The remoteproc driver needs explicit control of the DSP's reset line.

Thomas Petazzoni [Tue, 20 Nov 2012 22:00:52 +0000 (23:00 +0100)]
irqchip: add basic infrastructure

With the recent creation of the drivers/irqchip/ directory, it is
desirable to move irq controller drivers here. At the moment, the only
driver here is irq-bcm2835, the driver for the irq controller found in
the ARM BCM2835 SoC, present in Rasberry Pi systems. This irq
controller driver was exporting its initialization function and its
irq handling function through a header file in
<linux/irqchip/bcm2835.h>.

When proposing to also move another irq controller driver in
drivers/irqchip, Rob Herring raised the very valid point that moving
things to drivers/irqchip was good in order to remove more stuff from
arch/arm, but if it means adding gazillions of headers files in
include/linux/irqchip/, it would not be very nice.

So, upon the suggestion of Rob Herring and Arnd Bergmann, this commit
introduces a small infrastructure that defines a central
irqchip_init() function in drivers/irqchip/irqchip.c, which is meant
to be called as the ->init_irq() callback of ARM platforms. This
function calls of_irq_init() with an array of match strings and init
functions generated from a special linker section.

Note that the irq controller driver initialization function is
responsible for setting the global handle_arch_irq() variable, so that
ARM platforms no longer have to define the ->handle_irq field in their
DT_MACHINE structure.

A global header, <linux/irqchip.h> is also added to expose the single
irqchip_init() function to the reset of the kernel.

A further commit moves the BCM2835 irq controller driver to this new
small infrastructure, therefore removing the include/linux/irqchip/
directory.

ARM/...: timer and clock events cleanup, and remove struct sys_timer

This branch contains a number of cleanups and unifications to various
timer- clock-events- and ARM timer code. The main points are:

1) Convert arch_gettimeoffset to a pointer, so that architectures with
   multiple timer implementations can simply set this standard pointer
   rather than maintaining their own arch-specific pointers for the
   same purpose. Various architectures are converted to using this new
   feature.

2) Conversion of ARM timer implementations to use clock_event_devices's
   suspend/resume operations, rather than the ARM-specific sys_timer
   versions. Thus, the ARM code begins to use more common infra-structure
   rather than arch-specific code.

3) Removal of ARM's struct sys_timer completely, now that everything uses
   common code.

4) Introduction of drivers/clocksource/clksrc-of.c, which allows ARM clock
   source implementations to be moved into drivers/clocksource, with the
   need to add SoC-specific header files for each timer initialization
   function; instead, all enabled implementations are registered into a
   table which a single core function iterates over, and calls the
   relevant initialization functions based on device tree. At least the
   Tegra and BCM2835 clocksource implementations will use this feature in
   the 3.9 kernel cycle.
