Subject: [PATCH v2 05/19] PM / devfreq: rockchip-dfi: dfi store raw values in counter struct
Date: Wed,  8 Feb 2023 10:38:16 +0100	[thread overview]
Message-ID: <20230208093830.143284-6-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20230208093830.143284-1-s.hauer@pengutronix.de>

When adding perf support to the DFI driver the perf part will
need the raw counter values, so move the fixed * 4 factor to
rockchip_dfi_get_event().
