Subject: [PATCH 03/16] arm64: sysreg: Add layout for ICH_MISR_EL2
Date: Tue, 17 Dec 2024 15:13:18 +0000	[thread overview]
Message-ID: <20241217151331.934077-4-maz@kernel.org> (raw)
In-Reply-To: <20241217151331.934077-1-maz@kernel.org>

The ICH_MISR_EL2-related macros are missing a number of status
bits that we are about to handle. Take this opportunity to fully
describe the layout of that register as part of the automatic
generation infrastructure.
