Subject: [PATCH v5 04/11] arm64: dts: qcom: shikra: Add cpufreq-hw, EPSS L3 interconnect and OPP tables
Date: Thu, 02 Jul 2026 15:20:46 +0530	[thread overview]
Message-ID: <20260702-shikra-dt-m1-v5-4-f911ac92720c@oss.qualcomm.com> (raw)
In-Reply-To: <20260702-shikra-dt-m1-v5-0-f911ac92720c@oss.qualcomm.com>

Add cpufreq-hw node to support cpufreq scaling on Qualcomm Shikra SoCs.
Also, add Epoch Subsystem (EPSS) L3 interconnect provider node and OPP
tables required to scale DDR and L3 per freq-domain on Shikra SoC.
