Recent PTP-specific cpsw driver changes started exposing an issue on at at least j5eco-evm: Unhandled fault: external abort on non-linefetch (0x1008) at 0xf0169004 ... (davinci_mdio_runtime_suspend) from [<c063f2a4>] (__rpm_callback+0x84/0x154) (__rpm_callback) from [<c063f394>] (rpm_callback+0x20/0x80) (rpm_callback) from [<c063f4f0>] (rpm_suspend+0xfc/0x6ac) (rpm_suspend) from [<c0640af0>] (pm_runtime_work+0x88/0xa4) (pm_runtime_work) from [<c0155338>] (process_one_work+0x228/0x568) ... Let's fix the issue by using the correct the mdio clock as suggested by Grygorii Strashko <grygorii.strashko@ti.com>. The DM814_ETHERNET_CPGMAC0_CLKCTRL clock is the interconnect target module clock and managed by ti-sysc.
