Subject: [RESEND PATCH v2 3/3] Bluetooth: qca: run the power-on/off sequence for QCA6390 too
Date: Fri, 8 Dec 2023 10:09:36 +0100 [thread overview]
Message-ID: <20231208090936.27769-4-brgl@bgdev.pl> (raw)
In-Reply-To: <20231208090936.27769-1-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 if we add the list of required
regulators to the OF match data.
