- From e567e58d6819adc002c57b81e16b88da24d3b4aa Mon Sep 17 00:00:00 2001
- From: Pierre Gondois <[email protected]>
- Date: Tue, 22 Nov 2022 17:32:07 +0100
- Subject: [PATCH] arm64: dts: Update cache properties for broadcom
- The DeviceTree Specification v0.3 specifies that the cache node
- 'compatible' and 'cache-level' properties are 'required'. Cf.
- s3.8 Multi-level and Shared Cache Nodes
- The 'cache-unified' property should be present if one of the
- properties for unified cache is present ('cache-size', ...).
- Update the Device Trees accordingly.
