ARM: 6483/1: arm & sh: factorised duplicated clkdev.c

2010-11-26T10:51:04+00:00

factorise some generic infrastructure to assist looking up struct clks
for the ARM & SH architecture.

as the code is identical at 99%

put the arch specific code for allocation as example in asm/clkdev.h

OMAP1: clock: some cleanup

2010-07-26T22:34:28+00:00

Convert most of the magic numbers in mach-omap1/clock_data.c to use
macros.  Clean up a few comments to conform with Documentation/CodingStyle.
Mark the current clkops_uart as being OMAP16xx-only, and add some comments
to indicate that it does not belong there, for future cleanup.

This patch should not cause any functional changes.

OMAP1 clock: fix section mismatch on clk_init

2010-05-20T18:31:04+00:00

remove the section annotation from omap1_clk_disable_unused()
to kill the section mismatch warning.

OMAP4: clock: Add dummy clock nodes for interface clocks

2010-02-25T00:45:17+00:00

On OMAP4 platform the iclk control is completly under hardware control
and no software control is available.

This difference w.r.t previous OMAP's needs all the common driver
accross OMAP's , cpu_is_xxxx() checks. To avoid poulluting the
drivers dummy clock nodes are created (The autogeneration
script has been updated accordingly).

OMAP clock: drop RATE_FIXED clock flag

2010-02-24T19:29:43+00:00

The RATE_FIXED clock flag is pointless.  In the OMAP1 clock code, it
simply causes the omap1_clk_round_rate() function to return the
current rate of the clock.  omap1_clk_round_rate(), however, should
never be called for a fixed-rate clock, since none of these clocks
have a .round_rate function pointer set in their struct clk records.
Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes
the clock code to emit a warning if the OMAP clock maintainer was
foolish enough to add a .round_rate function pointer to a fixed-rate
clock.  "Doctor, it hurts when I pretend that a fixed-rate clock is
rate-changeable."  "Then don't pretend that a fixed-rate clock is
rate-changeable."  It has no functional value.  This patch drops the
RATE_FIXED clock flag, removing it from all clocks that are so marked.

OMAP1 clock: convert armwdt_ck to use the fixed divisor recalc function

2010-01-27T03:12:57+00:00

The armwdt_ck clock uses a fixed divisor, so it can use the OMAP clock
fixed divisor recalculation code, rather than a custom function.

OMAP1 clock: fix for "BUG: spinlock lockup on CPU#0"

2010-01-20T20:35:28+00:00

Commit 52650505fbf3a6ab851c801f54e73e76c55ab8da caused clock initialization
to fail on OMAP1 with "BUG: spinlock lockup on CPU#0" -- this is because
omap1_select_table_rate() and omap1_round_to_table_rate() call clk_get_rate()
with the clockfw spinlock held.  Fix by accessing the rate directly from
the internal clock framework functions.

Thanks to Tony Lindgren  for reporting and testing the fix.

OMAP1 clock: convert mach-omap1/clock.h to mach-omap1/clock_data.c

2009-12-12T00:00:40+00:00

The OMAP1 clock code currently #includes a large .h file full of static
data structures.  Instead, define the data in a .c file.

Russell King  proposed this new arrangement:

    http://marc.info/?l=linux-omap&m=125967425908895&w=2

This patch also deals with most of the flagrant checkpatch violations.

While here, separate the mpu_rate data structures out into their own
files, opp.h and opp_data.c.  In the long run, these mpu_rate tables
should be replaced with OPP code.

Also includes a patch from Felipe Balbi  to
mark omap1_clk_functions as __initdata to avoid a section warning:

OMAP1 clock: convert test in disable_unused() to use ENABLE_ON_INIT

2009-12-12T00:00:40+00:00

mach-omap1/clock.c:omap1_clk_disable_unused() contains a test that
assumes that the clock structures are available in the file's
namespace.  After a following patch, this will no longer be the case.
So we need to reimplement that test.  It turns out that we already
have a facility in the clock framework to handle this case - the
ENABLE_ON_INIT flag - used on OMAP2/3.  Remove the offending test and
mark the clocks that it was intended to catch as ENABLE_ON_INIT.

OMAP1/2/3 clock: remove paranoid checks in preparation for clock{,2xxx,3xxx}_data.c

2009-12-11T23:12:07+00:00

Some parts of the clock code took advantage of the fact that the statically
allocated clock tree was in clock{,24xx,34xx}.c's local namespace to do some
extra argument checks.  These are overzealous and are more difficult to
maintain when the clock tree is in a separate namespace, so, remove them.
