clk: at91: Add sama5d2 suspend/resume

2017-06-30T01:47:35+00:00

On sama5d2, VDD core maybe be cut while in suspend. This means registers
will be lost. Ensure they are saved and restored properly.

clk: at91: fix clk-generated parenting

2017-06-01T07:47:50+00:00

clk_generated_startup is called after clk_hw_register. So the first call to
get_parent will not have the correct value (i.e. 0) and because this is
cached, it may never be updated.

clk: at91: Use kcalloc() in of_at91_clk_pll_get_characteristics()

2017-04-22T02:20:34+00:00

Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus use the corresponding function "kcalloc".

This issue was detected by using the Coccinelle software.

clk: at91: Fix a return value in case of error

2016-10-20T23:37:56+00:00

If 'clk_hw_register()' fails, it is likely that we expect to return an
error instead of a valid pointer (which would mean success).

clk: at91: sckc: optimize boot time

2016-09-21T00:03:04+00:00

Assume that if the oscillator is enabled (OSC32EN bit is present), the
delay has already elapsed as the bootloader probably waited for the
oscillator to settle. This could waste up to 1.2s.

clk: at91: Add sama5d4 sckc support

2016-09-21T00:02:58+00:00

Starting with sama5d4, the crystal oscillator is always enabled at startup
and the SCKC doesn't have an OSC32EN bit anymore.

Add support for that new controller.

clk: at91: move slow clock controller clocks to sckc.c

2016-09-21T00:02:38+00:00

Move all clocks related to the slow clock controller to sckc.c. This avoids
extern definitions and allows to remove sckc.h

clk: at91: Migrate to clk_hw based registration and OF APIs

2016-09-15T00:40:31+00:00

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers in this driver, allowing us to
move closer to a clear split of consumer and provider clk APIs.
