[PATCH 2/7] arm64: arch_timer: add dt binding for hisilicon-161010101 erratum

Show all headers | View raw

From: Ding Tianhong <dingtianhong@huawei.com>

This erratum describes a bug in logic outside the core, so MIDR can't be
used to identify its presence, and reading an SoC-specific revision
register from common arch timer code would be awkward.  So, describe it
in the device tree.
