Pull tty/serial driver updates from Greg KH: "Here is the big set of TTY and Serial driver updates for 6.1-rc1. Lots of cleanups in here, no real new functionality this time around, with the diffstat being that we removed more lines than we added! Included in here are: - termios unification cleanups from Al Viro, it's nice to finally get this work done - tty serial transmit cleanups in various drivers in preparation for more cleanup and unification in future releases (that work was not ready for this release) - n_gsm fixes and updates - ktermios cleanups and code reductions - dt bindings json conversions and updates for new devices - some serial driver updates for new devices - lots of other tiny cleanups and janitorial stuff.

dt-bindings: Drop redundant 'maxItems/minItems' in if/then schemas

2022-05-04T21:19:03Z

Another round of removing redundant minItems/maxItems when 'items' list is specified. This time it is in if/then schemas as the meta-schema was failing to check this case. If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems.

dt-bindings: serial: samsung: Add ARTPEC-8 UART

2022-03-18T12:29:04Z

Add a compatible for the UART on the ARTPEC-8 SoC. This hardware block is closely related to the variants used on the Exynos chips. The register layout is identical to Exynos850 et al but the fifo size is different (64 bytes in each direction for all instances).

dt-bindings: Drop redundant minItems/maxItems

2021-06-21T19:56:46Z

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.
