clk: iproc: fix bit manipulation arithmetic

2015-07-02T16:51:09+00:00

A 32-bit variable should be type casted to 64-bit before arithmetic
operation and assigning it to a 64-bit variable

clk: iproc: fix memory leak from clock name

2015-07-02T16:50:26+00:00

of_property_read_string_index takes array of pointers and assign them to
strings read from device tree property. No additional memory allocation
is needed prior to calling of_property_read_string_index. In fact, since
the array of pointers will be re-assigned to other strings, any memory
that it points to prior to calling of_property_read_string_index will be
leaked

clk: cygnus: add clock support for Broadcom Cygnus

2015-06-18T19:36:39+00:00

The Broadcom Cygnus SoC is architected under the iProc architecture. It
has the following PLLs: ARMPLL, GENPLL, LCPLL0, MIPIPLL, all dervied
from an onboard crystal. Cygnus also has various ASIU clocks that are
derived directly from the onboard crystal.

clk: iproc: add initial common clock support

2015-06-18T19:36:38+00:00

This adds basic and generic support for various iProc PLLs and clocks
including the ARMPLL, GENPLL, LCPLL, MIPIPLL, and ASIU clocks.

SoCs under the iProc architecture can define their specific register
offsets and clock parameters for their PLL and clock controllers. These
parameters can be passed as arugments into the generic iProc PLL and
clock setup functions

clk: bcm/kona: Remove ccu_list

2015-05-15T00:11:20+00:00

This list doesn't look to be used. Let's remove it and any
associated code that would be manipulating this list. This also
silences this error:

Now that the kernel provides DIV_ROUND_CLOSEST_ULL(), drop the internal
implementation and use the kernel one.

clk: Add rate constraints to clocks

2015-02-02T22:23:42+00:00

Adds a way for clock consumers to set maximum and minimum rates. This
can be used for thermal drivers to set minimum rates, or by misc.
drivers to set maximum rates to assure a minimum performance level.

Changes the signature of the determine_rate callback by adding the
parameters min_rate and max_rate.

clk: bcm/kona: implement determine_rate()

2014-05-28T00:34:32+00:00

Implement the clk->determine_rate method for Broadcom Kona peripheral
clocks.  This allows a peripheral clock to be re-parented in order to
satisfy a rate change request.  This takes the place of the previous
kona_peri_clk_round_rate() functionality, though that function remains
because it is used by the new one.

The parent clock that allows the peripheral clock to produce a rate
closest to the one requested is the one selected, though the current
parent is used by default.
