Subject: [PATCH devicetree 2/2] arm64: dts: ls1028a-rdb: Add a spidev node for the mikroBUS
Date: Fri, 20 Mar 2020 18:13:46 +0200 [thread overview]
Message-ID: <20200320161346.14155-3-olteanv@gmail.com> (raw)
In-Reply-To: <20200320161346.14155-1-olteanv-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
From: Vladimir Oltean <vladimir.oltean-3arQi8VN3Tc@public.gmane.org>
For debugging, it is useful to have access to the DSPI controller
signals. On the reference design board, these are exported to either the
mikroBUS1 or mikroBUS2 connector (according to the CPLD register
BRDCFG3[SPI3]).
