[PATCHv3 0/4] n_gsm serdev support and mfd driver for droid4 modem

[Tony Lindgren]

Hi all,

Here's v3 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 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
