Hello,
This patch series is the 4th version of the new at91 clock implementation
(using common clk framework).
Mike, DT maintainers,
Can you have a look at this series converting the AT91 family to common
clock framework and associated Device Tree description?
Here is the thread on gmane:
http://thread.gmane.org/gmane.linux.ports.arm.kernel/272550
Mike, I think that you already reviewed a previous version of this
series and I guess that we have finalized it.
So gentlemen, It can be good for us if you can give us your "review" or
"acknowledgement" tags...
Thanks, best regards,
Most of the clock provided by the PMC (Power Management Controller) are
implemented :
- main clock (main oscillator)
- pll clocks
- master clock
- programmable clocks
- utmi clock
- peripheral clocks
- system clocks
This implementation is only compatible with device tree definition.
The goal is to define the whole clock tree in the device tree.
Could a dt maintainer take a look at these dt bindinds.
This patch series is based on linus tree (but should apply correctly on
linux-next) and has been tested on sama5d31ek.
Best Regards,
Boris
Changes since v3:
- simplify master clk implementation (drop set_rate/parent support)
- fix bug in set_rate function of pll driver
- fix coding style issues
- define macros and constants where needed
- remove peripheral id macro references
- remove sam9g35 specific handling (sam9g35 = sam9x5)
- rework main clk prepare function to handle automatic rate calculation
Changes since v2:
- fix several bugs in clk implementations
- drop non-dt boards support
- split the series to ease review and tests:
* 1 patch series for new clk implementations (this series)
* 1 patch series to move each at91 SoC to common clk framework (coming soon)
- modify dt-bindings (add atmel,clk- prefix to atmel specific properties)
- add clk macros for dt-bindings
- add pmc framework (helper function to access pmc registers)
- add interrupt support to enable passive wait in clk_prepare functions
Changes since v1:
- fix bugs in pll, programmable and system clock implementations
(wrong bit position).
- add usb clock configuration support (ohci and udc drivers +
clk_lookup for non dt boards)
- rework of the system clock interfaces (no need to define a parent clock,
system clock is a gate with no rate info)
- change system, peripheral and programmable clk dt bindings (1 master node
and multiple child nodes each defining a system/peripheral or prog clock)
- fix bugs in sama5 dt definition
