Merge tag 'tty-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty / serial driver updates from Greg KH: "Here is a small set of tty and serial driver updates for 6.13-rc1. Nothing major at all this time, only some small changes: - few device tree binding updates - 8250_exar serial driver updates - imx serial driver updates - sprd_serial driver updates - other tiny serial driver updates, full details in the shortlog All of these have been in linux-next for a while with one reported issue, but that commit has now been reverted" * tag 'tty-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (37 commits) Revert "serial: sh-sci: Clean sci_ports[0] after at earlycon exit" serial: amba-pl011: fix build regression dt-bindings: serial: Add a new compatible string for ums9632 serial: sprd: Add support for sc9632 tty/serial/altera_uart: unwrap error log string tty/serial/altera_jtaguart: unwrap error log string serial: amba-pl011: Fix RX stall when DMA is used tty: ldsic: fix tty_ldisc_autoload sysctl's proc_handler serial: 8250_fintek: Add support for F81216E serial: sh-sci: Clean sci_ports[0] after at earlycon exit tty: atmel_serial: Fix typo retreives to retrieves tty: atmel_serial: Use devm_platform_ioremap_resource() serial: 8250: omap: Move pm_runtime_get_sync tty: serial: samsung: Add Exynos8895 compatible dt-bindings: serial: samsung: Add samsung,exynos8895-uart compatible serial: 8250_dw: Add Sophgo SG2044 quirk dt-bindings: serial: snps-dw-apb-uart: Add Sophgo SG2044 uarts dt-bindings: serial: snps,dw-apb-uart: merge duplicate compatible entry. altera_jtaguart: Use dev_err() to report error attaching IRQ altera_uart: Use dev_err() to report error attaching IRQ handler ...
