From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christoph Muellner Date: Tue, 7 May 2019 10:49:13 +0200 Subject: [U-Boot] [PATCH 1/2] rk3399: Restore broken USB3 DTS description. Message-ID: <20190507084914.47700-1-christoph.muellner@theobroma-systems.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This is a partial revert of commit 0a09f2f1173d ("rockchip: Adjust rk3399 device tree to be closer to linux"). Harmonizing the rk3399.dtsi with the one from Linux is a good idea. However, this is only true if the information within that file can be used by U-Boot. Before the named commit USB3 was working fine, after the commit USB3 was broken on all RK3399 boards. This commit reverts the USB3 changes to the original ones, which provide the required information for the corresponding drivers in the U-Boot tree.
