sh: Make intc messages consistent via pr_fmt.

2010-06-02T09:10:00+00:00

Wrapping pr_fmt to the KBUILD_MODNAME prefix seems to be the trendy
thing to do these days, so just do that instead of manually tidying
up the stragglers.

ARM: mach-shmobile: Use shared clock framework

2010-05-20T03:05:45+00:00

Teach SH-Mobile ARM how to make use of the shared SH clock
framework. This commit is one atomic switch that dumps the
local hackery and instead links in the shared clock framework
code in drivers/sh. A few local functions are kept in clock.c.

sh: move sh clock-cpg.c contents to drivers/sh/clk-cpg.c

2010-05-13T08:39:22+00:00

Move the CPG helpers to drivers/sh/clk-cpg.c V2.

This to allow SH-Mobile ARM to share the code with
SH. All functions except the legacy CPG stuff is moved.

sh: move sh clock.c contents to drivers/sh/clk.

2010-05-13T08:39:14+00:00

This patch is V2 of the SH clock framework move from
arch/sh/kernel/cpu/clock.c to drivers/sh/clk.c. All
code except the following functions are moved:
clk_init(), clk_get() and clk_put().

The init function is still kept in clock.c since it
depends on the SH-specific machvec implementation.

The symbols clk_get() and clk_put() already exist in
the common ARM clkdev code, those symbols are left in
the SH tree to avoid duplicating them for SH-Mobile ARM.

sh: intc: IRQ auto-distribution support.

2010-04-15T04:13:52+00:00

This implements support for hardware-managed IRQ balancing as implemented
by SH-X3 cores (presently only hooked up for SH7786, but can probably be
carried over to other SH-X3 cores, too).

CPUs need to specify their distribution register along with the mask
definitions, as these follow the same format. Peripheral IRQs that don't
opt out of balancing will be automatically distributed at the whim of the
hardware block, while each CPU needs to verify whether it is handling the
IRQ or not, especially before clearing the mask.

sh: intc: userimask support.

2010-04-13T05:43:03+00:00

This adds support for hardware-assisted userspace irq masking for
special priority levels. Due to the SR.IMASK interactivity, only some
platforms implement this in hardware (including but not limited to
SH-4A interrupt controllers, and ARM-based SH-Mobile CPUs). Each CPU
needs to wire this up on its own, for now only SH7786 is wired up as an
example.
