6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Lezcano daniel.lezcano@linaro.org
[ Upstream commit 0b781f527d6f99e68e5b3780ae03cd69a7cb5c0c ]
The driver uses the raw_readl() and raw_writel() functions. Those are not for MMIO devices. Replace them with readl() and writel()
[ dlezcano: Fixed typo in the subject s/reald/readl/ ]
