This makes the gpio-exar driver usable, which was prevented by a number of fatal bugs, and adds support for the SIMATIC IOT2040 to the 8250-exar driver and, indirectly, to gpio-exar as well. It's a cross-subsystem series, so I'm also cross-posting to the serial and gpio lists.
Changes in v2: - dropped already merged patches - switched to platform_data structure for exar <-> gpio driver communication - use dmi_check_system() to express platform match - adjusted bit logic style in exar_get_direction/value Jan Jan Kiszka (6): gpio: exar: Fix passing in of parent PCI device gpio: exar: Allocate resources on behalf of the platform device gpio: exar: Fix iomap request gpio: exar: Fix reading of directions and values gpio-exar/8250-exar: Make set of exported GPIOs configurable serial: exar: Add support for IOT2040 device drivers/gpio/gpio-exar.c | 54 +++++++----- drivers/tty/serial/8250/8250_exar.c | 151 ++++++++++++++++++++++++++++++-- include/linux/platform_data/gpio-exar.h | 25 ++++++ 3 files changed, 198 insertions(+), 32 deletions(-) create mode 100644 include/linux/platform_data/gpio-exar.h -- 2.12.0
