Allwinner DT changes for 4.21 - round 2 This is a small pull request for some lingering things that didn't make the first round of patches. First, the new suniv device tree included device tree headers for the clock and reset indices. These header filers are going in through the clock tree. Thus with the dt and core branches in arm-soc alone, it doesn't build. One fix is included to remove the #include statements. The defined macros aren't used yet as they were properly removed during the review phase. Second, Bluetooth using Broadcom (now Cypress) chips connected to UARTs on various boards is enabled using serdev and the updated bindings for Broadcom Bluetooth. The patch series had been sitting on the mailing lists for a month, and the driver bits were just merged on 2018/12/19.
