Subject: [PATCH 0/4] Add Qualcomm's IPQ9650 APSS Clock Driver Support
Date: Wed, 07 Oct 2026 12:20:43 +0530	[thread overview]
Message-ID: <20261007-ipq9650_apss_clk-v1-0-fd4c2b3cbdea@oss.qualcomm.com> (raw)

The APSS clock controller on IPQ9650 provides the CPU and L3 clocks. The
four Cortex-A55 cores (silver), the Cortex-A78 core (gold) and the L3
are each clocked by their own Zonda PLL, selected through a glitch-free mux
whose parents are XO, GPLL0 and the corresponding PLL. Since the L3 has
to scale along with the CPUs, the controller also registers an icc-clk
provider in which both CPU clusters vote on the L3 clock.
