Hi All, I noticed recently error logs when booting Odroid HC1 (Exynos5422) on exynos_defconfig, 5.4.0-rc1-next-20191004: [ 5.168786] exynos-bus: new bus device registered: soc:bus_wcore ( 84000 KHz ~ 400000 KHz) [ 5.177022] exynos-bus: new bus device registered: soc:bus_noc ( 67000 KHz ~ 100000 KHz) [ 5.184705] exynos-bus: new bus device registered: soc:bus_fsys_apb (100000 KHz ~ 200000 KHz) [ 5.192903] exynos-bus: new bus device registered: soc:bus_fsys (100000 KHz ~ 200000 KHz) [ 5.201414] exynos-bus: new bus device registered: soc:bus_fsys2 ( 75000 KHz ~ 150000 KHz) [ 5.209986] exynos-bus: new bus device registered: soc:bus_mfc ( 96000 KHz ~ 333000 KHz) [ 5.217931] exynos-bus: new bus device registered: soc:bus_gen ( 89000 KHz ~ 267000 KHz) [ 5.225222] exynos-bus soc:bus_wcore: dev_pm_opp_set_rate: failed to find current OPP for freq 532000000 (-34) [ 5.225975] exynos-bus: new bus device registered: soc:bus_peri ( 67000 KHz ~ 67000 KHz) [ 5.238824] exynos-bus soc:bus_noc: dev_pm_opp_set_rate: failed to find current OPP for freq 111000000 (-34) [ 5.245719] exynos-bus: new bus device registered: soc:bus_g2d ( 84000 KHz ~ 333000 KHz) [ 5.252653] exynos-bus soc:bus_fsys_apb: dev_pm_opp_set_rate: failed to find current OPP for freq 222000000 (-34) [ 5.263518] exynos-bus: new bus device registered: soc:bus_g2d_acp ( 67000 KHz ~ 267000 KHz) [ 5.280650] exynos-bus: new bus device registered: soc:bus_jpeg ( 75000 KHz ~ 300000 KHz) [ 5.288827] exynos-bus: new bus device registered: soc:bus_jpeg_apb ( 84000 KHz ~ 167000 KHz) [ 5.296957] exynos-bus: new bus device registered: soc:bus_disp1_fimd (120000 KHz ~ 200000 KHz) [ 5.305939] exynos-bus: new bus device registered: soc:bus_disp1 (120000 KHz ~ 300000 KHz) [ 5.314036] exynos-bus: new bus device registered: soc:bus_gscl_scaler (150000 KHz ~ 300000 KHz) [ 5.323090] exynos-bus: new bus device registered: soc:bus_mscl ( 84000 KHz ~ 400000 KHz) You can see that Exynos devfreq was trying to set 532000000 Hz for wcore, 111000000 for noc and 222000000 for fsys_apb. These are higher frequencies than we have in DTSI. Any ideas why? It does not look normal... Best regards, Krzysztof
