Subject: [PATCH v4 1/6] sysreset: qemu virt: Use __raw_writel()
Date: Mon, 13 Apr 2026 18:22:35 +0900 [thread overview]
Message-ID: <20260413092240.3719260-2-daniel@thingy.jp> (raw)
In-Reply-To: <20260413092240.3719260-1-daniel@thingy.jp>
The virt ctrl register seems to be native endian, currently this driver
uses writel(), which works by luck because its currently broken on m68k.
Use __raw_writel() instead to avoid breaking this driver when the
endianness of writel() is fixed.
