Subject: [PATCH v3 1/4] arm64: dts: ti: k3-j721e: Add MCSPI nodes
Date:   Tue, 21 Mar 2023 13:58:24 +0530
Message-ID: <20230321082827.14274-2-vaishnav.a@ti.com>
In-Reply-To: <20230321082827.14274-1-vaishnav.a@ti.com>

J721E has 8 MCSPI instances in the main domain and 3 instances
in the MCU domain. Add the DT nodes for all the 11 instances and
keep them disabled. MAIN_MCSPI4 is connected as a slave to MCU_MCSPI2
by default at power-up, MAIN_MCSPI4 and MCU_MCSPI2 are not pinned out
externally.

V2->V3:
 * Update commit message to mention internal MCSPI loopback.

V1->V2: 
  * Combine main, mcu domain, MCSPI node addition changes
  to single commit.
