pinctrl: meson: Drop pinctrl_unregister for devm_ registered device

2016-08-10T13:45:54+00:00

It's not necessary to unregister pin controller device registered
with devm_pinctrl_register() and using pinctrl_unregister() leads
to a double free.

This is detected by Coccinelle semantic patch.

pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map

2016-04-01T13:06:36+00:00

Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since
it does not depend on device tree despite the current name. This
will enforce a consistent naming in pinctr-utils.c and will make
it clear it can be called from outside device tree (e.g. from
ACPI handling code).

pinctrl: amlogic: Make driver independent from two-domain configuration

2016-03-09T06:00:28+00:00

In the Amlogic Meson8 / Meson8b platforms we have two different buses:
cbus and aobus, corresponding to 2 different power domains (regular and
always-on). On each bus a different set of registers is mapped to manage
muxes, GPIOs and in general to control a clear subset of the pins.

Considering this architecture, having two different pinctrl devices, one
for each bus / power domain, makes much more sense than just having one
single device.

Right now we have one single pin controller driver that uses two
different domains (represented by 'gpio' and 'gpio-ao' sub-nodes in the
DTS) to manage the set of registers on the two buses. This dual-domain
configuration is hardcoded into the driver that strictly requires one
domain for each bus in the same pin controller device.

With this patch we refactor the driver to allow splitting the driver in
two parts. This change is needed to have a proper description of the HW
in the device-tree where we want to introduce aobus and cbus.
