dt-bindings: arm: Trivial typo fixes in cpu-capacity.txt

2022-02-11T16:36:58Z

Correct the spelling of 'cluster1@max-freq' and fix the wrong capacity-dmips-mhz value 576 (which should be 578 instead). Signed-off-by: Zenghui Yu Signed-off-by: Rob Herring Link: https://lore.kernel.org/r/20220208070300.1610-1-yuzenghui@huawei.com

dt-bindings: arm: Clean up CPU binding examples

2019-05-22T14:01:02Z

Following commit 31af04cd60d3 ("arm64: dts: Remove inconsistent use of 'arm,armv8' compatible string"), clean up these binding examples in case anyone is tempted to copy them. CC: Linus Walleij Signed-off-by: Robin Murphy Signed-off-by: Rob Herring

doc: bindings: fix bad reference to ARM CPU bindings

2019-01-11T23:12:50Z

The primecell.txt and cpus.txt files were converted into YAML. This patch updates old references with new ones. Fixes: d3c207eeb905 ("dt-bindings: arm: Convert primecell binding to json-schema") Fixes: 672951cbd1b7 ("dt-bindings: arm: Convert cpu binding to json-schema") Signed-off-by: Otto Sabart Signed-off-by: Rob Herring

dt-bindings: arm: Explain capacities-dmips-mhz calculations in example

2018-10-30T22:14:36Z

The example contains two values for the capacity currently, 446 in text and 578 in code. The numbers are all correct but can confuse some of the readers. This patch tries to explain how the numbers are calculated to avoid same confusion going forward. Acked-by: Daniel Lezcano Signed-off-by: Viresh Kumar Signed-off-by: Rob Herring

arm64: dts: Fix various entry-method properties to reflect documentation

2018-08-24T15:50:02Z

The idle-states binding documentation[1] mentions that the 'entry-method' property is required on 64-bit platforms and must be set to "psci". commit a13f18f59d26 ("Documentation: arm: Fix typo in the idle-states bindings examples") attempted to fix this earlier but clearly more is needed. Fix the cpu-capacity.txt documentation that uses the incorrect value so we don't get copy-paste errors like these. Clarify the language in idle-states.txt by removing the reference to the psci bindings that might be causing this confusion. Finally, fix devicetrees of various boards to reflect current documentation.

Documentation: arm: define DT cpu capacity-dmips-mhz bindings

2016-11-07T18:15:03Z

ARM systems may be configured to have cpus with different power/performance characteristics within the same chip. In this case, additional information has to be made available to the kernel (the scheduler in particular) for it to be aware of such differences and take decisions accordingly. Therefore, this patch aims at standardizing cpu capacities device tree bindings for ARM platforms. Bindings define cpu capacity-dmips-mhz parameter, to allow operating systems to retrieve such information from the device tree and initialize related kernel structures, paving the way for common code in the kernel to deal with heterogeneity.
