Merge tag 'tty-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial driver updates from Greg KH: "Even in this age, people are still making new serial port silicon, why... Anyway, here's the TTY and Serial driver update for 5.4-rc1. Lots of changes in here for a number of embedded serial port devices that are being worked on because people really like to see those console logs... Other than that, nothing major here, no core tty changes that anyone should care about. All of these have been in linux-next for a while with no reported issues" * tag 'tty-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (125 commits) serial: tegra: Add PIO mode support serial: tegra: report clk rate errors serial: tegra: add support to adjust baud rate serial: tegra: DT for Adjusted baud rates serial: tegra: add support to use 8 bytes trigger serial: tegra: set maximum num of uart ports to 8 serial: tegra: check for FIFO mode enabled status dt-binding: serial: tegra: add new chips serial: tegra: report error to upper tty layer serial: tegra: flush the RX fifo on frame error serial: tegra: avoid reg access when clk disabled serial: tegra: add support to ignore read serial: sprd: correct the wrong sequence of arguments dt-bindings: serial: Convert riscv,sifive-serial to json-schema serial: max310x: turn off transmitter before activating AutoCTS or auto transmitter flow control serial: max310x: Properly set flags in AutoCTS mode tty: serial: fix platform_no_drv_owner.cocci warnings dt-bindings: serial: Document Freescale LINFlexD UART serial: fsl_linflexuart: Update compatible string tty: n_gsm: avoid recursive locking with async port hangup ...
