From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon South Date: Thu, 10 Oct 2019 15:28:35 -0400 Subject: [U-Boot] [PATCH 0/1] rk3328: clk: Configure CPU clock during initialization Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This patch changes the RK3328 CRU driver so it explicitly configures the CPU clock during initialization, through a call to rk3328_configure_cpu(). Previously rk3328_configure_cpu() was implemented but not called from anywhere, which I'm assuming was unintentional. This change matches the RK3399's CRU driver (drivers/clk/rockchip/clk_rk3399.c) by - Invoking the function at the start of rkclk_init() and - Setting the CPU clock to the lowest defined frequency, 600 MHz. It yields no real functional change (the CPU clock is already set to 600 MHz at power-on) but it does make it straightforward to set a higher clock rate at compile time for systems like the ROCK64 that run reliably at higher frequencies. Tested on my ROCK64.
