Subject: [PATCH v3 3/4] arm64: dts: ti: k3-j721s2: Add MCSPI nodes
Date: Tue, 21 Mar 2023 13:58:26 +0530 [thread overview]
Message-ID: <20230321082827.14274-4-vaishnav.a@ti.com> (raw)
In-Reply-To: <20230321082827.14274-1-vaishnav.a@ti.com>
J721S2 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.
Signed-off-by: Vaishnav Achath <vaishnav.a@ti.com>
Reviewed-by: Keerthy <j-keerthy@ti.com>
---
V2->V3:
* Add Keerthy's Reviewed-by.
* Update commit message to mention internal MCSPI loopback.
V1->V2:
* Combine main, mcu domain, MCSPI node addition changes
to single commit.
