From 08e7938665708c64bd1cc886a0bcc0f9653cf589 Mon Sep 17 00:00:00 2001 From: Diederik de Haas Date: Tue, 8 Oct 2024 13:15:39 +0200 Subject: [PATCH] arm64: dts: rockchip: Fix reset-gpios property on brcm BT nodes [ Upstream commit 2b6a3f857550e52b1cd4872ebb13cb3e3cf12f5f ] For most compatibles, the "brcm,bluetooth.yaml" binding doesn't allow the 'reset-gpios' property, but there is a 'shutdown-gpios' property. Page 12 of the AzureWave-CM256SM datasheet (v1.9) has the following wrt pin 34 'BT_REG_ON' (connected to GPIO0_C4_d on the PineNote): Used by PMU to power up or power down the internal regulators used by the Bluetooth section. Also, when deasserted, this pin holds the Bluetooth section in reset. This pin has an internal 200k ohm pull down resistor that is enabled by default. So it is safe to replace 'reset-gpios' with 'shutdown-gpios'.
