Based on your offline comment: ----- On going through the bootlogs before posting for I found the following errors, [ 1.091117] davinci_gpio 601000.gpio: IRQ index 2 not found [ 1.101522] davinci_gpio 601000.gpio: error -ENXIO: IRQ not populated Some issues in allocating interrupts in case of main_gpio1. I accumulated the gpio with interrupt numbers. I'll try to debug the reason behind it and update you with its status. (bootlogs of ti-sdk, also have this error). ----- I am going to drop this off my queue, please update if the fixup is some system configuration error or repost with fix. -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
