2018-12-15clk: Use of_node_name_eq for node name comparisonsRob Herring1-5/+5
Convert string compares of DT node names to use of_node_name_eq helper instead. This removes direct access to the node name pointer. For instances using of_node_cmp, this has the side effect of now using case sensitive comparisons. This should not matter for any FDT based system which all of these are.

2017-01-27clk: ux500: move AB8500 sysclk over to PRCMU clk driverLinus Walleij1-0/+3
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 Bergmann1-14/+2
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>

2015-08-25clk/ARM: move Ux500 PRCC bases to the device treeLinus Walleij1-71/+92
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 Boyd1-2/+0
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.

2013-10-18clk: ux500: fix erroneous bit assignmentLinus Walleij1-1/+1
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.

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.
