Subject: [PATCH v2 07/17] arm64: dts: arm: Fix GIC child nodes
Date: Thu,  7 May 2020 12:24:20 +0100	[thread overview]
Message-ID: <20200507112430.183940-8-andre.przywara@arm.com> (raw)
In-Reply-To: <20200507112430.183940-1-andre.przywara@arm.com>

The GIC DT nodes for the Arm Ltd. boards were not fully compliant with
the DT binding, which has certain expectations about child nodes and
their size and address cells values.

Use smaller #address-cells and #size-cells values, as the binding
requests, and adjust the reg properties accordingly.
