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.
