[PATCH v3 0/6] MIPS: alchemy: attach software nodes to GPIO controllers and use properties

[PATCH v3 0/6] MIPS: alchemy: attach software nodes to GPIO controllers and use properties

[Bartosz Golaszewski]

This series of patches updates board previously converted to use static
device properties/software nodes to attach and use nodes attached to the
respective gpiochip devices rather than simply defining unattached
software nodes with matching name. This is a requirement of newer
gpiolib code. Note that there is currently a workaround preserving the
lookup based on the software node name, but it will be removed soon.

The additional 4 patches convert the remaining 2 boards to use software
nodes as well and fix some build warnings.

[PATCH v3 2/6] MIPS: alchemy: provide visible function prototypes to board files

[Bartosz Golaszewski]

Board files under arch/mips/alchemy/ define functions called from
db1xxx.c but their prototypes are only in that .c file instead of being
declared in a common header. This causes several build warnings about
missing prototypes. Provide these prototypes in a new header and include
it where necessary.

[PATCH v3 3/6] MIPS: alchemy: mtx1: attach software nodes to GPIO chips

[Bartosz Golaszewski]

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

GPIO subsystem is switching the way it locates GPIO chip instances for
GPIO references in software nodes from matching on node names to
identity matching, which necessitates assigning firmware nodes
(software nodes) to GPIO chips.

Move the node definitions for alchemy-gpio1 and alchemy-gpio2 to
arch/misp/alchemy/common/gpiolib.c, register them there, and attach
them to gpio_chip instances. Adjust MTX1 board file to use these nodes.

Note that because nodes need to be registered before they can be used in
PROPERTY_ENTRY_GPIO() we have to do the registration at
postcore_initcall level, otherwise (due to the link order) MTX1 board
initialization code will run first.

[PATCH v3 4/6] MIPS: alchemy: db1000: use nodes attached to GPIO chips in properties

[Bartosz Golaszewski]

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

GPIO subsystem is switching the way it locates GPIO chip instances for
GPIO references in software nodes by doing identity matching instead of
matching on node names. Switch to using software nodes attached to gpio
chips instead of using freestanding software nodes.

Also stop supplying platform data for the spi-gpio controller since
spi-gpio driver can derive number of chipselect lines from device
properties.

[PATCH v3 5/6] MIPS: alchemy: gpr: switch to static device properties

[Bartosz Golaszewski]

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

Convert I2C-gpio device and GPIO-connected LEDs on GPR board to software
nodes/properties, so that support for platform data can be removed from
gpio-leds driver (which will rely purely on generic device properties
for configuration).
