Subject: [RFC PATCH v1 10/21] clocksource/timer-riscv: ACPI: Add timer_cannot_wakeup_cpu
Date: Thu,  3 Aug 2023 23:29:05 +0530	[thread overview]
Message-ID: <20230803175916.3174453-11-sunilvl@ventanamicro.com> (raw)
In-Reply-To: <20230803175916.3174453-1-sunilvl@ventanamicro.com>

The timer capability to wakeup the cpu irrespective of its
idle state is provided by the flag in RHCT. Update the timer
code to set this flag.
