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

MIPS: AR7: Normalize clk API

2018-06-28T21:28:59+00:00

Coldfire still provides its own variant of the clk API rather than using the generic COMMON_CLK API. This generally works, but it causes some link errors with drivers using the clk_round_rate(), clk_set_rate(), clk_set_parent(), or clk_get_parent() functions when a platform lacks those interfaces. This adds empty stub implementations for each of them, and I don't even try to do something useful here but instead just print a WARN() message to make it obvious what is going on if they ever end up being called. The drivers that call these won't be used on these platforms (otherwise we'd get a link error today), so the added code is harmless bloat and will warn about accidental use.

MIPS: AR7: allow NULL clock for clk_get_rate

2017-09-06T10:35:21+00:00

Make the behaviour of clk_get_rate consistent with common clk's clk_get_rate by accepting NULL clocks as parameter. Some device drivers rely on this, and will cause an OOPS otherwise.

MIPS: Audit and remove any unnecessary uses of module.h

2017-02-14T09:00:25+00:00

Historically a lot of these existed because we did not have a distinction between what was modular code and what was providing support to modules via EXPORT_SYMBOL and friends. That changed when we forked out support for the latter into the export.h file. This means we should be able to reduce the usage of module.h in code that is obj-y Makefile or bool Kconfig. In the case of some code where it is modular, we can extend that to also include files that are building basic support functionality but not related to loading or registering the final module; such files also have no need whatsoever for module.h The advantage in removing such instances is that module.h itself sources about 15 other headers; adding significantly to what we feed cpp, and it can obscure what headers we are effectively using. Since module.h might have been the implicit source for init.h (for __init) and for export.h (for EXPORT_SYMBOL) we consider each instance for the presence of either and replace/add as needed. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. Build coverage of all the mips defconfigs revealed the module.h header was masking a couple of implicit include instances, so we add the appropriate headers there.

MIPS: AR7: Fix loops per jiffies on TNETD7200 devices

2010-12-16T18:10:56+00:00

TNETD7200 run their CPU clock faster than the default CPU clock we assume. In order to have the correct loops per jiffies settings, initialize clocks right before setting mips_hpt_frequency. As a side effect, we can no longer use msleep in clocks.c which requires other parts of the kernel to be initialized, so replace these with mdelay.
