Subject: [PATCH V5 0/2] add support for pmic_arb v2 and correct framework

pmic_arb v2 has no support for spmi non-data commands and thus
returns -EOPNOTSUPP on .cmd callback. This causes a failure in
spmi_drv_probe() which sends a wakeup command to the slave before
probing its driver. This patchset removes the wakeup from
spmi_drv_probe() since the spmi spec stipulates that a slaves
default state is active and doesn't need a wakeup.

Changes from v3 to v4:
* Remove the claim that this is a bug fix off the commit text
* Unmap the core register space as soon as we know that it will not be used
* Assign the core reg space to a local until we know if it appropriate to use
   it to configure the controller fields (on v1) or unmap it (on v2).

Changes from v4 to v5:
* remove the unmap added in v4 since it is used again and the mapping is managed.
* correct printf formatting for 64bit compilers.
* correct base address for reading the channel table.

Gilad Avidov (2):
  spmi: remove wakeup command before slave probe
  spmi: pmic_arb: add support for hw version 2
