Subject: [PATCH v2 3/5] dt-bindings: mfd: syscon: add TI's opp table compatible
Date: Wed, 12 Jun 2024 18:17:36 -0500 [thread overview]
Message-ID: <20240612-ti-opp-updates-v2-3-422b6747a254@ti.com> (raw)
In-Reply-To: <20240612-ti-opp-updates-v2-0-422b6747a254@ti.com>
The JTAG_USER_ID_USERCODE efuse address, which is located inside the
WKUP_CTRL_MMR0 range holds information to identify the speed grades of
various components on TI's K3 SoCs. Add a compatible to allow the
cpufreq driver to obtain the data to limit the maximum frequency for the
CPUs under Linux control.
