2017-01-26clk: ux500: move AB8500 sysclk over to PRCMU clk driverLinus Walleij
The AB8500 sysclk is just another PRCMU-controlled clock, there is no reason why it should be in the ABx500-controlled part of the clock implementation. Doing this and the corresponding device tree changes makes USB work on the Ux500 again.

2016-07-12ARM: ux500: use CLK_OF_DECLARE()Arnd Bergmann
The ux500 DT support predates the CLK_OF_DECLARE macro and calls directly into the clk driver from platform code. Converting this to CLK_OF_DECLARE makes the code much nicer and similar to how modern platforms do it today. It also removes the last user of cpu_is_u8500_family() etc. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-03-02clk: ux500: Remove CLK_IS_ROOTStephen Boyd
This flag is a no-op now. Remove usage of the flag. Acked-by: Ulf Hansson <ulf.hansson@linaro.org> Cc: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2015-08-24clk/ARM: move Ux500 PRCC bases to the device treeLinus Walleij
The base addresses for the Ux500 PRCC controllers are hardcoded, let's move them to the clock node in the device tree and delete the constants.

2015-07-20clk: ux500: Remove clk.h and clkdev.h includesStephen Boyd
Clock provider drivers generally shouldn't include clk.h because it's the consumer API. Remove the include here because this is a provider driver. Also remove clkdev.h in files that aren't using it.

2015-05-07clk: ux500: ape[ate|trace]clk are scaleableLinus Walleij
The APEATCLK and APETRACECLK are actually scaleable so register them as scaleable clocks. Acked-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

2013-10-18clk: ux500: fix erroneous bit assignmentLinus Walleij
Due to a typo or similar, the peripheral group 2 clock 11 gate was set to bit 1 instead of bit 11. We need to fix this to be able to set the correct enable bit in the device tree: when trying to correct the bit assignment in the device tree, the system would hang.

2013-09-26clk: ux500: Add a 2-cell Device Tree parser for obtaining PRCC clocksLee Jones
PRCC (peripheral and kernel) clocks are specified using a property tuple <&phandle base bit>, where 'base' is the peripheral (1, 2, 3, 5 or 6), and bit is read-in value into that peripheral stipulated by the hardware specification.

Here we're using the old clock initialisation function as a template. It's necessary to remove all of the clk_register_clkdev() calls as they don't make sense when booting with Device Tree.
