f889d0298 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 29 Dec 2022 15:53:19 -0600 Subject: [PATCH] rtc: sun6i: Always export the internal oscillator [ Upstream commit cb298f538b14f3ec4b468b832239ee5e32be0f7d ] On all variants of the hardware, the internal oscillator is one possible parent for the AR100 clock. It needs to be exported so we can model that relationship correctly in the devicetree.
