Subject: [PATCH] ARM: dts: msm: Adjust Squelch Repeater Register on SUN mtp
 platform
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update the TUNE_USB2_SQUELCH_U register (0xFD54) to a value of 0x4 in
the MTP platform’s override sequence. This adjustment addresses the
current issue of excessive RX sensitivity, which causes the device to
misinterpret noise as valid high-speed USB signals, leading to frequent
USB disconnections.

By increasing the squelch level, we enhance the precision of USB signal
detection, reducing false positives and improving overall USB stability.
