I don't see the WARNING when booting mpc8379rdb with SPI enabled (though I do see the "master is unqueued" message). I don't have easy access to an mpc8313erdb to test on. -Scott ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev

spi, spi_fsl-spi.c not working?
Hello all, I just tried a mpc83xx based board (similiar to the mpc8313erdb) with linux v3.16-rc4 using the drivers/spi/spi-fsl-spi.c driver. DT nodes for spi are the same as in arch/powerpc/boot/dts/mpc8313erdb.dts: spi@7000 { cell-index = <0>; compatible = "fsl,spi"; reg = <0x7000 0x1000>; interrupts = <16 0x8>; interrupt-parent = <&ipic>; mode = "cpu"; }; Bootlog shows: [1.341411] fsl_spi f0007000.spi: master is unqueued, this is deprecated [1.554405] [ cut here ] [1.559080] WARNING: at c023a958 [verbose debug info unavailable] [1.565208] Modules linked in: [1.568305] CPU: 0 PID: 1 Comm: swapper Not tainted 3.16.0-rc4-ids720-patch1-01642-g69ef753 #20 [1.577059] task: c782c000 ti: c781a000 task.ti: c781a000 [1.582493] NIP: c023a958 LR: c0238bfc CTR: c027884c [1.587491] REGS: c781bb80 TRAP: 0700 Not tainted (3.16.0-rc4-ids720-patch1-01642-g69ef753) [1.596149] MSR: 00029032 CR: 22002044 XER: [1.602851] GPR00: c0238bfc c781bc30 c782c000 c051421c c6c62a00 c6c62b06 c03e392c 0002 GPR08: c03de53c 0001 c6c62ab8 1032 82002042 c0004158 GPR16: c0495c54 c0495cbc c0495cc8 c0495cd4 GPR24: c050c6a4 c051421c c0544aa8 c054 c6c62a00 [1.632952] NIP [c023a958] driver_probe_device+0x58/0x230 [1.638397] LR [c0238bfc] bus_for_each_drv+0x50/0xac [1.643390] Call Trace: [1.645865] [c781bc30] [c023abf0] __device_attach+0x0/0x70 (unreliable) [1.652539] [c781bc50] [c0238bfc] bus_for_each_drv+0x50/0xac [1.658247] [c781bc80] [c023a8bc] device_attach+0xb4/0xd8 [1.663693] [c781bca0] [c0239dd4] bus_probe_device+0xa0/0xc4 [1.669400] [c781bcc0] [c0237d68] device_add+0x384/0x520 [1.674762] [c781bd00] [c0279298] spi_add_device+0xb0/0x170 [1.680383] [c781bd20] [c027aac4] spi_register_master+0x500/0x75c [1.686530] [c781bd70] [c027e138] of_fsl_spi_probe+0x494/0x594 [1.692413] [c781bdd0] [c023c1ac] platform_drv_probe+0x28/0x68 [1.698297] [c781bde0] [c023a98c] driver_probe_device+0x8c/0x230 [1.704353] [c781be00] [c023abec] __driver_attach+0xbc/0xc0 [1.709972] [c781be20] [c0238cb4] bus_for_each_dev+0x5c/0xa8 [1.715681] [c781be50] [c023a038] bus_add_driver+0xf4/0x1e4 [1.721300] [c781be70] [c023b394] driver_register+0x88/0x130 [1.727013] [c781be80] [c0003ad0] do_one_initcall+0x8c/0x210 [1.732732] [c781bef0] [c04d30ac] kernel_init_freeable+0x114/0x1c0 [1.738962] [c781bf30] [c0004170] kernel_init+0x18/0x108 [1.744331] [c781bf40] [c000e830] ret_from_kernel_thread+0x5c/0x64 [1.750549] Instruction dump: Did someone detected such a problem with this driver?
