This driver supports the Qualcomm PNP clkdiv peripheral. It
allowed for configuring divide factors for various clock outputs
on the PMIC. The source clock is CXO.
The driver allows for configuration of the clkdiv device through
Device Tree. Some optional parameters may be specified instead at
runtime with the qpnp_clkdiv_config() API.

The PON module supports various reset sources (physical pins)
such as KPDPWR, RESIN, RESIN+KPDPWR. These pins can be configured
for different reset types (such as warm, soft, hard) and can also
be used as push buttons (keys).
In the push-button configuration these pins act as gpios, only
reporting the state on the line (high/low) and no additional
pon based configuration being done in the hardware or software.
They can be used for generic buttons (such as volume up/down,
directional keys)

The gpio driver was not a true platform driver and hence wasn't
supported by device tree. This patch fixes that for non-DT targets
by making sure the device gets added early on during board init.
For DT-targets, adding the gpio-controller property for the device
makes sure the msmgpio device gets probed.
This change is done for all TLMM_v2 targets (msm8660 and future)
TLMM_V1 targets remain unaffected.

The qcom,msm-id entry specifies the MSM chipset, platform and
hardware revision. This is used by the Android dtbtool utility
to generate a table of device tree used in the boot.img.
The qcom,msm-id syntax is:
qcom,msm-id = <chipset_id, platform_id, rev_id> [, <...>];
The entry can optionally be an array with variable number of
triplets indicating the device tree supports more than one
chipset/platform/hardware rev.
Note that the id's are hardware ID's reported by the hardware
and not commonly used literal ID's. E.g. MSM8974's chipset ID
is 126, not 8974.
