Pull tty and serial driver updates from Greg KH: "Here is the big set of tty and serial driver updates for 5.19-rc1. Lots of tiny cleanups in here, the major stuff is: - termbit cleanups and unification by Ilpo. A much needed change that goes a long way to making things simpler for all of the different arches - tty documentation cleanups and movements to their own place in the documentation tree - old tty driver cleanups and fixes from Jiri to bring some existing drivers into the modern world - RS485 cleanups and unifications to make it easier for individual drivers to support this mode instead of having to duplicate logic in each driver - Lots of 8250 driver updates and additions - new device id additions - n_gsm continued fixes and cleanups - other minor serial driver updates and cleanups All of these have been in linux-next for weeks with no reported issues" * tag 'tty-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (166 commits) tty: Rework receive flow control char logic pcmcia: synclink_cs: Don't allow CS5-6 serial: stm32-usart: Correct CSIZE, bits, and parity serial: st-asc: Sanitize CSIZE and correct PARENB for CS7 serial: sifive: Sanitize CSIZE and c_iflag serial: sh-sci: Don't allow CS5-6 serial: txx9: Don't allow CS5-6 serial: rda-uart: Don't allow CS5-6 serial: digicolor-usart: Don't allow CS5-6 serial: uartlite: Fix BRKINT clearing serial: cpm_uart: Fix build error without CONFIG_SERIAL_CPM_CONSOLE serial: core: Do stop_rx in suspend path for console if console_suspend is disabled tty: serial: qcom-geni-serial: Remove uart frequency table.

dt-bindings: Fix properties without any type

2022-05-23T16:53:30+00:00

Now that the schema tools can extract type information for all properties (in order to decode dtb files), finding properties missing any type definition is fairly trivial though not yet automated. Fix the various property schemas which are missing a type. Most of these tend to be device specific properties which don't have a vendor prefix. A vendor prefix is how we normally ensure a type is defined.

dt-bindings: serial: renesas,em-uart: Add RZ/V2M clock to access the registers

2022-05-19T16:31:44+00:00

The RZ/V2M SoC has an additional clock to access the registers. The HW manual says this clock should not be touched as it is used by the "ISP Firmware".

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

2022-05-04T21:19:03+00:00

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: rs485: Add receiver enable polarity

2022-04-26T12:47:38+00:00

Add polarity property for receiver enable. Some UARTs have separate enable pins for tx (RTS or DE) and rx (RE). As most RS485 transceivers have !RE pin, the default is active low in contrast to rs485-rts-active-low that defaults to active high.
