From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Warren Date: Wed, 6 Jan 2016 10:33:04 -0700 Subject: [U-Boot] [PATCH 2/3] timer: sandbox: work without device tree In-Reply-To: <1452101585-25933-1-git-send-email-swarren@wwwdotorg.org> References: <1452101585-25933-1-git-send-email-swarren@wwwdotorg.org> Message-ID: <1452101585-25933-2-git-send-email-swarren@wwwdotorg.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Stephen Warren A default invocation of sandbox U-Boot apparently uses no device tree, which means that no timer is registers, which in turn means that the sleep shell command hangs. Fix the sandbox timer code to register a device when there's no DT, just like e.g. the sandbox reset driver does. When there's no DT, the DM uclass can't initialize clock_rate from DT, so set a default value in the timer code instead.
