| Message-ID | <sIlqp-5qf-5@gated-at.bofh.it> |
GPIO7 is configured in POWERHOLD mode which has higher priority over DEV_ON bit and keeps the PMIC supplies on even after the DEV_ON bit is turned off. This property enables driver to over ride the POWERHOLD value to GPIO7 so as to turn off the PMIC in power off scenarios. Signed-off-by: Keerthy <j-keerthy@ti.com> Acked-by: Rob Herring <robh@kernel.org> --- Remaining patches of the series are already queued. Changes in v3: Added Rob's Ack.
