remove ioremap_nocache and devm_ioremap_nocache

2020-01-06T08:45:59+00:00

ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig Acked-by: Arnd Bergmann

cpufreq: Add and use cpufreq_for_each_{valid_,}entry_idx()

2018-02-08T09:21:39+00:00

Pointer subtraction is slow and tedious. Therefore, replace all instances where cpufreq_for_each_{valid_,}entry loops contained such substractions with an iteration macro providing an index to the frequency_table entry.

drivers: sh: clk: Avoid crashes when passing NULL clocks

2015-11-24T02:49:18+00:00

Several clock API functions handle NULL clocks when the Common Clock Framework is used, while their legacy SH counterparts don't, and would just crash when a NULL clock is passed. Add NULL checks to clk_get_rate(), clk_set_rate(), clk_get_parent(), and clk_round_rate(), to avoid different behavior in drivers shared between legacy and CCF-based platforms.

drivers: sh: clk: Remove obsolete and unused clk_round_parent()

2015-11-24T02:48:35+00:00

clk_round_parent() was only ever used by AP4EVB, until commit b24bd7e97b3784af ("ARM: shmobile: Remove AP4EVB board support"). The Common Clock Framework does not provide clk_round_parent(), hence remove it. Signed-off-by: Geert Uytterhoeven Signed-off-by: Simon Horman

sh: clk: Use cpufreq_for_each_valid_entry macro for iteration

2014-04-29T22:07:00+00:00

The cpufreq core now supports the cpufreq_for_each_valid_entry macro helper for iteration over the cpufreq_frequency_table, so use it. It should have no functional changes. Signed-off-by: Stratos Karafotis Acked-by: Viresh Kumar Signed-off-by: Rafael J. Wysocki

cpufreq: rename index as driver_data in cpufreq_frequency_table

2013-06-04T12:25:59+00:00

The "index" field of struct cpufreq_frequency_table was never an index and isn't used at all by the cpufreq core. It only is useful for cpufreq drivers for their internal purposes. Many people nowadays blindly set it in ascending order with the assumption that the core will use it, which is a mistake. Rename it to "driver_data" as that's what its purpose is. All of its users are updated accordingly. [rjw: Changelog] Signed-off-by: Viresh Kumar Acked-by: Simon Horman Signed-off-by: Rafael J. Wysocki

sh: extend clock struct with mapped_reg member

2011-12-09T09:01:05+00:00

Add a "mapped_reg" member to struct clk and use that to keep the ioremapped register based on enable_reg. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: clkfwk: Kill off remaining debugfs cruft.

2011-11-11T07:11:41+00:00

Now that all of the named string association with clocks has been migrated to clkdev lookups there's no meaningful named topology that can be constructed for a debugfs tree view. Get rid of the left over bits, and shrink struct clk a bit in the process. Signed-off-by: Paul Mundt

sh: clkfwk: add clk_rate_mult_range_round()

2011-11-04T15:49:27+00:00

This provides a clk_rate_mult_range_round() helper for use by some of the CPG PLL ranged multipliers, following the same approach as used by the div ranges. Signed-off-by: Kuninori Morimoto Signed-off-by: Paul Mundt
