Subject: [PATCH 2/2] Bluetooth: qca: run the power-on/off sequence for QCA6390 too
Date: Tue,  5 Dec 2023 12:09:03 +0100	[thread overview]
Message-ID: <20231205110903.68898-2-brgl@bgdev.pl> (raw)
In-Reply-To: <20231205110903.68898-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

The Bluetooth module on QCA6390 needs to be powered-on by enabling the
relevant regulators and driving the enable GPIO high. We can reuse the
power sequence for the WNC models.
