Merge tag 'tty-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty and serial updates from Greg KH: "Here is the big tty and serial patch set for 4.9-rc1. It also includes some drivers/dma/ changes, as those were needed by some serial drivers, and they were all acked by the DMA maintainer. Also in here is the long-suffering ACPI SPCR patchset, which was passed around from maintainer to maintainer like a hot-potato. Seems I was the sucker^Wlucky one. All of those patches have been acked by the various subsystem maintainers as well. All of this has been in linux-next with no reported issues" * tag 'tty-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (111 commits) Revert "serial: pl011: add console matching function" MAINTAINERS: update entry for atmel_serial driver serial: pl011: add console matching function ARM64: ACPI: enable ACPI_SPCR_TABLE ACPI: parse SPCR and enable matching console of/serial: move earlycon early_param handling to serial Revert "drivers/tty: Explicitly pass current to show_stack" tty: amba-pl011: Don't complain on -EPROBE_DEFER when no irq nios2: dts: 10m50: Add tx-threshold parameter serial: 8250: Set Altera 16550 TX FIFO Threshold serial: 8250: of: Load TX FIFO Threshold from DT Documentation: dt: serial: Add TX FIFO threshold parameter drivers/tty: Explicitly pass current to show_stack serial: imx: Fix DCD reading serial: stm32: mark symbols static where possible serial: xuartps: Add some register initialisation to cdns_early_console_setup() serial: xuartps: Removed unwanted checks while reading the error conditions serial: xuartps: Rewrite the interrupt handling logic serial: stm32: use mapbase instead of membase for DMA tty/serial: atmel: fix fractional baud rate computation ...
