Subject: [PATCH V3 0/2] add support for pmic_arb v2 and correct framework
Date: Mon,  9 Feb 2015 15:51:10 -0700	[thread overview]
Message-ID: <1423522272-24472-1-git-send-email-gavidov@codeaurora.org> (raw)

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.

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