From adfda0bb86183ac3b5bb0c76813bfca0fe6d5166 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Sun, 24 Apr 2022 11:26:22 -0500 Subject: [PATCH] drm/sun4i: hdmi: Use more portable I/O helpers readsb/writesb are unavailable on some architectures. In preparation for removing the Kconfig architecture dependency, switch to the equivalent but more portable ioread/write8_rep helpers.
