Merge tag 'tty-6.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty / serial / console fixes from Greg KH: "Here are a bunch of fixes/reverts for 6.10-rc6. Include in here are: - revert the bunch of tty/serial/console changes that landed in -rc1 that didn't quite work properly yet. Everyone agreed to just revert them for now and will work on making them better for a future release instead of trying to quick fix the existing changes this late in the release cycle - 8250 driver port count bugfix - Other tiny serial port bugfixes for reported issues All of these have been in linux-next this week with no reported issues" * tag 'tty-6.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: Revert "printk: Save console options for add_preferred_console_match()" Revert "printk: Don't try to parse DEVNAME:0.0 console options" Revert "printk: Flag register_console() if console is set on command line" Revert "serial: core: Add support for DEVNAME:0.0 style naming for kernel console" Revert "serial: core: Handle serial console options" Revert "serial: 8250: Add preferred console in serial8250_isa_init_ports()" Revert "Documentation: kernel-parameters: Add DEVNAME:0.0 format for serial ports" Revert "serial: 8250: Fix add preferred console for serial8250_isa_init_ports()" Revert "serial: core: Fix ifdef for serial base console functions" serial: bcm63xx-uart: fix tx after conversion to uart_port_tx_limited() serial: core: introduce uart_port_tx_limited_flags() Revert "serial: core: only stop transmit when HW fifo is empty" serial: imx: set receiver level before starting uart tty: mcf: MCF54418 has 10 UARTS serial: 8250_omap: Implementation of Errata i2310 tty: serial: 8250: Fix port count mismatch with the device

- <DEVNAME>:<n>.<n>[,options]
- Use the specified serial port on the serial core bus.
- The addressing uses DEVNAME of the physical serial port
- device, followed by the serial core controller instance,
- and the serial port instance. The options are the same
- as documented for the ttyS addressing above.
-
- The mapping of the serial ports to the tty instances
- can be viewed with:
-
- $ ls -d /sys/bus/serial-base/devices/*:*.*/tty/*
- /sys/bus/serial-base/devices/00:04:0.0/tty/ttyS0
-
- In the above example, the console can be addressed with
- console=00:04:0.0. Note that a console addressed this
- way will only get added when the related device driver
- is ready. The use of an earlycon parameter in addition to
- the console may be desired for console output early on.
