sh: Switch to new style TMU device

2014-05-11T10:35:27+00:00

The TMU (Timer Unit) driver implements a new style of platform data that
handles the timer as a single device with multiple channel. Switch from
the old-style platform data to the new-style platform data.

sh: Don't set plat_sci_port scbrr_algo_id field

2013-12-24T12:49:43+00:00

The field will be removed from the sh-sci driver. Don't set it and let
the driver handle baud rate calculation internally.

sh: Declare SCIF register base and IRQ as resources

2013-12-24T12:49:43+00:00

Passing the register base address and IRQ through platform data is
deprecated. Use resources instead.

sh: delete __cpuinit usage from all sh files

2013-07-14T23:36:53+00:00

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
are flagged as __cpuinit  -- so if we remove the __cpuinit from
arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
content into no-ops as early as possible, since that will get rid
of these warnings.  In any case, they are temporary and harmless.

This removes all the arch/sh uses of the __cpuinit macros from
all C files.  Currently sh does not have any __CPUINIT used in
assembly files.

sh: sh4: Change the specification method of IRQ to SCIx_IRQ_MUXED

2012-04-17T07:17:31+00:00

Some SCIF devices specify the same IRQ. We can use SCIx_IRQ_MUXED for this.
And change use to evt2irq(), without specifying the value of IRQ directly.
This is correction to the SH4 series.
