From 1c65b6184441bdbdab2fae2984354f2038b8b6f7 Mon Sep 17 00:00:00 2001 From: Jonathan Bakker Date: Sat, 13 Jun 2020 11:44:27 -0700 Subject: [PATCH] ARM: dts: s5pv210: Correct BCM4329 bluetooth node There are several issues with the bluetooth node - the wrong compatible was used (because the bcm4329 compatible didn't exist when the node was added), the max rate was incorrect (due to limitations in the samsung TTY driver which have now been fixed), the clocks were not assigned properly so some rates didn't work, and the some pinctrl settings weren't explicitly set. Fix all of the above issues. While we're at it, update from the deprecated host-wakeup-gpios property to the host-wake interrupt.
