It's not always true that the device_node of regulator can be found
at dev-of_node at the time when of_get_regulator_init_data() is being
called, because in some cases the regulator nodes in device tree do
not have 'struct device' behind them until regulator_dev gets created
for it by core

This driver works with both, static platform data and device tree
bindings. It has been tested on a TQM855L board with two AN82527
CAN controllers on the local bus.

Add an irqdomain for the AIC interrupt controller.
The device tree support is mapping the registers and
is using the irq_domain_simple_ops to manage hwirq
translation.
The documentation is describing the meaning of the
two cells required for using this interrupt-controller
in a device tree node.

Certainly. Many different threads actually. Here's a few:
When no platform data is supplied, point pdata at a default platform
structure. This enables two future changes:
a) Defines the default platform data values in a single place.
b) There is always a valid pdata pointer, so some conditional code can
be simplified by a later patch.
Based on work
The GPIO registers are 15 bits wide. Hence values, higher than 0x7fff are
not legal GPIO register values. Modify the pdata.gpio_cfg handling code
to reject all illegal values, not just WM8903_GPIO_NO_CONFIG (0x8000). This
will allow the later use of 0x as an invalid value in future device
Modify wm8903_init_gpio() so that it's passed the pdata structure rather
than extracting it from the platform device. This allows the caller to
pass in a default pdata structure when the platform device didn't contain
one. wm8903_init_gpio() now uses the centralized default gpio_base
definition
If the WM8903 is hooked up to an interrupt, set the irq_active_low flag
in the default platform data based on the IRQ's IRQ_TYPE. Map IRQ_TYPE_NONE
(a lack of explicit configuration/restriction) to irq_active_low = false;
the previous default.
This code is mainly added to support device tree
Document the device tree binding for the WM8903 codec, and modify the
driver to extract platform data from the device tree, if present.
Based on work by John Bonesio, but significantly reworked since then.

No need to set things to zero (or just memset the structure).
