Subject: [PATCH net-next 1/3] dt-bindings: mfd: syscon: add ti,am654-gtc
Date: Tue, 10 Nov 2026 11:24:01 +0700 [thread overview]
Message-ID: <42bbc4a03679958f2ed4e195acea99fb57c68fd6.1794284248.git.jjc@jclark.com> (raw)
In-Reply-To: <cover.1794284248.git.jjc@jclark.com>
Add a compatible for the CFG0 register frame of the Global Timebase
Counter (GTC) on TI K3 SoCs. The GTC is the system counter that the Arm
cores read as the architected counter. CFG0 holds GTC_CFG0_PUSHEVT,
which selects the counter bit that the GTC exports as its push event
output; the CPTS driver writes to that register to provide hardware
cross-timestamps.
