I've rebased this series on the next-20170413 for sanity sake, and realized there doesn't appear to be a way to select CONFIG_IMX_GPCV2. I forced it using 'default y' and configured with imx_v6_v7_defconfig. Now my board is booting. Before this series is applied, it may be good to have CONFIG_IMX_GPCV2 selected specifically for iMX7 platform, otherwise there will be boot regressions. I'd encounter a backtrace with next-20170413 + imx_v6_v7_defconfig + CONFIG_IMX_GPCV2=y Backtrace: [<c010c364>] (dump_backtrace) from [<c010c610>] (show_stack+0x18/0x1c) r7:00000000 r6:600000d3 r5:00000000 r4:c0e273dc [<c010c5f8>] (show_stack) from [<c04070a4>] (dump_stack+0xb4/0xe8) [<c0406ff0>] (dump_stack) from [<c0169e04>] (register_lock_class+0x208/0x5ec) r9:ef00d010 r8:ef00d010 r7:c1606448 r6:00000000 r5:00000000 r4:ffffe000 [<c0169bfc>] (register_lock_class) from [<c016da48>] (__lock_acquire+0x7c/0x18d0) r10:c0e0af40 r9:ef00d010 r8:c0e274cc r7:00000001 r6:600000d3 r5:c1606448 r4:ffffe000 [<c016d9cc>] (__lock_acquire) from [<c016fa4c>] (lock_acquire+0x70/0x90) r10:00000000 r9:ef007e38 r8:00000001 r7:00000001 r6:600000d3 r5:00000000 r4:ffffe000 [<c016f9dc>] (lock_acquire) from [<c09accc8>] (_raw_spin_lock+0x30/0x40) r8:600000d3 r7:ef007e10 r6:00000001 r5:ef007e10 r4:ef00d000 [<c09acc98>] (_raw_spin_lock) from [<c04403a4>] (imx_gpcv2_irq_unmask+0x1c/0x5c) r4:ef00d000 [<c0440388>] (imx_gpcv2_irq_unmask) from [<c017e838>] (irq_enable+0x38/0x4c) r5:00000000 r4:ef007e00 [<c017e800>] (irq_enable) from [<c017e8d0>] (irq_startup+0x84/0x88) r5:00000000 r4:ef007e00 [<c017e84c>] (irq_startup) from [<c017cd7c>] (__setup_irq+0x538/0x5f4) r7:ef007e60 r6:00000015 r5:ef007e00 r4:ef007d00 [<c017c844>] (__setup_irq) from [<c017ce98>] (setup_irq+0x60/0xd0) r10:c0d5fa48 r9:efffcbc0 r8:ef007d00 r7:00000015 r6:ef007e10 r5:00000000 r4:ef007e00 [<c017ce38>] (setup_irq) from [<c0d4dfdc>] (_mxc_timer_init+0x1f8/0x248) r9:efffcbc0 r8:00000003 r7:016e3600 r6:c0c69bbc r5:ef007c40 r4:ef007c00 [<c0d4dde4>] (_mxc_timer_init) from [<c0d4e0dc>] (mxc_timer_init_dt+0xb0/0xf8) r7:00000000 r6:c1669e48 r5:ef7ebf7c r4:ef007c00 [<c0d4e02c>] (mxc_timer_init_dt) from [<c0d4e168>] (imx6dl_timer_init_dt+0x14/0x18) r9:efffcbc0 r8:c0e7b000 r7:c0c695c0 r6:c0d6fe18 r5:00000001 r4:ef7ebf7c [<c0d4e154>] (imx6dl_timer_init_dt) from [<c0d4d158>] (clocksource_probe+0x54/0xb0) [<c0d4d104>] (clocksource_probe) from [<c0d04a2c>] (time_init+0x30/0x38) r7:c0e07900 r6:c0e7b000 r5:ffffffff r4:00000000 [<c0d049fc>] (time_init) from [<c0d00bc8>] (start_kernel+0x220/0x3a0) [<c0d009a8>] (start_kernel) from [<8000807c>] (0x8000807c) r10:00000000 r9:410fc075 r8:8000406a r7:c0e0c958 r6:c0d5fa44 r5:c0e07918 r4:c0e7b294 Cheers, Tyler -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
