Subject: [PATCH 6.6.y] arm64: dts: ti: k3-j721e-sk: Add DT nodes for power regulators
Date: Fri, 6 Jun 2025 14:31:28 +0530	[thread overview]
Message-ID: <20250606090128.2268237-1-y-abhilashchandra@ti.com> (raw)
In-Reply-To: <2025060241-numbly-remarry-d1a6@gregkh>

Add device tree nodes for two power regulators on the J721E SK board.
vsys_5v0: A fixed regulator representing the 5V supply output from the
LM61460 and vdd_sd_dv: A GPIO-controlled TLV71033 regulator.
