Subject: [PATCH 3/5] arm64: boot: dts: ti: k3-am68-sk-base-board: Add LP8733 and TPS6287 nodes
Date: Tue, 7 May 2024 17:51:56 +0530 [thread overview]
Message-ID: <20240507122158.3739291-4-n-francis@ti.com> (raw)
In-Reply-To: <20240507122158.3739291-1-n-francis@ti.com>
Add DTS node for LP87334E PMIC and two TPS6287x high current buck
converters.
LP87334E is responsible for supplying power to the MCU and MAIN domains
as well as to LPDDR4. The two TPS6287x supply power to the MAIN
domain for AVS and other core supplies.
