Hello, I am trying to get HDMI work with DT on my VAR-STK-OM44 (4460) board. But during kernel boot I get the following message: [ 0.953796] ------------[ cut here ]------------ [ 0.953826] WARNING: CPU: 0 PID: 1 at drivers/video/omap2/dss/dss.c:483 dss_set_fck_rate+0x7c/0x8c() [ 0.953826] clk rate mismatch: 153600000 != 170666666 [ 0.953857] Modules linked in: [ 0.953857] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.15.0-rc1-00030-gef9175d699c2 #25 [ 0.953918] [<c0014f68>] (unwind_backtrace) from [<c0011c2c>] (show_stack+0x10/0x14) [ 0.953918] [<c0011c2c>] (show_stack) from [<c05a7774>] (dump_stack+0x84/0x94) [ 0.953948] [<c05a7774>] (dump_stack) from [<c0036e18>] (warn_slowpath_common+0x70/0x8c) [ 0.953979] [<c0036e18>] (warn_slowpath_common) from [<c0036e64>] (warn_slowpath_fmt+0x30/0x40) [ 0.953979] [<c0036e64>] (warn_slowpath_fmt) from [<c02a9928>] (dss_set_fck_rate+0x7c/0x8c) [ 0.954010] [<c02a9928>] (dss_set_fck_rate) from [<c083b7f8>] (omap_dsshw_probe+0x21c/0x3a0) [ 0.954040] [<c083b7f8>] (omap_dsshw_probe) from [<c030bc38>] (platform_drv_probe+0x18/0x48) [ 0.954040] [<c030bc38>] (platform_drv_probe) from [<c030a4bc>] (driver_probe_device+0x124/0x240) [ 0.954071] [<c030a4bc>] (driver_probe_device) from [<c030a6b0>] (__driver_attach+0x94/0x98) [ 0.954101] [<c030a6b0>] (__driver_attach) from [<c0308a94>] (bus_for_each_dev+0x60/0x94) [ 0.954101] [<c0308a94>] (bus_for_each_dev) from [<c0309c6c>] (bus_add_driver+0x14c/0x1f4) [ 0.954132] [<c0309c6c>] (bus_add_driver) from [<c030aca4>] (driver_register+0x78/0xf8) [ 0.954132] [<c030aca4>] (driver_register) from [<c030bc90>] (platform_driver_probe+0x20/0xa8) [ 0.954162] [<c030bc90>] (platform_driver_probe) from [<c083b54c>] (omap_dss_init+0x24/0xb4) [ 0.954162] [<c083b54c>] (omap_dss_init) from [<c000897c>] (do_one_initcall+0xf8/0x148) [ 0.954193] [<c000897c>] (do_one_initcall) from [<c080fc58>] (kernel_init_freeable+0x13c/0x1dc) [ 0.954223] [<c080fc58>] (kernel_init_freeable) from [<c05a2a80>] (kernel_init+0xc/0xe8) [ 0.954223] [<c05a2a80>] (kernel_init) from [<c000e2c8>] (ret_from_fork+0x14/0x2c) [ 0.954254] ---[ end trace ce91e7215ac78433 ]--- [ 0.954345] OMAP DSS rev 4.0 [ 0.956970] connector-hdmi connector.10: failed to find video source [ 0.957031] connector-hdmi: probe of connector.10 failed with error -22 [ 0.959167] omapfb omapfb: no displays [ 0.961547] omapfb omapfb: failed to setup omapfb [ 0.961578] platform omapfb: Driver omapfb requests probe deferral Googling turned up this thread: https://lkml.org/lkml/2014/1/27/285 So I guess one possible explanation would be a bug in the omap4460 clock data.
