From 0e889a7c1b060576a5bea958280e3065b9b35cd8 Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Fri, 21 Apr 2023 20:50:41 +0300 Subject: [PATCH] arm: dts: msm: add GENI SE QUP device tree node On modern Qualcomm platforms including SDM845 a GENI SE QUP IP description is supposed to be found in board device tree nodes, the version of the IP is used by the GENI UART driver to properly set an oversampling divider value, which impacts UART baudrate. The change touches dragonboard845c and starqltechn board device tree source files, a device tree node label to "debug" UART is renamed to 'uart9' according to the naming found in Linux.
