From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Sat, 1 Oct 2016 20:04:51 -0600 Subject: [U-Boot] [PATCH v2 2/3] rockchip: rk3399: Move rockchip_get_cru() out of the driver In-Reply-To: <1475373892-20780-1-git-send-email-sjg@chromium.org> References: <1475373892-20780-1-git-send-email-sjg@chromium.org> Message-ID: <1475373892-20780-2-git-send-email-sjg@chromium.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This function is called from outside the driver. It should be placed into common SoC code. Move it. Also rename the driver symbol to be more consistent with the other rockchip clock drivers.
