Subject: [PATCH v2] arm64: dts: ti: k3-am62-main: Remove power-domains from crypto node
Date: Wed, 14 Jun 2023 15:16:56 +0530 [thread overview]
Message-ID: <20230614-sa3ul-v2-1-3a832b82339c@ti.com> (raw)
Only SYSFW has control of SA3UL power.
From SYSFW 08.04.00.002, for security reasons, device ID for power
management of SA3UL has been removed.
"power-domains" property in crypto node tries to access
the SA3UL, for which it gets NACK and hence, SA3UL driver doesn't
probe properly.
Fixes: 8af893654c02 ("arm64: dts: ti: k3-am62-main: Enable crypto accelerator")
