Dmitry Torokhov 2e65a2075c Input: RX51 keymap - fix recent compile breakage
Commit 3fea60261e ("Input: twl40300-keypad - fix handling of "all
ground" rows") broke compilation as I managed to use non-existent
keycodes.

Dmitry Torokhov 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.

Santosh Shilimkar 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

Kevin Hilman 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.

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.

Paul Walmsley 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.

Paul Walmsley 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.

Paul Walmsley d74b494971 OMAP2+ clock: remove DEFAULT_RATE clksel_rate flag
The DEFAULT_RATE clksel_rate flag is essentially useless.  It was set
on some of the lowest divisors, which, when switching to a much
higher-rate parent, could have potentially resulted in rates that
exceeded the hardware specifications for downstream clocks in the
window between the clk_set_parent(), and a subsequent clk_set_rate().
It seems much safer to just remove the flag and always use the highest
available divisor (resulting in the lowest possible rate) after the
switch, and this patch does so.

Ideally, it would be best to first attempt to switch to a divisor that
matches the clock's rate with the previous parent, if at all possible.
But that is a project for some other day or some other person.  The
parent changing code is rarely used.

Fix all of the remaining PRCM register shift/bitmask macros that did not
use the _SHIFT/_MASK suffixes to use them.  This makes the use of these
macros consistent.  It is intended to reduce error, as code can be inspected
visually by reviewers to ensure that bitshifts and bitmasks are used in
the appropriate places.
