Subject: [PATCH 2/2] arm64: dts: qcom: ipq8074: Add CMN PLL
Date: Sat, 24 Oct 2026 12:33:10 +0200 [thread overview]
Message-ID: <20261024103401.761125-2-robimarko@gmail.com> (raw)
In-Reply-To: <20261024103401.761125-1-robimarko@gmail.com>
Add the CMN PLL node, it will be used to feed the required fixed clocks
to networking subsystem.
CMN PLL provides bias_pll_cc_clk and bias_pll_nss_noc_clk to GCC.
