2020-09-16docs: Document cross-referencing between documentation pagesNícolas F. R. A. Prado1-0/+17
The syntax to cross-reference between documentation pages wasn't documented anywhere. Document the cross-referencing using the new automarkup for Documentation/... and also Sphinx's doc directive for using relative paths. Signed-off-by: Nícolas F. R. A.

2020-09-16docs: Add automatic cross-reference for documentation pagesNícolas F. R. A. Prado1-1/+38
Cross-referencing to other documentation pages is possible using the :doc:`doc-file` directive from Sphinx. Add automatic markup for references to other documentation pages in the format Documentation/subfolder/doc-file.rst (the extension being optional). This requires that the path be passed all the way from the Documentation folder, which can be longer than passing a relative path through the :doc: directive, but avoids the markup, making the text cleaner when read in plain text.

2020-09-16docs: Allow multiple automarkup functionsNícolas F. R. A. Prado1-42/+55
The automarkup script previously matched expressions and substituted them with markup to enable automatic cross-reference all in the same function. Split the expression matching iteration and the markup substitution into different functions to make it easier to add new regular expressions and functions to treat each of them.

A single list of versions for a hierarchy of hardware levels is not sufficient in some cases. For example, if the hardware version has two levels, i.e. X.Y and we want an OPP to support only version 2.1 and 1.2, we will set the property as: opp-supported-hw = <0x00000003 0x00000003>; What this also does is enable hardware versions 2.2 and 1.1, which we don't want. Extend the property to accept multiple versions, so we can define the property as: opp-supported-hw = <0x00000002 0x00000001>, <0x00000001 0x00000002>; While at it, also reword the property description.

2020-09-15xfs: deprecate the V4 formatDarrick J. Wong1-0/+23
The V4 filesystem format contains known weaknesses in the on-disk format that make metadata verification diffiult. In addition, the format does not support dates past 2038 and will not be upgraded to do so. We should start the process of retiring the old format to close off attack surfaces and to encourage users to migrate onto V5. Therefore, make XFS V4 support a configurable option. For the first period it will be default Y in case some distributors want to withdraw support early; for the second period it will be default N so that anyone who wishes to continue support can do so; and after that, support will be removed from the kernel. Dates for these events have been added to the upstream kernel. Signed-off-by: Darrick J.

There is a bug in the device tree binding for cznic,turris-omnia-leds which causes make dt_binding_check to complain. The reason is that the multi-led property binding's regular expression does not contain the `@` character, while the example nodes do. Fix this, and also adjust the maximum address to 'b' as there are 12 LEDs.

2020-09-15ethtool: add standard pause statsJakub Kicinski1-0/+11
Currently drivers have to report their pause frames statistics via ethtool -S, and there is a wide variety of names used for these statistics. Add the two statistics defined in IEEE 802.3x to the standard API. Create a new ethtool request header flag for including statistics in the response to GET commands. Always create the ETHTOOL_A_PAUSE_STATS nest in replies when flag is set. Testing if driver declares the op is not a reliable way of checking if any stats will actually be included and therefore we don't want to give the impression that presence of ETHTOOL_A_PAUSE_STATS indicates driver support. Note that this patch does not include PFC counters, which may fit better in dcbnl?

2020-09-15printk: ringbuffer: add finalization/extension supportJohn Ogness1-1/+2
Add support for extending the newest data block. For this, introduce a new finalization state (desc_finalized) denoting a committed descriptor that cannot be extended. Until a record is finalized, a writer can reopen that record to append new data. Reopening a record means transitioning from the desc_committed state back to the desc_reserved state. A writer can explicitly finalize a record if there is no intention of extending it. Also, records are automatically finalized when a new record is reserved. This relieves writers of needing to explicitly finalize while also making such records available to readers sooner. (Readers can only traverse finalized records.) Four new memory barrier pairs are introduced. Two of them are insignificant additions (data_realloc:A/desc_read:D and data_realloc:A/data_push_tail:B) because they are alternate path memory barriers that exactly match the purpose, pairing, and context of the two existing memory barrier pairs they provide an alternate path for. The other two new memory barrier pairs are significant additions: desc_reopen_last:A / _prb_commit:B - When reopening a descriptor, ensure the state transitions back to desc_reserved before fully trusting the descriptor data. _prb_commit:B / desc_reserve:D - When committing a descriptor, ensure the state transitions to desc_committed before checking the head ID to see if the descriptor needs to be finalized.

2020-09-15pinctrl: rza1: Switch to using "output-enable"Geert Uytterhoeven1-3/+2
For pins requiring software driven IO output operations, the RZ/A1 Pin Controller uses either the "output-high" or "output-low" DT property to enable the corresponding output buffer. The actual line value doesn't matter, as it is ignored. Commit 425562429d4f3b13 ("pinctrl: generic: Add output-enable property") introduced a new DT property for this specific use case. Update the RZ/A1 Pin Controller DT bindings and driver to use this new property instead. Preserve backwards compatibility with old DTBs in the driver, as this comes at a very small cost. Notes: - The DT binding examples already used the new property, - There are no upstream users of the old properties.

The clock controller schemas for i.MX 8M Mini, 8M Nano, 8M Plus and 8M Quad are basically the same. The only minor difference appears on 8M Quad which needs one more clock. There is no point to have four schemas for almost the same binding. Any fixes or changes would have to be duplicated four times.
