treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 194

2019-05-30T18:29:22+00:00

Based on 1 normalized pattern(s): license terms gnu general public license gpl version 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 161 file(s).

clk: ux500: add range to usleep_range

2019-04-11T18:47:50+00:00

Providing a range for usleep_range() allows the hrtimer subsystem to coalesce timers - the delay is runtime configurable so a factor 2 is taken to provide the range. With the expected range for enable_delay_us being milliseconds, the range should lie in the 250us range which is sufficient for hrtimer optimization.

clk: ux500: Improve sizeof() usage

2017-11-14T01:42:25+00:00

Replace the specification of data structures by pointer dereferences as the parameter for the operator "sizeof" to make the corresponding size determination a bit safer according to the Linux coding style convention. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Acked-by: Ulf Hansson Signed-off-by: Stephen Boyd

clk: ux500: Delete error messages for failed memory allocations

Omit extra messages for a memory allocation failure in these functions. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Acked-by: Ulf Hansson Signed-off-by: Stephen Boyd

clk: ux500: sysctrl: constify clk_ops.

2017-08-31T05:27:23+00:00

clk_ops are not supposed to change at runtime. All functions working with clk_ops provided by work with const clk_ops. So mark the non-const clk_ops as const. Here, Function "clk_reg_sysctrl" is used to initialized clk_init_data. clk_init_data is working with const clk_ops. So make clk_reg_sysctrl non-const clk_ops argument as const.

clk: Convert __clk_get_name(hw->clk) to clk_hw_get_name(hw)

2015-08-24T23:49:12+00:00

Use the provider based method to get a clock's name so that we can get rid of the clk member in struct clk_hw one day.

clk: ux500: clk-sysctrl: handle clocks with no parents

2013-05-29T18:52:18+00:00

Fix clk_reg_sysctrl() to set main clock registers of new struct clk_sysctrl even if the registered clock has no parents. This fixes an issue where "ulpclk" was registered with all clk->reg_* fields uninitialized, causing a -EINVAL error from clk_prepare().

clk: ux500: Add support for sysctrl clocks

2013-04-10T18:27:56+00:00

The abx500 sysctrl clocks are using the ab8500 sysctrl driver to modify the clock hardware. Sysctrl clocks are represented by a ab8500 sysctrl register and with a corresponding bitmask. The sysctrl clocks are slow path clocks, which means clk_prepare and clk_unprepare will be used to gate|ungate these clocks. Signed-off-by: Ulf Hansson Signed-off-by: Mike Turquette
