Hi all, Here's v4 set of n_gsm serdev support patches, and the related MFD driver for the modem found on Motorola Mapphone phones and tablets like droid4. This series only adds basic character device support for the MFD driver. Other serdev consumer drivers for specific devices will be posted separately. The patches are against v5.6-rc1. Regards, Tony Changes since v3: - Update list of folks in Cc, looks like I sent v3 only to Lee and lkml - Init privdata before motmdm_register_dlci calls gsm_serdev_register_dlci - Update binding based on Rob's comments for license and "allOf" Changes since v2: - Drop useless send_command indirection, use static motmdm_send_command Changes since v1: - Simplified usage and got rid of few pointless inline functions - Added consumer MFD driver, devicetree binding, and dts changes Tony Lindgren (4): tty: n_gsm: Add support for serdev drivers mfd: motmdm: Add Motorola TS 27.010 serdev modem driver for droid4 dt-bindings: mfd: motmdm: Add binding for motorola-mdm ARM: dts: omap4-droid4: Enable basic modem support .../mfd/motorola,mapphone-mdm6600.yaml | 34 + .../boot/dts/motorola-mapphone-common.dtsi | 6 + drivers/mfd/Kconfig | 9 + drivers/mfd/Makefile | 1 + drivers/mfd/motorola-mdm.c | 1200 +++++++++++++++++ drivers/tty/n_gsm.c | 372 +++++ include/linux/serdev-gsm.h | 168 +++ 7 files changed, 1790 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/motorola,mapphone-mdm6600.yaml create mode 100644 drivers/mfd/motorola-mdm.c create mode 100644 include/linux/serdev-gsm.h -- 2.25.1
