Subject: [PATCH 3/4] hw/char: Add QOM property for STM32L4x5 USART clock frequency
Date: Tue, 7 May 2024 20:55:40 +0200 [thread overview]
Message-ID: <20240507185854.34572-4-ines.varhol@telecom-paris.fr> (raw)
In-Reply-To: <20240507185854.34572-1-ines.varhol@telecom-paris.fr>
This QOM property will be used to check the clock frequency from QTests.
Signed-off-by: Inès Varhol <ines.varhol@telecom-paris.fr>
