Subject: [PATCH AUTOSEL 6.5 02/18] ARM: dts: ti: omap: Fix noisy serial with overrun-throttle-ms for mapphone
Date: Sat, 7 Oct 2023 20:48:36 -0400 [thread overview]
Message-ID: <20231008004853.3767621-2-sashal@kernel.org> (raw)
In-Reply-To: <20231008004853.3767621-1-sashal@kernel.org>
From: Tony Lindgren <tony@atomide.com>
[ Upstream commit 5ad37b5e30433afa7a5513e3eb61f69fa0976785 ]
On mapphone devices we may get lots of noise on the micro-USB port in debug
uart mode until the phy-cpcap-usb driver probes. Let's limit the noise by
using overrun-throttle-ms.
Note that there is also a related separate issue where the charger cable
connected may cause random sysrq requests until phy-cpcap-usb probes that
still remains.
