Subject: [PATCH 2/3] arm: dts: renesas: r8a7740-armadillo800eva: Add spu clock to FSI
Date: Fri, 3 Apr 2026 18:26:54 +0700 [thread overview]
Message-ID: <20260403112655.167593-3-phucduc.bui@gmail.com> (raw)
In-Reply-To: <20260403112655.167593-1-phucduc.bui@gmail.com>
From: bui duc phuc <phucduc.bui@gmail.com>
The FSI on r8a7740 requires the SPU clock to be enabled
before accessing its registers.
Without this clock, register access may lead to a system
hang.
Describe the "spu" clock in the FSI node.
