However, on MSM8939 three APCS clocks need to be registered for cluster0 (little cores), cluster1 (big cores) and CCI (Cache Coherent Interconnect). That said, we will need to register 3 qcom-apcs-msm8916-clk devices. Let's use PLATFORM_DEVID_AUTO rather than PLATFORM_DEVID_NONE for platform_device_register_data() call. Otherwise, the second APCS clock registration will fail due to duplicate device name. [ 0.519657] sysfs: cannot create duplicate filename '/bus/platform/devices/qcom-apcs-msm8916-clk' ...
