Subject: [PATCH 2/2 v7] pinmux: add a driver for the U300 pinmux
From: Linus Walleij <linus.walleij@...aro.org>
This adds a driver for the U300 pinmux portions of the system
controller "SYSCON". It also serves as an example of how to use
the pinmux subsystem. This driver also houses the platform data
for the only supported platform.
This deletes the old U300 driver in arch/arm/mach-u300 and
replace it with a driver using the new subsystem.
The new driver is considerably fatter than the old one, but it
also registers all 467 pins of the system and adds the power
and EMIF pin groups and corresponding functions. The idea
is to use this driver as a a reference for other
implementation so it needs to be as complete and verbose
as possible.
Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
---
ChangeLog v6->v7:
- Adjust the driver to return the group list as an array of
strings instead of a unsigned * array.
- Add support for the EMIF0 and EMIF1 pin groups.
- Acquire all muxmaps using pinmux hogs from the core using
a subsystem_initcall(). This way we need not change any
drivers or buses. We have the correct struct device *
pointers anyway so why not do it from there, and it
illustrates pretty well what the pinmux core will be able
to do once it can access the device tree.
- Use new convenience macros for system mappings.
- Unregister the GPIO range at removal.
