Mehnert 1dde9f75b6 iomux-mx25.h slew rate adjusted for LCD __LD pins
For some reason (sadly i don't identifying the patch right now)
two LCD data lines configured PAD_CTL_SRE_SLOW (wrong slew rate)
since Kernel 3.1. MX25_PAD_GPIO_E__LD16 and MX25_PAD_GPIO_F__LD17
This results in an fauly behaviour and strange color effects.

To ensure that all LCD data pins configured with the proper slew rate,
this patch changes to IOMUX define of all LCD __LDxx pins to PAD_CTL_SRE_FAST.

This problem may affect other mx25 platforms like mx25pdk. Sadly i can't test
it. Of course this problem shouldn't occur when you done your LCD muxing
correctly in the bootloader.

Best regards,
Torsten

Uwe Kleine-König 30c766bdec ARM: davinci: DA850: move da850_register_pm to .init.text
All callers (board-mityomapl138.c and board-da850-evm.c) use it in
__init functions only.

This fixes:

	WARNING: vmlinux.o(.text+0xd664): Section mismatch in reference from the function da850_register_pm() to the function .init.text:da8xx_get_mem_ctlr()
	The function da850_register_pm() references
	the function __init da8xx_get_mem_ctlr().
	This is often because da850_register_pm lacks a __init
	annotation or the annotation of da8xx_get_mem_ctlr is wrong.

Linus Torvalds 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.

When a CPU is taken out of reset, either cold booted or hotplugged in,
some of its PMU registers can contain UNKNOWN values.

This patch adds a hotplug notifier to ARM core perf code so that upon
CPU restart the PMU unit is reset and becomes ready to use again.

When disabling a counter on an ARMv7 PMU, we should also clear the

This prevents a spurious overflow being picked up later and leading to

Will Deacon 5727347180 ARM: 7354/1: perf: limit sample_period to half max_period in non-sampling mode
On ARM, the PMU does not stop counting after an overflow and therefore
IRQ latency affects the new counter value read by the kernel. This is
significant for non-sampling runs where it is possible for the new value
to overtake the previous one, causing the delta to be out by up to
max_period events.

Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due
to IRQ latency") attempted to fix this problem by allowing interrupt
handlers to pass an overflow flag to the event update function, causing
the overflow calculation to assume that the counter passed through zero
when going from prev to new. Unfortunately, this doesn't work when
overflow occurs on the perf_task_tick path because we have the flag
cleared and end up computing a large negative delta.

This patch removes the overflow flag from armpmu_event_update and
instead limits the sample_period to half of the max_period for
non-sampling profiling runs.

Yuan Jiangli 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

WARNING: arch/arm/mach-omap2/built-in.o(.text+0x183c): Section mismatch in reference from the function omap2_init_processor_devices() to the function .init.text:_init_omap_device()
The function omap2_init_processor_devices() references

This is often because omap2_init_processor_devices lacks a __init

Failure is reported on hx4700 with kernel v3.3-rc1.

__mfp_validate: GPIO20 is invalid pin
__mfp_validate: GPIO21 is invalid pin
__mfp_validate: GPIO15 is invalid pin
__mfp_validate: GPIO78 is invalid pin
__mfp_validate: GPIO79 is invalid pin

__mfp_validate: GPIO33 is invalid pin
__mfp_validate: GPIO48 is invalid pin
__mfp_validate: GPIO49 is invalid pin
__mfp_validate: GPIO50 is invalid pin

Since pxa_last_gpio is used in mfp-pxa2xx driver. But it's only
updated in pxa-gpio driver that run after mfp-pxa2xx driver.

So update the pxa_last_gpio first in mfp-pxa2xx driver.

Save the contexts and loss count when timer is stopped.
