clk: at91: fix check of clk_register() returned value

2016-06-08T01:18:50Z

commit cb0ceaf77d93964a0d00477c79f4499123f6159c upstream. The clk_register() function returns a valid pointer to struct clk or ERR_PTR() error code, this makes a check for returned NULL value useless and may lead to oops on error path.

clk: at91: Revert "keep slow clk enabled to prevent system hang"

2015-11-20T18:53:12Z

Commit dca1a4b5ff6e ("clk: at91: keep slow clk enabled to prevent system hang") added a workaround for the slow clock as it is not properly handled by its users. Now that the slow clock is taken properly by the drivers, this workaround is not necessary anymore, revert it.

clk: at91: add generated clock driver

2015-10-01T19:48:11Z

Add a new type of clocks that can be provided to a peripheral. In addition to the peripheral clock, this new clock that can use several input clocks as parents can generate divided rates. This would allow a peripheral to have finer grained clocks for generating a baud rate, clocking an asynchronous part or having more options in frequency.

clk: at91: add PMC sama5d2 support

Add support for the new sama5d2 SoC and adapt capabilities. Signed-off-by: Nicolas Ferre Signed-off-by: Boris Brezillon Signed-off-by: Stephen Boyd

clk: at91: modify PMC peripheral clock to deal with newer register layout

2015-10-01T19:39:43Z

As some more information is added to the PCR register, we'd better use a copy of its content and modify just the peripheral-related bits. Implement a read-modify-write for the enable() and disable() callbacks. Signed-off-by: Nicolas Ferre Signed-off-by: Boris Brezillon Signed-off-by: Stephen Boyd

clk: at91: cleanup PMC header file for PCR register fields

2015-10-01T19:39:41Z

Add _MASK and _OFFSET values and cleanup register fields layout. Signed-off-by: Nicolas Ferre Signed-off-by: Boris Brezillon Signed-off-by: Stephen Boyd

clk: at91: system: don't try to free_irq when there is no IRQ

2015-09-16T22:22:22Z

In the error path of at91_clk_register_system(), sys->irq is freed unconditionally but it may not exist or be request at all. Signed-off-by: Alexandre Belloni Acked-by: Boris Brezillon Signed-off-by: Stephen Boyd

clk: at91: utmi: use pmc_read when the at91_pmc is available

2015-09-16T22:22:20Z

at91_pmc_read is a workaround to allow external drivers to acces some registers of the PMC. There is no need for it in clk-utmi.c as we aready have a pointer to the struct at91_pmc. Signed-off-by: Alexandre Belloni Acked-by: Boris Brezillon Signed-off-by: Stephen Boyd

clk: at91: Convert to clk_hw based provider APIs

2015-08-24T23:48:47Z

We're removing struct clk from the clk provider API, so switch this code to using the clk_hw based provider APIs. Acked-by: Boris Brezillon Signed-off-by: Stephen Boyd
