[ Upstream commit08846522d9] Paragraph "3.4 Power up Timing Sequence" of the AzureWave-CM256SM datasheet mentions the following about the BT_REG_ON pin, which is connected to GPIO0_C4_d: When this pin is low and WL_REG_ON is high, the BT section is in reset. Therefor set that pin to GPIO_ACTIVE_HIGH so that it can be pulled low for a reset. If set to GPIO_ACTIVE_LOW, the following errors are observed: Bluetooth: hci0: command 0x0c03 tx timeout Bluetooth: hci0: BCM: Reset failed (-110) So fix the GPIO polarity by setting it to ACTIVE_HIGH. This also matches what other devices with the same BT device have.
