Subject: [PATCH 1/6] ath10k: use clean packet headers
Date: Tue,  9 Apr 2019 21:08:46 +0200	[thread overview]
Message-ID: <20190409190851.4557-2-erik.stromdahl@gmail.com> (raw)
In-Reply-To: <20190409190851.4557-1-erik.stromdahl@gmail.com>

From: Alagu Sankar <alagusankar@silex-india.com>

HTC header carries junk values that may be interpreted by the firmware
differently. Enable credit update only if flow control is enabled for
the corresponding endpoint.

PLL clock setting sequence does not mask the PLL_CONTROL
register value. Side effect of not masking the values is not known as
the entire pll clock setting sequence is undocumented.
