OMAP4 has module specific context lost registers which makes it now possible to have module level context loss count, instead of relying on the powerdomain level context count. Add 2 private hwmod api's to update/clear the hwmod/module specific context lost counters/register. Update the module specific context_lost_counter and clear the hardware bits just after enabling the module. omap_hwmod_get_context_loss_count() now returns the hwmod context loss count them on platforms where they exist (OMAP4), else fall back on the pwrdm level counters for older platforms. Signed-off-by: Rajendra Nayak <rnayak@ti.com> [paul@pwsan.com: added function kerneldoc, fixed structure kerneldoc, rearranged structure to avoid memory waste, marked fns as OMAP4-specific, prevent fn entry on non-OMAP4 chips, reduced indentation, merged update and clear, merged patches] [t-kristo@ti.com: added support for arch specific hwmod ops, and changed the no context offset indicator to USHRT_MAX] Signed-off-by: Tero Kristo <t-kristo@ti.com> [paul@pwsan.com: use NO_CONTEXT_LOSS_BIT flag rather than USHRT_MAX; convert unsigned context lost counter to int to match the return type; get rid of hwmod_ops in favor of the existing soc_ops mechanism; move context loss low-level accesses to the PRM code] Signed-off-by: Paul Walmsley <paul@pwsan.com>
