Subject: [PATCH v6 00/16] ARM: at91: move to common clk framework
Hello,
This patch series is the 5th version of the at91 clk implementations
using the 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
Actually some clk drivers are missing (slow clk, main clk and processor
clk), and some drivers only implement a subset of the hardware capabilities
(master clk rate change is missing).
But this series implements all the already available clks, and I will hopefully
add missing features in a near future.
This implementation is only compatible with device tree definition.
The goal is to define the whole clock tree using the device tree.
Just a note to let you know these bindings are currently unstable and might
change in the future.
Best Regards,
Boris
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
