Vaibhav Hiremath 886aba558b greybus: arche-platform: Export fn to allow timesync driver to change the state ... With the addition of the timesync driver and looking at the hardware interfaces we have, its clear we need to add a new arche-platform state. This patch adds ARCHE_PLATFORM_STATE_TIME_SYNC to the arche-platform driver to facilitate transition to the TIME_SYNC state if-and-only-if the arche-platform driver is in the ACTIVE state. This is mainly needed as wake/detect lines are shared between TIMESYNC operation and basic control functionality of APBs. So during TIMESYNC we want to make sure that the events on wake/detect lines are ignored by the arche-platform APB reset logic. This patch adds one exported function, which can be invoked from timesync driver code, allowing, switching between ARCHE_PLATFORM_STATE_TIME_SYNC <=> ARCHE_PLATFORM_STATE_ACTIVE states.
