Pull tty/serial driver updates from Greg KH: "Here is the big set of tty and serial driver patches for 4.17-rc1 Not all that big really, most are just small fixes and additions to existing drivers. There's a bunch of work on the imx serial driver recently for some reason, and a new embedded serial driver added as well. Full details are in the shortlog. All of these have been in the linux-next tree for a while with no reported issues" * tag 'tty-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (66 commits) serial: expose buf_overrun count through proc interface serial: mvebu-uart: fix tx lost characters tty: serial: msm_geni_serial: Fix return value check in qcom_geni_serial_probe() tty: serial: msm_geni_serial: Add serial driver support for GENI based QUP 8250-men-mcb: add support for 16z025 and 16z057 powerpc: Mark the variable earlycon_acpi_spcr_enable maybe_unused serial: stm32: fix initialization of RS485 mode ARM: dts: STi: Remove "console=ttyASN" from bootargs for STi boards vt: change SGR 21 to follow the standards serdev: Fix typo in serdev_device_alloc ARM: dts: STi: Fix aliases property name for STi boards tty: st-asc: Update tty alias serial: stm32: add support for RS485 hardware control mode dt-bindings: serial: stm32: add RS485 optional properties selftests: add devpts selftests devpts: comment devpts_mntget() devpts: resolve devpts bind-mounts devpts: hoist out check for DEVPTS_SUPER_MAGIC serial: 8250: Add Nuvoton NPCM UART serial: mxs-auart: disable clks of Alphascale ASM9260 ...

serial: remove tile uart driver

2018-03-26T13:57:22+00:00

The tile architecture is getting removed, and this driver is useless without it. Acked-by: Greg Kroah-Hartman Signed-off-by: Arnd Bergmann

serial: remove m32r_sio driver

2018-03-26T13:57:21+00:00

The m32r architecture is getting removed, so we don't need this any more. Acked-by: Nicolas Pitre Acked-by: Greg Kroah-Hartman Signed-off-by: Arnd Bergmann

serial: remove blackfin drivers

2018-03-26T13:57:19+00:00

The blackfin architecture is getting removed, so both the bfin_uart and bfin_sport_uart can be removed as well. Acked-by: Greg Kroah-Hartman Acked-by: Aaron Wu Signed-off-by: Arnd Bergmann

serial: remove cris/etrax uart drivers

2018-03-26T13:57:17+00:00

The cris architecture is getting removed, so we don't need the uart driver any more. Acked-by: Greg Kroah-Hartman Acked-by: Jesper Nilsson Signed-off-by: Arnd Bergmann

tty: serial: msm_geni_serial: Add serial driver support for GENI based QUP

2018-03-20T08:13:15+00:00

This driver supports GENI based UART Controller in the Qualcomm SOCs. The Qualcomm Generic Interface (GENI) is a programmable module supporting a wide range of serial interfaces including UART. This driver support console operations using FIFO mode of transfer.

tty: serial: sh-sci: Add default for number of ports for compile-testing

2017-12-18T09:28:31+00:00

When compile-testing an allmodconfig kernel for a platform without sh-sci serial ports, the SERIAL_SH_SCI_NR_UARTS symbol of type "int" doesn't get assigned a numerical default value, but an empty string, leading to a build failure: .config:3814:warning: symbol value '' invalid for SERIAL_SH_SCI_NR_UARTS ... make[3]: *** [silentoldconfig] Error 1 Fix this by explicitly providing a default value of 2, like before.

tty: serial: sh-sci: Hide DMA config question

2017-12-15T19:24:14+00:00

On most Renesas ARM platforms, the SCIF serial ports can be used with DMA, so most users will want DMA support to be enabled. On SuperH platforms, SCI(F) serial ports cannot be used with DMA yet (see also commit 219fb0c1436e4893 ("serial: sh-sci: Remove the platform data dma slave rx/tx channel IDs")), so users will want it disabled to reduce kernel size. Hence follow the above rationale to configure the default, unless CONFIG_EXPERT is enabled. Signed-off-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

tty: serial: sh-sci: Hide earlycon config question

2017-12-15T19:24:14+00:00

Renesas H8/300 and ARM platforms use DT and support earlycon, so most users want earlycon support to be enabled. On SuperH platforms, earlycon is not yet supported. Hence follow the above rationale to configure the default, unless CONFIG_EXPERT is enabled. Signed-off-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

tty: serial: sh-sci: Hide serial console config question

2017-12-15T19:24:14+00:00

Most users will want to use a serial console. Hence make that the default, unless CONFIG_EXPERT is enabled. Signed-off-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman
