Message-Id: <20220302211113.4003816-12-clabbe@baylibre.com> Date: Wed, 2 Mar 2022 21:11:06 +0000 From: Corentin Labbe <clabbe@...libre.com> To: heiko@...ech.de, herbert@...dor.apana.org.au, robh+dt@...nel.org Cc: devicetree@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-crypto@...r.kernel.org, linux-kernel@...r.kernel.org, linux-rockchip@...ts.infradead.org, john@...anate.com, Corentin Labbe <clabbe@...libre.com> Subject: [PATCH v2 11/18] crypto: rockhip: do not handle dma clock The DMA clock is handled by the DMA controller, so the crypto does not have to touch it.
