1f5e6247ca ARM: OMAP2/3: VENC hwmods: Remove OCPIF_SWSUP_IDLE flag from VENC slave interface
The clocks for all DSS slave interfaces were recently changed to "dss_ick" on
OMAP2 and OMAP3, this clock can be autoidled by PRCM. The VENC interface
previously had "dss_54m_fck" as it's clock which couldn't be autoidled, and
hence the OCPIF_SWSUP_IDLE flag was needed.

Remove the OCPIF_SWSUP_IDLE flag from VENC interfaces as it's clock is
now "dss_ick".  This allows the PRCM hardware to autoidle the VENC
interface clocks when they are not active, rather than relying on the
software to do it, which can keep the interface clocks active
unnecessarily.

3c55c1baff ARM: OMAP2+: hwmod: Revert "ARM: OMAP2+: hwmod: Make omap_hwmod_softreset wait for reset status"
This reverts commit f9a2f9c3fa.  This
commit caused a regression in the I2C hwmod reset on OMAP2/3/4,
logging messages similar to these during boot:

[    0.200378] omap_hwmod: i2c1: softreset failed (waited 10000 usec)
[    0.222076] omap_hwmod: i2c2: softreset failed (waited 10000 usec)

While the original patch was intended to fix some reset-related timing
issues, it's believed that these problems were actually fixed by
commit 2800852a07 ("ARM: OMAP2+: hwmod:
Restore sysc after a reset"):

d99de7f552 ARM: OMAP2+: hwmod: add softreset delay field and OMAP4 data
Due to HW limitation, some IPs should not be accessed just after a
softreset. Since the current hwmod sequence is accessing the sysconfig
register just after the reset, it might lead to OCP bus error in
that case.

Add a new field in the sysconfig structure to specify a delay in usecs
needed after doing a softreset.

In the case of the ISS and FDIF modules, the L3 OCP port will be
disconnected upon a SW reset. That issue was confirmed with HW simulation
and an errata should be available soon. The HW recommendation to avoid
that is to wait for 100 OCP clk cycles, before accessing the IP.

Considering the worse case (OPP50), the L3 bus will run at 100 MHz,
so a 1 usec delay is needed. Add an x2 margin to be safe.

314489bd4c ARM: SoC fixes for 3.4-rc2
A bunch of fixes for regressions (and a few other problems) in 3.4-rc1:
 
 * Fix for regression of mach/io.h cleanup on platforms with PCI or PCMCIA
   (adding back the include file on those for now)
 * AT91 fixes for usb and spi
 * smsc911x ethernet fixes for i.MX
 * smsc911x fixes for OMAP
 * gpio fixes for Tegra
 * A handful of build error and warning fixes for various platforms
 * cpufreq kconfig dependencies, build and lowlevel debug fixes for
   Samsung platforms
 
 In other words, more or less the regular collection of -rc1/2 type
 material. A few of them, in particular the smsc911x for OMAP series, aren't
 technically regressions for 3.4, but they're valid fixes and we're still
 relatively early in the rc cycle so it seems appropriate to include them.

234e340582 simple_open: automatically convert to simple_open()
Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op.  This leads to a
proliferation of the default_open() implementation across the entire
tree.

Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().

This replacement was done with the following semantic patch:

<smpl>
@ open @
identifier open_f != simple_open;
identifier i, f;
@@
-int open_f(struct inode *i, struct file *f)
-{
(
-if (i->i_private)
-f->private_data = i->i_private;
|
-f->private_data = i->i_private;
)
-return 0;
-}

@ has_open depends on open @
identifier fops;
identifier open.open_f;

struct file_operations fops = {
...
-.open = open_f,
+.open = simple_open,

1ac02d7958 ARM: fix __io macro for PCMCIA
With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was
broken. PCMCIA depends on __io() returning a valid i/o address, and most
ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This
needs a better fix with a fixed i/o address mapping, but for now we just
restore things to the previous behavior.

This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled,
but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff,
so it doesn't need an io.h.

Basically the regulators must be per board file as the regulators

down gpmc-smsc911x.c to not even care about the regulators.

clkdm/pwrdm for USB DPLL (l3init) is turned on before attempting
a DPLL relock. So, mark the database accordingly.

Without this fix, it was seen that DPLL relock fails while testing
relock in a loop of USB DPLL.

8b8c3c7895 ARM: OMAP2+: powerdomain: Wait for powerdomain transition in pwrdm_state_switch()
Commit b1cbdb00d ("OMAP: clockdomain: Wait for powerdomain to be ON
when using clockdomain force wakeup") was assuming that
pwrdm_state_switch() does wait for the powerdomain transition which is
not the case.  The missing wait for the powerdomain transition
violates the sequence which the hardware expects, which causes power
management failures on some devices.

Fix this API by adding the pwrdm_wait_transition().

0eb4fd9b3e ARM: OMAP: clock: fix race in disable all clocks
clk_disable_unused is invoked when CONFIG_OMAP_RESET_CLOCKS=y.
Since clk_disable_unused is called as lateinitcall, there can
be more than a few workqueues executing off secondary CPU(s).
The current code does the following:
a) checks if clk is unused
b) holds lock
c) disables clk
d) unlocks

Between (a) and (b) being executed on CPU0, It is possible to
have a driver executing on CPU1 which could do a get_sync->clk_get
(and increase the use_count) of the clock which was just about
to be disabled by clk_disable_unused.

We ensure instead that the entire list traversal is protected by
the lock allowing for parent child clock traversal which could be
potentially be done by runtime operations to be safe as well.

ac387330a6 ARM: OMAP3xxx: clock data: fix DPLL4 CLKSEL masks
Commit 2a9f5a4d45 "OMAP3 clock: remove unnecessary duplicate of dpll4_m2_ck,
added for 36xx" consolidated dpll4 clock structures between 34xx and 36xx,
but left 34xx CLKSEL masks for most dpll4 related clocks, which causes
clock code to not behave correctly when booting on DM3730 with higher
(36xx only) divisors set:
[    0.000000] WARNING: at arch/arm/mach-omap2/clkt_clksel.c:375 omap2_init_clksel_parent+0x104/0x114()

[    0.000000] clock: Could not find fieldval 0 for clock dpll4_m3_ck parent dpll4_ck

Fix this by switching to 36xx masks, as valid divisors will be limited
by clksel_rate lists.

26c547fd13 ARM: OMAP3xxx: HSMMC: avoid erratum workaround when transceiver is attached
If transceiver is attached to a MMC host of ES2.1 OMAP35xx, it seems
2.1.1.128 erratum doesn't apply and there is no data corruption,
probably because of different signal timing. The workaround for this
erratum disables multiblock reads, which causes dramatic loss of
performance (over 75% slower), so avoid it when transceiver is present.
