blackfin: adi gpio driver and pinctrl driver support

2013-11-15T09:33:42+00:00

Remove gpio driver for new gpio controller on BF54x and BF60x.
Build the bfin_gpio driver only when other BF5xx processors are selected.
Replace the prefix of some gpio and peripheral functions with adi.
add portmux platform data in machine portmux.h

Blackfin: bfin_gpio: Use proper mask for comparing pfunc

2013-11-15T09:33:41+00:00

For BF537_FAMILY, when offset != 1, the mask is 1.
Thus add proper mask for comparing pfunc with function.

Also has small refactor for better readability.
In portmux_setup(), it looks odd having "pmux &= ~(3 << 1);"
while in current code we do pmux |= (function << offset);.

blackfin: delete __cpuinit usage from all blackfin 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/blackfin uses of the __cpuinit macros from
all C files.  Currently blackfin does not have any __CPUINIT used in
assembly files.

Pull VFS updates from Al Viro,

Misc cleanups all over the place, mainly wrt /proc interfaces (switch
create_proc_entry to proc_create(), get rid of the deprecated
create_proc_read_entry() in favor of using proc_create_data() and
seq_file etc).

7kloc removed.
