Hello,
This patch series is the 3rd version of the new at91 clock implementation
(using common clk framework).
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.
Please feel free to comment the dt bindinds.
This patch series is based on linux-next and has been tested on sama5d31ek
board using device tree. It compiles for other SoCs and both with and
but it has not been tested (Richard, I did not add your Tested-by because
a lot of things have changed since v2).
BTW could other people test it on other boards (I only have a kizbox and
a sama5d31ek dev kit).
Best Regards,
Boris
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
