Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas. That ensures only documented properties are present. Add unevaluatedProperties or additionalProperties as appropriate, and then add any missing properties flagged by the addition. Acked-by:

There's a bunch of bindings for (mostly l2) cache controllers scattered to the four winds, move them to a common directory. I renamed the freescale l2cache.txt file, as while that might make sense when the parent dir is fsl, it's confusing after the move. The two Marvell bindings have had a "marvell," prefix added to match their compatibles. Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

unittest_gpio_remove() is only called after unittest_gpio_probe() completed successfully. In this case driver data was set to a non-NULL value and so platform_get_drvdata() never returns NULL. Also note that the compiler might optimize away this check anyhow as devptr was already dereferenced for the dev_dbg call above. Drop this if block. Signed-off-by:

The driver core already unsets driver data after .remove() completes. So there is no reason to do this explicitly in the driver itself. Signed-off-by:

Convert Freescale CAAM/SEC4 binding to DT schema format. The 'fsl,sec-v4.0' and 'fsl,sec-v4.0-mon' parts are independent, so split them into separate schema files. Add a bunch of missing compatibles for v5.0, v5.4, etc. Drop unused 'ranges', '#address-cells', and '#size-cells' from fsl,sec-v4.0-mon nodes. There's one DTB warning for LS1012a which has a 2nd 'reg' entry for 'fsl,sec-v4.0-rtic'. Leaving that as there is no clue as to what it is for. Reviewed-by:

Enable yamllint to check the preferred commenting style of requiring a space after a comment character '#'. Fix the cases in the tree which have a warning with this enabled. Most cases just need a space after the '#'. A couple of cases with comments which were not intended to be comments are revealed. Those were in ti,sa2ul.yaml, ti,cal.yaml, and brcm,bcmgenet.yaml.

SPI and I2C bus node names are expected to be "spi" or "i2c", respectively, with nothing else, a unit-address, or a '-N' index. A pattern of 'spi0' or 'i2c0' or similar has crept in. Fix all these cases. Mostly scripted with the following commands: git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/' git grep -l '\sspi[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/spi[0-9] {/spi {/' With this, a few errors in examples were exposed and fixed.

Commit aa47a7c2 ("lib/cpumask: deprecate nr_cpumask_bits") resulted in the cpumask operations potentially becoming hugely less efficient, because suddenly the cpumask was always considered to be variable-sized. The optimization was then later added back in a limited form by commit 6f9c07be ("lib/cpumask: add FORCE_NR_CPUS config option"), but that FORCE_NR_CPUS option is not useful in a generic kernel and more of a special case for embedded situations with fixed hardware. Instead, just re-introduce the optimization, with some changes. Instead of depending on CPUMASK_OFFSTACK being false, and then always using the full constant cpumask width, this introduces three different cpumask "sizes": - the exact size (nr_cpumask_bits) remains identical to nr_cpu_ids. This is used for situations where we should use the exact size. - the "small" size (small_cpumask_bits) is the NR_CPUS constant if it fits in a single word and the bitmap operations thus end up able to trigger the "small_const_nbits()" optimizations. This is used for the operations that have optimized single-word cases that get inlined, notably the bit find and scanning functions. - the "large" size (large_cpumask_bits) is the NR_CPUS constant if it is an sufficiently small constant that makes simple "copy" and "clear" operations more efficient. This is arbitrarily set at four words or less. As a an example of this situation, without this fixed size optimization, cpumask_clear() will generate code like movl nr_cpu_ids(%rip), %edx addq $63, %rdx shrq $3, %rdx andl $-8, %edx callq memset@PLT on x86-64, because it would calculate the "exact" number of longwords that need to be cleared. In contrast, with this patch, using a MAX_CPU of 64 (which is quite a reasonable value to use), the above becomes a single movq $0,cpumask instruction instead, because instead of caring to figure out exactly how many CPU's the system has, it just knows that the cpumask will be a single word and can just clear it all. Note that this does end up tightening the rules a bit from the original version in another way: operations that set bits in the cpumask are now limited to the actual nr_cpu_ids limit, whereas we used to do the nr_cpumask_bits thing almost everywhere in the cpumask code. But if you just clear bits, or scan for bits, we can use the simpler compile-time constants. In the process, remove 'cpumask_complement()' and 'for_each_cpu_not()' which were not useful, and which fundamentally have to be limited to 'nr_cpu_ids'. Better remove them now than have somebody introduce use of them later. Of course, on x86-64 with MAXSMP there is no sane small compile-time constant for the cpumask sizes, and we end up using the actual CPU bits, and will generate the above kind of horrors regardless. Please don't use MAXSMP unless you really expect to have machines with thousands of cores. Signed-off-by:
