Subject: [PATCH v2 4/7] hw/char/exynos4210_uart: Implement post_load function
Date: Sat, 18 Jan 2020 08:42:26 -0800 [thread overview]
Message-ID: <20200118164229.22539-5-linux@roeck-us.net> (raw)
In-Reply-To: <20200118164229.22539-1-linux@roeck-us.net>
After restoring a VM, serial parameters need to be updated to reflect
restored register values. Implement a post_load function to handle this
situation.
Signed-off-by: Guenter Roeck <linux@roeck-us.net>

v4: Additional patch to implement post-load functionality
in exynos uart driver. Required for next patch in series.
