Subject: [PATCH] arm64: dts: ti: k3-j7200-som-p0: Add TP6594 family PMICs
Date: Fri, 27 Oct 2023 10:28:52 +0200 [thread overview]
Message-ID: <20231027082852.2922552-1-thomas.richard@bootlin.com> (raw)
From: Esteban Blanc <eblanc@baylibre.com>
This patch adds support for TPS6594 PMIC family on wakup I2C0 bus.
Theses devices provides regulators (bucks and LDOs), but also
GPIOs, a RTC, a watchdog, an ESM (Error Signal Monitor)
which monitors the SoC error output signal, and a PFSM
(Pre-configurable Finite State Machine) which manages the
operational modes of the PMIC.
