Subject: [PATCH 1/2] arm64: dts: st: fix sai3b unit address on stm32mp251
Date: Thu, 24 Sep 2026 19:38:09 +0000 [thread overview]
Message-ID: <20260924193759.27881-2-mateusz.nowicki@posteo.net> (raw)
In-Reply-To: <20260924193759.27881-1-mateusz.nowicki@posteo.net>
The unit address of the sai3b node, 502b0024, is the address of the
SAI_BCR1 register in the secure alias of SAI3. The reg property of the
node translates to the non-secure address 0x402b0024, which all other
SAI nodes use. Fix the unit address to match.
Fixes: bf26d75a95f1 ("arm64: dts: st: add sai support on stm32mp251")
