It solves a bug on IGEPv2 boards. I know the trend is to move away from board code. I'll start working on an device tree for the IGEPv2 but it will take some time until is ready (and I'm not sure if all the OMAP3 support is already present on DT). So could you please take bug fixes for the board code in the meantime?

Yes seems like something for the v3.6-rc series.

According to the IGEPv2 Rev.C data-sheet the LAN9221i pin 14 (IRQ) is connected to the OMAP3730 mcspi1_cs2 pin. Since this omap mux pin acts as an IRQ line, it has to be configured as an input GPIO. IGEPv2 platform code sets the smsc911x_cfg->gpio_irq to GPIO 176 but since the mux pin default mode is MODE7 (safe_mode) the driver fails when trying to register the IRQ with the following error message: [ 1.994598] smsc911x: Driver version 2008-10-21 [ 3.704162] irq 272: nobody cared (try booting with the "irqpoll" option) [ 3.711364] [<c001a114>] (unwind_backtrace+0x0/0xf0) from [<c009a0d4>] (__report_bad_irq+0x20/0xbc) [ 3.720916] [<c009a0d4>] (__report_bad_irq+0x20/0xbc) from [<c009a41c>] (note_interrupt+0x1d8/0x238) [ 3.730560] [<c009a41c>] (note_interrupt+0x1d8/0x238) from [<c0098234>] (handle_irq_event_percpu+0xc0/0x260) [ 3.740936] [<c0098234>] (handle_irq_event_percpu+0xc0/0x260) from [<c0098410>] (handle_irq_event+0x3c/0x5c) [ 3.751312] [<c0098410>] (handle_irq_event+0x3c/0x5c) from [<c009abe0>] (handle_level_irq+0xac/0x10c) [ 3.761047] [<c009abe0>] (handle_level_irq+0xac/0x10c) from [<c0097a34>] (generic_handle_irq+0x30/0x48) [ 3.770935] [<c0097a34>] (generic_handle_irq+0x30/0x48) from [<c02a6b74>] (gpio_irq_handler+0x180/0x1d4) [ 3.780944] [<c02a6b74>] (gpio_irq_handler+0x180/0x1d4) from [<c0097a34>] (generic_handle_irq+0x30/0x48) [ 3.790954] [<c0097a34>] (generic_handle_irq+0x30/0x48) from [<c0013e18>] (handle_IRQ+0x4c/0xac) [ 3.800231] [<c0013e18>] (handle_IRQ+0x4c/0xac) from [<c000858c>] (omap3_intc_handle_irq+0x60/0x74) [ 3.809783] [<c000858c>] (omap3_intc_handle_irq+0x60/0x74) from [<c04979e4>] (__irq_svc+0x44/0x60) [ 3.819213] Exception stack(0xee42fde0 to 0xee42fe28) [ 3.824554] fde0: 00000001 00000001 00000000 00000000 60000013 c06cce14 c06cce14 00000110 [ 3.833190] fe00: 00000000 c06ccdf4 60000013 ee41d000 fb058064 ee42fe28 c0089e08 c04976b4 [ 3.841796] fe20: 20000013 ffffffff [ 3.845489] [<c04979e4>] (__irq_svc+0x44/0x60) from [<c04976b4>] (_raw_spin_unlock_irqrestore+0x34/0x44) [ 3.855499] [<c04976b4>] (_raw_spin_unlock_irqrestore+0x34/0x44) from [<c0099744>] (__setup_irq+0x1b8/0x3f0) [ 3.865875] [<c0099744>] (__setup_irq+0x1b8/0x3f0) from [<c0099a34>] (request_threaded_irq+0xb8/0x140) [ 3.875701] [<c0099a34>] (request_threaded_irq+0xb8/0x140) from [<c0487950>] (smsc911x_drv_probe+0x75c/0x11a4) [ 3.886260] [<c0487950>] (smsc911x_drv_probe+0x75c/0x11a4) from [<c02e9bcc>] (platform_drv_probe+0x18/0x1c) [ 3.906707] [<c02e89b8>] (driver_probe_device+0x90/0x210) from [<c02e8bcc>] (__driver_attach+0x94/0x98) [ 3.916625] [<c02e8bcc>] (__driver_attach+0x94/0x98) from [<c02e7298>] (bus_for_each_dev+0x50/0x7c) [ 3.926177] [<c02e7298>] (bus_for_each_dev+0x50/0x7c) from [<c02e81d4>] (bus_add_driver+0x184/0x248) [ 3.935821] [<c02e81d4>] (bus_add_driver+0x184/0x248) from [<c02e909c>] (driver_register+0x78/0x12c) [ 3.945465] [<c02e909c>] (driver_register+0x78/0x12c) from [<c0008648>] (do_one_initcall+0x34/0x178) [ 3.955108] [<c0008648>] (do_one_initcall+0x34/0x178) from [<c066e8f4>] (kernel_init+0xfc/0x1c0) [ 3.964385] [<c066e8f4>] (kernel_init+0xfc/0x1c0) from [<c00140b0>] (kernel_thread_exit+0x0/0x8) [ 3.973632] handlers: [ 3.976043] [<c034e2cc>] smsc911x_irqhandler [ 3.980560] Disabling IRQ #272 Signed-off-by: Javier Martinez Canillas <javier@dowhile0.org> --- arch/arm/mach-omap2/board-igep0020.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-)
