Date: Sun, 25 Jun 2023 23:25:25 +0300	[thread overview]
Message-ID: <20230625202547.174647-5-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20230625202547.174647-1-dmitry.baryshkov@linaro.org>

Define bindings for the Qualcomm Krait CPU and L2 clock controller. This
device is used on old Qualcomm SoCs (APQ8064, MSM8960) and supports up
to 4 core clocks and a separate L2 clock. Furthermore, L2 clock is
represented as the interconnect to facilitate L2 frequency scaling
together with scaling the CPU frequencies.
