This patch adds GPIO and IRQ support for the Diolan DLN-2 GPIO module.
Information about the USB protocol interface can be found in the
Programmer's Reference Manual [1], see section 2.9 for the GPIO
module commands and responses.

This patch adds support for the Diolan DLN-2 I2C master module. Due
to hardware limitations it does not support SMBUS quick commands.
Information about the USB protocol interface can be found in the
Programmer's Reference Manual [1], see section 6.2.2 for the I2C
master mod
This patch series adds support for Diolan USB-I2C/GPIO Master Adapter DLN-2.
Details about device can be found here:
https://www.diolan.com/i2c/i2c_interface.html.
Changes since v1:
* rewrite the drivers as an MFD
* rewrite the irq part of the gpio driver to use GPIOLIB_IRQCHIP
* cleanup t
This patch implements the USB part of the Diolan USB-I2C/SPI/GPIO
Master Adapter DLN-2. Details about the device can be found here:

Added flag to the GPIO chip so that IRQ from non-wakeup GPIO will

Use of unmask/mask in set_wake was an incorrect implementation. The new
implementation correctly sets wakeup for the gpio chip's IRQ so the gpio chip
will not sleep while wakeup-enabled gpio are in use.

Add an attribute 'wakeup' to the GPIO sysfs interface which allows
marking/unmarking a GPIO as wake IRQ.
The file 'wakeup' is created in each exported GPIOs directory, if an IRQ
is associated with that GPIO and the irqchip implements set_wake().
Writing 'enabled' to that file will enable wake for t
Hi Linus,
after our discussion during the push of the gpio-zynq driver, we took a
closer look at the LED and gpio_keys drivers.
For LEDs and other simple use-cases where you need to control an output,
that driver is great and a patch to get the LEDs on our boards added to
DT is pending.

There is currently a kludge to get the Makefile to move down
to sh-pfc:s drivers: the arch definitions are used twice to
get it done. However we can very well use the Kconfig symbol
for the SH PFC pin control feature itself: it doesn't matter
that it comes from a lower leaf in the Kconfig hierarchy
