From e3396b8bddd2ea822f9390f1ba49c22d769a7534 Mon Sep 17 00:00:00 2001 From: Carl Huang Date: Mon, 17 Aug 2020 13:31:47 +0300 Subject: [PATCH] ath11k: ce: support different CE configurations QCA6390 uses only 9 Copy Engines while IPQ8074 may use 12, make it possible to change CE configuration dynamically via hw_params. The defines for host_ce_config_wlan and CE_COUNT are temporary solutions, they will be removed in the following patches to keep things simple.
