Merge tag 'tty-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
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. Full details in the shortlog. All of these have been in linux-next for a while with no reported issues" * tag 'tty-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (102 commits) serial: cpm_uart: Don't request IRQ too early for console port tty: serial: do unlock on a common path in altera_jtaguart_console_putc() tty: serial: unify TX space reads under altera_jtaguart_tx_space() tty: serial: use FIELD_GET() in lqasc_tx_ready() tty: serial: extend lqasc_tx_ready() to lqasc_console_putchar() tty: serial: allow pxa.c to be COMPILE_TESTed serial: stm32: Fix unused-variable warning tty: serial: atmel: Add COMMON_CLK dependency to SERIAL_ATMEL serial: 8250: Fix restoring termios speed after suspend serial: Deassert Transmit Enable on probe in driver-specific way serial: 8250_dma: Convert to use uart_xmit_advance() serial: 8250_omap: Convert to use uart_xmit_advance() MAINTAINERS: Solve warning regarding inexistent atmel-usart binding serial: stm32: Deassert Transmit Enable on ->rs485_config() serial: ar933x: Deassert Transmit Enable on ->rs485_config() tty: serial: atmel: Use FIELD_PREP/FIELD_GET tty: serial: atmel: Make the driver aware of the existence of GCLK tty: serial: atmel: Only divide Clock Divisor if the IP is USART tty: serial: atmel: Separate mode clearing between UART and USART dt-bindings: serial: atmel,at91-usart: Add gclk as a possible USART clock ...
