If you first change the tidss to use the new connector model, and only afterwards fix the bridges we use, then there's a time when the displays won't work. Also, with J7 EVM and DP, when I unload the modules I see: [ 43.238895] irq 31: nobody cared (try booting with the "irqpoll" option) [ 43.245591] CPU: 0 PID: 349 Comm: irq/31-mhdp8546 Not tainted 5.9.0-rc5-00605-g08a291316f86 #4 [ 43.254186] Hardware name: Texas Instruments K3 J721E SoC (DT) [ 43.260006] Call trace: [ 43.262453] dump_backtrace+0x0/0x1d8 [ 43.266107] show_stack+0x18/0x28 [ 43.269416] dump_stack+0xe0/0x14c [ 43.272810] __report_bad_irq+0x4c/0xdc [ 43.276637] note_interrupt+0x2cc/0x388 [ 43.280465] handle_irq_event_percpu+0x88/0x90 [ 43.284898] handle_irq_event+0x48/0xf8 [ 43.288725] handle_fasteoi_irq+0xcc/0x180 [ 43.292811] generic_handle_irq+0x30/0x48 [ 43.296811] __handle_domain_irq+0x94/0x108 [ 43.300986] gic_handle_irq+0x60/0x158 [ 43.304726] el1_irq+0xbc/0x180 [ 43.307862] _raw_spin_unlock_irq+0x48/0x90 [ 43.312035] irq_finalize_oneshot.part.0+0x68/0x108 [ 43.316903] irq_thread_fn+0x60/0xa0 [ 43.320469] irq_thread+0x1b8/0x248 [ 43.323949] kthread+0x128/0x160 [ 43.327169] ret_from_fork+0x10/0x34 [ 43.330735] handlers: [ 43.333020] [<000000005367c4f9>] irq_default_primary_handler threaded [<000000007e02b601>] cdns_mhdp_irq_handler [cdns_mhdp8546] [ 43.344607] Disabling IRQ #31 Tomi -- Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
