Merge tag 'at91-fixes' of git://github.com/at91linux/linux-at91 into next/fixes-non-critical
From Nicolas Ferre:
Several fixes for:
- external irq on non-DT boards
- cpuidle code in some circumstances
- PMC code in relation with PLLB/PLL_UTMI/USB:
mainly for SAMA5D3 and AT91SAM9N12
* tag 'at91-fixes' of git://github.com/at91linux/linux-at91:
ARM: at91/PMC: use at91_usb_rate() for UTMI PLL
ARM: at91/PMC: fix at91sam9n12 USB FS init
ARM: at91/PMC: at91sam9n12 family has a PLLB
ARM: at91/PMC: sama5d3 family doesn't have a PLLB
ARM: at91: cpuidle: Fix target_residency
ARM: at91: fix at91_extern_irq usage for non-dt boards
