clk: at91: add slow clks driver

2014-05-07T16:27:45+00:00

AT91 slow clk is a clk multiplexer.

In some SoCs (sam9x5, sama5, sam9g45 families) this multiplexer can
choose among 2 sources: an internal RC oscillator circuit and an oscillator
using an external crystal.

In other Socs (sam9260 family) the multiplexer source is hardcoded with
the OSCSEL signal.

clk: at91: rework main clk implementation

2014-05-07T16:27:22+00:00

AT91 main clk is a clk multiplexer and not a simple fixed rate clk as
currently implemented.

In some SoCs (sam9x5, sama5, sam9g45 families) this multiplexer can
choose among 2 sources: an internal RC oscillator circuit and an
oscillator using an external crystal.

In other Socs (sam9260, rm9200 families) the multiplexer source is
hardcoded to the external crystal oscillator.

clk: at91: fix programmable clk irq handling

2014-03-19T22:21:56+00:00

The PCKRDY bit is not set until the system clock is enabled.
This patch moves the management of the ready status in the system clock
driver.

clk: at91: propagate rate change on system clks

2014-03-19T22:21:52+00:00

System clks are just gates, and thus do not provide any rate operations.
Authorize clk rate change to be propagated to system clk parents.

clk: at91: replace prog clk round_rate with determine_rate

2014-03-19T22:21:39+00:00

Implement the determine_rate callback to choose the best parent clk that
fulfills the requested rate.

clk:at91: Fix memory leak in of_at91_clk_master_setup()

2014-02-27T02:00:56+00:00

cppcheck detected following error
[clk-master.c:245]: (error) Memory leak: characteristics

The original code forgot to free characteristics when
irq_of_parse_and_map() failed.

ARM: at91: remove AT91_PROGRAMMABLE_CLOCKS configuration option

2013-12-12T17:57:42+00:00

This AT91 specific Kconfig option removed the code that dealt with
programmable clocks. Each AT91 SoC embeds programmable clocks and
there is little gain to remove this code in case that such a clock
is not used.
If this option is not selected, it causes certain drivers to fail
to build. We simply remove this option instead of adding code just
to build a workaround.
