Subject: [PATCH v5 00/17] ARM: at91: move to common clk framework
Date: Tue, 12 Nov 2013 21:51:52 +0100 [thread overview]
Message-ID: <1384289513-3068-1-git-send-email-b.brezillon@overkiz.com> (raw)
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.
BTW, could a dt maintainer take a look at these dt bindinds ?
Just a note to let you know these bindings are currently unstable and might
change in the future.
Mike, I know you already acked the previous version, but I slighty changed
the dt bindings, according to some feedbacks I got during ELCE.
Could you take a look at this new version (at least the new dt bindings),
and add your acked-by if you agree with these changes ?
Best Regards,
Boris
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
