80b517f362 omap: zoom: add mmc3/wl1271 device support
Add MMC3 support on ZOOM, which has the wl1271 device hardwired to.

The wl1271 is a 4-wire, 1.8V, embedded SDIO WLAN device with an
external IRQ line, and power-controlled by a GPIO-based fixed regulator.

3fea60261e Input: twl40300-keypad - fix handling of "all ground" rows
The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c)
defines a key map for the matrix keypad keyboard. The hardware seems to
use all of the 8 rows and 8 columns of the keypad, although not all
possible locations are used.

The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys
are defined with a row and column number between 0 and 7, except

        KEY(0xff, 2, KEY_F9),
        KEY(0xff, 4, KEY_F10),
        KEY(0xff, 5, KEY_F11),

which represent keycodes that should be emitted when entire row is
connected to the ground.  since the driver handles this case as if we
had an extra column in the key matrix. Unfortunately we do not allocate
enough space and end up owerwriting some random memory.

090830b4c7 OMAP4: clock: Fix multi-omap boot with reset un-used clocks
This patch uses "ENABLE_ON_INIT" flag on the emif clock nodes
to avoid the emif clk getting cut as part of reset un-used clock
routine which prevents boot.

Since "omap4xxx_clk_init()" calls "clk_enable_init_clocks()"
which increases the usecount on all ENABLE_ON_INIT clocks, it
prevents "omap2_clk_disable_unused()" from disabling the clock.

The real fix is to have driver for EMIF and do clock get/enable
as part of it. The EMIF driver is planned to be done HWMOD way
so till that available to keep omap3_defconfig booting on OMAP4430,
this patch is necessary.
(Will updated the auto-gen script for 44xx accordingly)

The fix was suggested by Paul Walmsley

0b96a3a3c5 OMAP3: PM: fix IO daisy chain enable to use PM_WKEN reg
Checking to se if the IO daisy chain is enabled should be checking the
PM_WKEN register, not the PM_WKST register.  Reading PM_WKST tells us
if an event occurred, not whether or not it is enabled.

Apparently, we've been lucky until now in that a pending event has not
been there during enable.  However, on 3630/Zoom3, I noticed because
of the WARN that this timeout was always happening.

4d3ae5a9a7 OMAP: hwmod: Remove IS_ERR check with omap_clk_get_by_name return value
The previous clock API was returning a standard linux error code in
case of failure. This is not the case anymore with the new
omap_clk_get_by_name API. A NULL value means that the clock node
does not exist.
Replace all the IS_ERR check by a !clk check.

682fdc96f3 OMAP: hwmod: Fix wrong pointer iteration in oh->slaves
The iteration is currently done on the omap_hwmod_ocp_if pointer
and not on the table pointer that reference them.
It worked most of the time because the structure are contiguous in
memory.

33f7ec81fb OMAP4: hwmod: Replace OCPIF_HAS_IDLEST by HWMOD_NO_IDLEST
Some initiator modules in OMAP2 & 3 does not have IDLEST bit,
in that case we cannot detect the module readiness by
polling that bit and must exist the function immediately
assuming that the module is ready.

The previous flag was affected to the OCP interface. While it is
technically true that the idlest is related to the L4 slave
interface of the module, the PRCM status belong to the module.

9a23dfe128 OMAP4: hwmod & CM: Implement the omap4_cm_wait_module_ready function
The return of the omap4_cm_wait_module_ready function is checked
in order to avoid accessing the sysconfig register if the module is
not in the correct state.
In that case the _setup will exit without trying to reset
using sysconfig.
For the moment a warning is printed. A proper management of fclk
and module reset will have to be done in order to init correctly
the problematic IPs listed below.

d9e6625c70 OMAP: CM: Move MAX_MODULE_READY_TIME to cm.h
The maximum timeout to wait for the PRCM to request that a module
exit idle or reach functionnal state is common to OMAP2/3/4 SoCs,
so, move it to the chip family-common cm.h include file.

Reduce the timeout from 20 ms to 2 ms.

2a9f5a4d45 OMAP3 clock: remove unnecessary duplicate of dpll4_m2_ck, added for 36xx
Commit 678bc9a2ea split dpll4_m2_ck,
creating a 34xx and a 36xx variant, to handle the additional 16
divider steps provided on the 36xx.  This in turn required dynamic
rewriting of the clock tree during initialization, which is
undesirable.  All this seems to be unnecessary, though, since the
additional 16 divider steps can simply be marked with RATE_IN_36XX.
This patch does so and re-merges the affected structures.

63405360fc OMAP3 clock: rename RATE_IN_343X, RATE_IN_3430ES2 to match reality
Rename the RATE_IN_343X clksel_rate.rate flag to be RATE_IN_3XXX, to reflect
that these rates are valid on all OMAP3 platforms, not just 343X.

Also rename the RATE_IN_OMAP3430ES2 clksel_rate.rate flag to be
RATE_IN_OMAP3430ES2PLUS, to reflect that these flags are valid on all
OMAP3 platforms after 3430ES2.

This patch should not result in any functional changes.

435699db6a OMAP2+ clock: clean up clkt_clksel.c
This patch cleans up arch/arm/mach-omap2/clkt_clksel.c.  It:

- makes several functions static that are not called outside the file;

- adds documentation;

- makes some code paths easier to read (hopefully), by breaking up
  compound statements and removing redundant checks;

- converts some pr_err()s that indicate clock tree data problems into WARN()s,
  so they are more likely to be noticed;

- and moves omap2_clk_round_rate() back into mach-omap2/clock.c, its proper
  home, since it is not clksel-specific.
