Update references for the ACPI _DSD documentation.

2021-07-25docs: firmware-guide: acpi: dsd: graph.rst: replace some charactersMauro Carvalho Chehab1-1/+1
The conversion tools used during DocBook/LaTeX/html/Markdown->ReST conversion and some cut-and-pasted text contain some characters that aren't easily reachable on standard keyboards and/or could cause troubles when parsed by the documentation build system. Replace the occurences of the following characters: - U+00a0 (' '): NO-BREAK SPACE as it can cause lines being truncated on PDF output Acked-by: Rafael J.

2021-06-17docs: firmware-guide: acpi: avoid using ReST :doc:`foo` markupMauro Carvalho Chehab1-1/+1
The :doc:`foo` tag is auto-generated via automarkup.py. So, use the filename at the sources, instead of :doc:`foo`.

2020-07-27ACPI: Replace HTTP links with HTTPS onesAlexander A. Klimov1-5/+5
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2019-05-13Documentation: ACPI: Direct references are allowed to devices onlySakari Ailus1-6/+6
In ACPI it is possible to make references to device objects only, not to other objects inside a device. In practice this means that hierarchical data extension targets must be in parentheses to make them strings, or an ACPICA warning will be produced.
