This patch series updates the device tree vendor prefix for Dialog Semiconductor. Various methods are currently used throughout the kernel: 'diasemi', 'dialog' and 'dlg'. Others have also been suggested. This patch set aims to consolidate the usage of the vendor prefix to use a common standard. The prefix 'dlg' is used.
