[ 11.136543] calling pm_genpd_debug_init+0x0/0x60 @ 1 [ 11.141602] initcall pm_genpd_debug_init+0x0/0x60 returned 0 after 11 usecs [ 11.148558] calling genpd_poweroff_unused+0x0/0x84 @ 1 <hang> In some cases, the rk3399 should turn off the gmac power domain to save power if some boards didn't register the gmac device node for rk3399. Then, rk3399 need to make sure the gmac's pclk enabled if we need operate the gmac power domain.
