0cacaf51a0 IOMMU fixes for Linux v3.3-rc6
Two fixes are queued up. The first is an additional fix for the OMAP
 initialization order issue and the second patch fixes a possible section
 mismatch which can lead to a kernel crash in the AMD IOMMU driver when
 suspend/resume is used and the compiler has not inlined the
 iommu_set_device_table function.

3223d007a3 ARM: OMAP3+: PM: VP: fix integer truncation error
commit 2f34ce81b8
(OMAP3: PM: Adding voltage driver support.)
introduced runtime computation of waittime to handle all potential
sys clocks available.

In the voltage processor, the SPMSUpdateWait is calculated based on
the slew rate and the voltage step (SMPSUpdateWait = slew rate *
Voltage Step). After the voltage processor receives the SMPS_Ack
signal, the Voltage Controller will wait for SMPSUpdateWait clock
cycles for the voltage to settle to the new value. For all
practical purposes, the waittime parameter is the OMAP hardware
translation of what the slew rate on the PMIC is.

As an example, with TPS62361 on OMAP4460,
step_size = 10000
slew_rate = 32000
sys_clk_rate = 38400

Our current computation results in the following:
 = ((step_size / slew_rate) * sys_clk_rate) / 1000
 = ((10000 / 32000) * 38400 / 1000
 = 0

Fix the same using DIV_ROUND_UP as an extra wait clock cycle
is better than lesser clock cycle. For the above example, this
translates to:
 = (10000 * 38400) / (1000 * 32000)
 = 12

When CONFIG_HOTPLUG_CPU=n, there are unused functions in wakeupgen:

It is called by an __init function and calls only __init functions, so
it should also be init.

Note: cpu_is_34xx() is true for am33xx also. Doing

d867093d41 ARM: OMAP2+: Remove apply_uV constraints for fixed regulator
VUSB is a fixed regulator, so get rid of the apply_uV constraint
for it, which fixes the following error seen at boot on omap4
SDP and PANDA boards.

d82ba9954b OMAP4: dma: Correct CPU version check for dma_common_ch_end
CCDN is the last common channel register in all OMAP4 versions. Use
cpu_is_omap44xx() instead of the cpu_is_omap4430().
cpu_is_omap4430() returns 0 unconditionally. This causes that the
dma_common_ch_end register variable is not configured correctly on OMAP4, not
even for OMAP4430.
Because of this, registers between CCFN - CCDN will be not cleard in the
omap2_clear_dma function in OMAP4.

d5a74afd08 IOMMU fixes for Linux 3.3-rc5
All the fixes are for the OMAP IOMMU driver. The first patch is the
 biggest one. It fixes the calls of the function omap_find_iovm_area() in
 the omap-iommu-debug module which expects a 'struct device' parameter
 since commit fabdbca instead of an omap_iommu handle. The
 omap-iommu-debug code still passed the handle to the function which
 caused a crash.
 The second patch fixes a NULL pointer dereference in the OMAP code and
 the third patch makes sure that the omap-iommu is initialized before the
 omap-isp driver, which relies on the iommu. The last patch is only a
 workaround until defered probing is implemented.

8930b4e (ARM: omap: fix section mismatch warnings in mux.c caused by hsmmc.c)

Fix this by changing arch/arm/Makefile to build mach-omap2 based on

allow randconfig to generate buildable .config files.

Note that we can also remove few uncecssary ARCH_OMAP2PLUS lines

During kernel init, we reset all IP blocks on the OMAP that we can,
even if there is no driver compiled for that IP block.  Unlike most IP
blocks, the I2C block requires some extra programming for this to
work.  This reset code is incorrectly omitted when the I2C driver is
deselected.  In this circumstance, the build breaks.  Fix by compiling
the I2C reset code unconditionally.

3b972bf06c ARM: OMAP2+: Split omap2_hsmmc_init() to properly support I2C GPIO pins
Otherwise omap_device_build() and omap_mux related functions
can't be marked as __init when twl is build as a module.

If a board is using GPIO pins or regulators configured by an
external chip, such as TWL PMIC on I2C bus, the board must
mark those MMC controllers as deferred. Additionally both
omap_hsmmc_init() and omap_hsmmc_late_init() must be called
by the board.

For MMC controllers using internal GPIO pins for card
detect and regulators the slots don't need to be marked
deferred. In this case calling omap_hsmmc_init() is sufficient.

Only mark the MMC slots using gpio_cd or gpio_wd as deferred
as noted by Igor Grinberg <grinberg@compulab.co.il>.

Note that this patch does not change the behaviour for
board-4430sdp.c board-omap4panda.c. These boards wrongly
rely on the omap_hsmmc.c init function callback to configure
the PMIC GPIO interrupt lines on external chip. If the PMIC
interrupt lines are not configured during init, they will
fail.
