Subject: [PATCH v1] Bluetooth: hci_qca: Add qca_power_on() API to support both wcn399x and Rome power up
Date: Tue, 7 Jan 2020 13:26:01 +0800 [thread overview]
Message-ID: <20200107052601.32216-1-rjliao@codeaurora.org> (raw)
This patch adds a unified API qca_power_on() to support both wcn399x and
Rome power on. For wcn399x it calls the qca_wcn3990_init() to init the
regulators, and for Rome it pulls up the bt_en GPIO to power up the btsoc.
