From a665b2c1d28403e385054447cc319095527bedde Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 7 Sep 2020 13:18:29 +0100 Subject: arm64: dts: hisilicon: Fix SP805 clocks The SP805 DT binding requires two clocks to be specified, but Hisilicon platform DTs currently only specify one clock. In practice, Linux would pick a clock named "apb_pclk" for the bus clock, and the Linux and U-Boot SP805 driver would use the first clock to derive the actual watchdog counter frequency. Since currently both are the very same clock, we can just double the clock reference, and add the correct clock-names, to match the binding.
