Mike, Boris,
I will take the series in the at91 git tree that will go through arm-soc.
This way, I can synchronize with the other series cooked by Boris which
actually implements the CCF for sama5d3 SoCs.
Mike, I keep you in the CC list of my upcoming pull-request to Olof,
Kevin and Arnd.
Thanks, bye,

>> Changes since v5:
>> - remove peripheral divisors macros from dt binding include file
>> - remove file path from comment blocks
>> - replace pll and utmi disable function by unprepare function to
>> avoid issue when disabling and reenabling a clk
>> - fix programmable clk interrupt retrieval
>> - fix OF_CLK_DECLARE names (xxx_clk_main -> xxx_clk_pmc)
>> - add missing comma in at91rm9200 main clk dt declaration
>> - fix num_parents check in smd clk driver
>>
>> Changes since v4:
>> - rework dt bindings:
>> * replace "atmel,clk-id" property by the standard "reg" property
>> * reference system, peripheral and programmable clks using the direct
>> clk node instead of the parent node plus a clk id
>> - provide a new helper function (of_at91_get_clk_range) to retrieve a clk
>> range from the device tree
>>
>> 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
>>
