For imx27, it needs three clocks to let the controller work, the old code is wrong, and usbmisc has not included clock handling code any more. Without this patch, it will cause below data abort when accessing usbmisc registers. usbcore: registered new interface driver usb-storage Unhandled fault: external abort on non-linefetch (0x008) at 0xf4424600 pgd = c0004000 [f4424600] *pgd=10000452(bad) Internal error: : 8 [#1] PREEMPT ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper Not tainted 4.1.0-next-20150701-dirty #3089 Hardware name: Freescale i.MX27 (Device Tree Support) task: c7832b60 ti: c783e000 task.ti: c783e000 PC is at usbmisc_imx27_init+0x4c/0xbc LR is at usbmisc_imx27_init+0x40/0xbc pc : [<c03cb5c0>] lr : [<c03cb5b4>] psr: 60000093 sp : c783fe08 ip : 00000000 fp : 00000000 r10: c0576434 r9 : 0000009c r8 : c7a773a0 r7 : 01000000 r6 : 60000013 r5 : c7a776f0 r4 : c7a773f0 r3 : f4424600 r2 : 00000000 r1 : 00000001 r0 : 00000001 Flags: nZCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment kernel Control: 0005317f Table: a0004000 DAC: 00000017 Process swapper (pid: 1, stack limit = 0xc783e190) Stack: (0xc783fe08 to 0xc7840000) Signed-off-by: Peter Chen <peter.chen@freescale.com> Reported-by: Fabio Estevam <fabio.estevam@freescale.com> Tested-by: Fabio Estevam <fabio.estevam@freescale.com> Cc: <stable@vger.kernel.org> #v4.1+ Acked-by: Shawn Guo <shawnguo@kernel.org>
