From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lukasz Majewski Date: Fri, 17 May 2019 00:10:35 +0200 Subject: [U-Boot] [PATCH v4 06/13] clk: Provide struct clk for fixed rate clock (clk_fixed_rate.c) In-Reply-To: <20190516221042.3583-1-lukma@denx.de> References: <20190516221042.3583-1-lukma@denx.de> Message-ID: <20190516221042.3583-7-lukma@denx.de> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Up till now the fixed rate clock ('osc') has been added to UCLASS_CLK without declaring struct clk. As a result it was only accessible by iterating the udevice's uclass list. This is a problem for clock code, which operates on pointers to struct clk (like clk_get_rate()), not udevices. After this change struct clk is accessible from udevice and udevice from struct clk.
