The clk_disable() in the common clock framework (drivers/clk/clk.c)
returns immediately if the given clk is NULL or an error pointer.
It allows drivers to call clk_disable() (and clk_disable_unprepare())
with a clock that might be NULL or an error pointer as long as the
drivers are only used along
Hi Stephen,
No value for this patch, or just you missed this?

Hi Mike, Stephen,
as discusses previously, here is round 1 of rockchip clock changes for 4.5.
This already includes the clock-id branch shared with the armsoc-

Thanks

The three different irq handlers are doing the same thing, factorize their
code in a generic irq handler.

The AT91 clock drivers make use of IRQs to avoid polling when waiting for
some clocks to be enabled. Unfortunately, this leads to a crash when those
IRQs are threaded (which happens when using preempt-rt) because they are
registered before thread creation is possible.
Use polling on those clocks u

Use the regmap coming from syscon to access the registers instead of using
pmc_read/pmc_write. This allows to avoid passing the at91_pmc structure to
the child nodes of the PMC.
The final benefit is to have each clock register itself instead of having
to iterate over the ch

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

The PMC block is providing several functionnalities:
- system clk management
- cpuidle
- platform suspend
Replace the void __iomem *regs field by a regmap (retrieved using syscon)
so that we can later share the regmap across several drivers without
exporting a new specif
