Subject: [PATCH 2/7] ARM: dts: stm32: fix slew-rate of USART2 on stm32mp15xx-dkx
Date: Mon, 27 Mar 2023 17:39:38 +0200 [thread overview]
Message-ID: <20230327153943.275124-1-valentin.caron@foss.st.com> (raw)
In-Reply-To: <20230327152948.274743-1-valentin.caron@foss.st.com>
On stm32mp15xx-dkx boards:
- Fix slew-rate of USART 2 to 0 like other USARTs, because frequency of
USART pins doesn't exceed 10Mhz.
