From 8496272d8116295053139a5d309d59694902f043 Mon Sep 17 00:00:00 2001 From: Horia Geantă Date: Fri, 17 Mar 2017 12:05:58 +0200 Subject: soc/qman: export non-programmable FQD fields query MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Export qman_query_fq_np() function and related structures. This will be needed in the caam/qi driver, where "queue empty" condition will be decided based on the frm_cnt.
