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...
I guess you want to take this through your tree? If so please add: Acked-by: Mike Turquette <redacted> Regards, Mike
Thanks, best regards,quoted
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 Boris BREZILLON (17): ARM: at91: move at91_pmc.h to include/linux/clk/at91_pmc.h ARM: at91: add Kconfig options for common clk support clk: at91: add PMC base support clk: at91: add PMC macro file for dt definitions clk: at91: add PMC main clock clk: at91: add PMC pll clocks clk: at91: add PMC master clock clk: at91: add PMC system clocks clk: at91: add PMC peripheral clocks clk: at91: add peripheral clk macros for peripheral clk dt bindings clk: at91: add PMC programmable clocks clk: at91: add PMC utmi clock clk: at91: add PMC usb clock clk: at91: add PMC smd clock clk: at91: add PMC clk device tree binding doc.
