This series includes updates for the bcm281xx clock code for 3.15.
I had held off posting this until the code on which this is based
was queued for 3.14, and it now has been:
clk: bcm281xx: don't disable unused peripheral clocks
clk: bcm281xx: add initial clock framework support
ARM: dts: bcm281xx: define real clocks
The patches in this series are available here:
I've grouped them, and offer a little explanation of each of the
Note: The final (DT) patch *must* be committed last.
The first version of this series had a patch from the middle of the
series that shouldn't have been there, and it has been removed in
this version (that patch affected mach-bcm, not clk). I also split
the final patch into two, with the second one isolating the change
to a device tree file.
Alex Elder (12):
clk: bcm281xx: warn if ccu_wait_bit() fails
clk: bcm281xx: use init_data.name for clock name
clk: bcm281xx: change some symbol names
Three small code improvements.
clk: bcm281xx: initialize CCU structures statically
clk: bcm281xx: define CCU clock data statically
Rearrange the way CCUs and the clocks they provide are
defined, so that they're defined statically to the extent
possible rather than allocating and initializing things at
clk: bcm281xx: add clock policy support
clk: bcm281xx: add clock hysteresis support
clk: bcm281xx: add an initialized flag
clk: bcm281xx: implement prerequisite clocks
clk: bcm281xx: add bus clock support
clk: bcm281xx: define a bus clock
Add a few new features, ultimately for the purpose of adding
support for another type of Kona clock. Currently only
peripheral clocks are supported; this adds the ability to
define and control bus clocks. In addition, support is
added for clocks to identify a prerequisite clock; a clock
won't be initialized until after its prerequisite has been.
ARM: dts: add bus clock bsc3_apb for bcm281xx
Add the new bus clock to the device tree.
