Message-Id: <20240906-j784s4-tps6594-bootph-v1-2-c5b58d43bf04@redhat.com> Date: Fri, 06 Sep 2024 16:21:03 -0500 From: Andrew Halaney <ahalaney@...hat.com> To: Nishanth Menon <nm@...com>, Vignesh Raghavendra <vigneshr@...com>, Tero Kristo <kristo@...nel.org>, Rob Herring <robh@...nel.org>, Krzysztof Kozlowski <krzk+dt@...nel.org>, Conor Dooley <conor+dt@...nel.org> Cc: Keerthy <j-keerthy@...com>, Neha Malcom Francis <n-francis@...com>, Eric Chanudet <echanude@...hat.com>, Enric Balletbo <eballetb@...hat.com>, Udit Kumar <u-kumar1@...com>, linux-arm-kernel@...ts.infradead.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org, Andrew Halaney <ahalaney@...hat.com> Subject: [PATCH RFC/RFT 2/2] arm64: dts: ti: k3-am69-sk: Mark tps659413 and children as bootph-all In order for the MCU domain to access this PMIC and its children in u-boot SPL, the nodes need to be marked appropriately otherwise they are not seen by SPL. This is necessary if the MCU domain is to program the TPS6594 MCU ESM state machine, which is required to wire up the watchdog in a manner that will reset the board.
