Now that __cpuinit has been removed, the __ref markings on these
functions are useless. Remove them. This also reduces the size of

presumably because now we don't have to jump to code in the
.ref.text section and/or the noinline marking is removed.

The z2 machine calls pxa27x_set_pwrmode() in order to power off
the machine, but this function gets discarded early at boot because
it is marked __init, as pointed out by kbuild:
WARNING: vmlinux.o(.text+0x145c4): Section mismatch in reference from the function z2_power_off() to the function .init.text:pxa27x_set_pwrmode()
The function z2_power_off() references
the function __init pxa27x_set_pwrmode().
This is often because z2_power_off lacks a __init
annotation or the annotation of pxa27x_set_pwrmode is wrong.
This removes the __init section modifier to fix rebooting and the
build error.

[tony@atomide.com: reworked the soc.h changes to minimum]
Signed-off-by: Tony Lindgren <tony@atomide.com>
The naming for the cpu_is macros is confusing as the CPU is separate
and within the SoC. Let's rename all the macros to soc_is, and let's
define cpu_is also for the ones still in use. Then we can just remove
the cpu_is macros once the users are fixed up.
To keep the chances of breaking anything, the changes were
generated with the following regular expressions:
s/cpu_is/soc_is/g
s/CPU/SoC/g
Then the list of existing cpu_is users was generated with:
$ $ grep -o -e 'cpu_is_.\+()' arch/arm/mach-omap2/*.[chS] | \
cut -d: -f2 | sort | uniq
And added to the end of the soc.h.
I decided to rework the earlier patches by Keerthy <j-keerthy@ti.com>
to keep changes down to minimum to avoid potential errors and stick
to just search and replace.

as it turns out, __omap_gptimer_init() and
__omap_sync32k_timer_init() are essentially
the same thing, but __omap_gptimer_init() wants

Instead of forcing all those devices to pass
a use_gptimer cmdline argument, we add a new
function argument to __omap_sync32k_timer_init()
in preparation to deleting __omap_gptimer_init().
On a follow-up patch, we will remove uses of
__omap_gptimer_init() and replace them with
__omap_sync32k_timer_init() and pass the last
argument as true.

Merge "Clean-up for omaps for v4.4 merge window" from Tony Lindgren:
- Remove legacy omap3 ISP code as the driver is DT only
- Remove VoiceBlue board support as it's been unused over
10 years now
- Remove unused polarity control macros for TWL
- Remove two unneeded semicolons
- Remove unused core dpll code for reprogramming the rates
Note that this branch is against v4.3-rc4 as that contains critical
MMC related fixes to boot with MMC working on most omaps.

HTC Magician contains a MAX1587A voltage regulator for a Vcore supply.
The Vcore regulation is required for a CPU speed switching. This patch adds
declaration for the max1586 driver.
Notice:
- MAX1587A version does not support the V6 (USIM) output.
- A boost resistor was directly measured for a board_id 0x3a.

Old definition for the physmap-flash driver is incomplete:

This patch changes fast_mode settings for the normal and power I2C
controller on the HTC Magician machine.
Connected device on the Power I2C:
- MAX1587A: working in the fast mode
Connected devices on the Normal I2C:
- UDA1380: working in the fast mode
- OV9640: bus became stuck in the fast mode
The OV9640 is not using a standard I2C protocol, but an SCCB variant. Maybe
it is not fully compatible in the fast mode. Therefore fast mode for normal
I2C is disabled. If you not using the OV9640 then you can enable the fast
mode for the UDA1380.

This patch renames EGPIOs, which are used for the charging cable presence
and type detection. Old names did not correspond with an observed
functionality (on board_id 0x3a). The behavior is not:
- AC charger
- USB charger
- Cable detection
, but:
- AC/USB type
- Cable detection1
- Cable detection2
This patch fixes a possible typo in the bit offset for the cable detection
EGPIO declaration, too.
