Gregory Bean 1de238e0eb msm: add tlmm support for gpio.
GPIO support for Qualcomm SOCs requires interaction with the
radio (baseband processor). This API allows the different boards
to enable GPIO through the radio processor in a generic way.

Daniel Walker 5e96da5d50 msm: generalize clock support.
The 'PCOM' method of clock control (commands issued to the radio
CPU) is shared across several (but not all) Qualcomm SOCs.
Generalize this clock mechanism so these other SOCs can be added.

Daniel Walker 0aec66d493 arm: msm: smd: fix SMD modem processor sync condition
When booting up we need to wait for the modem processor to
partially boot. This is because the modem processor does
resource allocation for us. If we don't wait the modem won't
honor our requests and we end up crashing or in an unknown
state. This change just formalizes the waiting process.

Daniel Walker 1a86fbc167 arm: msm: smd: convert unsigned addr to unsigned long
"unsigned" translates to "unsigned int", but this value holds an
address. We always want to use unsigned long for addresses since
it will change size to fit the machine.

This just convert the one address holder to unsigned long.

Daniel Walker bf83de4037 arm: msm: smd: use either package v3 or v4 not both
This modifies SMD to use either the package v3 or package v4,
but not both. The current code tries to allocate as v4 on all
system which can produce a scary looking error message on boot up,

smem_find(16, 40): wrong size 16424
smd_alloc_channel() cid=02 size=08192 'SMD_RPCCALL'

With this error the code then falls back on the package v3 allocation
method. This method is inefficient because it causes a slow down
on some systems even when the allocation method can be determined
at compile time. It also causes a kernel size increase that effects
all system and is not needed.

This change corrects the allocation to use one method or the other
and not both.
