Subject: [U-Boot] [PATCH 1/2] spl_spi: Read default speed and mode values from DT
Date: Thu, 8 Nov 2018 17:57:19 +0100	[thread overview]
Message-ID: <1541696240-11680-2-git-send-email-patrick.delaunay@st.com> (raw)
In-Reply-To: <1541696240-11680-1-git-send-email-patrick.delaunay@st.com>

In case of DT boot, don't read default speed and mode for SPI from
CONFIG_*, instead read from DT node.
