clk: qcom: a53pll/mux: Use unique clock name
Different from MSM8916 which has only one a53pll/mux clock, MSM8939 gets three for Cluster0 (little cores), Cluster1 (big cores) and CCI (Cache Coherent Interconnect). That said, a53pll/mux clock needs to be named uniquely. Append @unit-address of device node to the clock name, so that a53pll/mux will be named like below on MSM8939. a53pll@b016000 a53pll@b116000 a53pll@b1d0000 a53mux@b1d1000 a53mux@b011000 a53mux@b111000 Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Link: https://lore.kernel.org/r/20210704024032.11559-3-shawn.guo@linaro.org Signed-off-by: Stephen Boyd <sboyd@kernel.org>
