Subject: [PATCH v3 12/19] PM / devfreq: rockchip-dfi: Handle LPDDR4X
Date: Thu, 16 Feb 2023 11:36:17 +0100 [thread overview]
Message-ID: <20230216103624.591901-13-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20230216103624.591901-1-s.hauer@pengutronix.de>
In the DFI driver LPDDR4X can be handled in the same way as LPDDR4. Add
the missing case.
