clk: at91: fix num_parents test in at91sam9260 slow clk implementation

2014-09-02T21:44:41+00:00

The slow clk block provided by at91sam9260 and derived SoCs should always
have 2 parents.

clk: at91: main: warn when the main crystal frequency is not set

2014-07-02T16:00:52+00:00

When the main crystal frequency is not set, the main clock is approximated using
the MAINF value in the CKGR_MCFR register. Warn the user in that case.

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.
