From 7de05cb47134a3ac179f28f5363c36d9ac17c6c3 Mon Sep 17 00:00:00 2001 From: Neeraj Sanjay Kale Date: Fri, 11 Aug 2023 15:42:31 +0530 Subject: Bluetooth: btnxpuart: Remove check for CTS low after FW download This removes the unnecessary check for CTS low after FW download. After FW download is complete, the CTS line is already seen low. It becomes high after 2 msec, and low again after FW initialization is complete. This makes the current check for CTS low redundant. This removes the wait for CTS low section and increase delay to 1200msec instead, which is sufficiant for all NXP chipsets to initialize FW.
