Hi,
This patch set is a cleanup that properly separate drivers needing to access the
PMC (PM and USB) from the clock driver by exposing the PMC as a syscon.
This also allows to implement a fix for preempt-rt. Currently, at91 platform are
crashing when using preempt-rt because the irq handler are transformed in
threaded irq handler but at the time the pmc registers its clocks, it is not
possible to creat threads, leading to a NULL pointer dereference in the kernel.
The new infrastructure uses polling until it is late enough to register threaded
irqs.

Alexandre Belloni (13):
clk: at91: utmi: use pmc_read when the at91_pmc is available
clk: at91: system: don't try to free_irq when there is no IRQ
ARM: at91/dt: use syscon for PMC
clk: at91: clk-main: factorize irq handling
clk: at91: make IRQ optional and register them later
clk: at91: pmc: merge at91_pmc_init in atmel_pmc_probe
clk: at91: pmc: move pmc structures to C file
ARM: at91: pm: simply call at91_pm_init
ARM: at91: pm: find and remap the pmc
ARM: at91: pm: move idle functions to pm.c
ARM: at91: remove useless includes and function prototypes
usb: gadget: atmel: access the PMC using regmap
clk: at91: pmc: drop at91_pmc_base
Boris Brezillon (3):
clk: at91: make use of syscon to share PMC registers in several
drivers
clk: at91: make use of syscon/regmap internally
clk: at91: only enable available IRQs
