Subject: [PATCH v5 07/15] clk: qcom: gcc-ipq806x: add additional freq nss cores
Date:   Thu, 24 Feb 2022 17:48:23 +0100
Message-Id: <20220224164831.21475-8-ansuelsmth@gmail.com>

Ipq8065 SoC (an evolution of ipq8064 SoC) contains nss cores that can be
clocked to 800MHz. Add these missing freq to the gcc driver.
Set the freq_tbl for the ubi32_cores to the correct values based on the
machine compatible.
