From 9a5a668dc348f98de464114411421c4e9381cf21 Mon Sep 17 00:00:00 2001 From: Giovanni Cabiddu Date: Thu, 30 Jul 2020 13:27:42 +0100 Subject: crypto: qat - add delay before polling mailbox The mailbox CSR register has a write latency and requires a delay before being read. This patch replaces readl_poll_timeout with read_poll_timeout that allows to sleep before read. The initial sleep was removed when the mailbox poll loop was replaced with readl_poll_timeout.
