Subject: [PATCH v2 2/8] spi: stm32: do not mandate cs_gpio
Date: Fri, 5 Feb 2021 19:59:26 +0100 [thread overview]
Message-ID: <1612551572-495-3-git-send-email-alain.volmat@foss.st.com> (raw)
In-Reply-To: <1612551572-495-1-git-send-email-alain.volmat@foss.st.com>
CS gpios is not mandatory, the driver should allow working
even when CS are not given.
