macintosh: Use of_property_present() for testing DT property presence

2023-03-30T12:36:35Z

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

macintosh: Prepare cleanup of powerpc's asm/prom.h

2022-05-11T13:06:39Z

powerpc's asm/prom.h brings some headers that it doesn't need itself. In order to clean it up, first add missing headers in users of asm/prom.h Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/04961364547fe4556e30cb302b0e20a939b83426.1648833027.git.christophe.leroy@csgroup.eu

rackmeter: Use vtime aware kcpustat accessor

2019-11-21T06:59:00Z

Now that we have a vtime safe kcpustat accessor, use it to fetch CPUTIME_NICE and fix frozen kcpustat values on nohz_full CPUs.

treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 246

2019-06-19T15:09:08Z

Based on 1 normalized pattern(s): released under the term of the gnu gpl v2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 16 file(s).

macintosh: Use of_node_name_{eq, prefix} for node name comparisons

2018-12-22T10:29:56Z

Convert string compares of DT node names to use of_node_name_{eq,prefix} helpers instead. This removes direct access to the node name pointer. This changes a single case insensitive node name comparison to case sensitive for "ata4". This is the only instance of a case insensitive comparison for all the open coded node name comparisons on powerpc. Searching the commit history, there doesn't appear to be any reason for it to be case insensitive. A couple of open coded iterating thru the child node names are converted to use for_each_child_of_node() instead. Signed-off-by: Rob Herring Signed-off-by: Michael Ellerman

drivers: macintosh: rack-meter: really fix bogus memsets

2018-03-30T13:10:35Z

We should zero an array using sizeof instead of number of elements. Fixes the following compiler (GCC 7.3.0) warnings: drivers/macintosh/rack-meter.c: In function 'rackmeter_do_pause': drivers/macintosh/rack-meter.c:157:2: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size] drivers/macintosh/rack-meter.c:158:2: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size] Fixes: 4f7bef7a9f69 ("drivers: macintosh: rack-meter: fix bogus memsets") Reported-by: Stephen Rothwell Signed-off-by: Aaro Koskinen Signed-off-by: Michael Ellerman

powerpc: Use sizeof(*foo) rather than sizeof(struct foo)

2018-03-20T05:47:53Z

It's slightly less error prone to use sizeof(*foo) rather than specifying the type. Signed-off-by: Markus Elfring [mpe: Consolidate into one patch, rewrite change log] Signed-off-by: Michael Ellerman

macintosh: Convert to using %pOF instead of full_name

2017-09-01T06:42:52Z

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node. Signed-off-by: Rob Herring [mpe: Also convert the two cases inside #if 0] Signed-off-by: Michael Ellerman

macintosh/rack-meter: Make of_device_ids const

of_device_ids are not supposed to change at runtime. All functions working with of_device_ids provided by work with const of_device_ids. So mark the non-const structs as const.
