From d8f97da1b92d2fe89d51c673ecf80c4016119e5c Mon Sep 17 00:00:00 2001 From: Venkata Lakshmi Narayana Gubba Date: Tue, 18 May 2021 22:04:42 +0530 Subject: Bluetooth: hci_qca: Add support for QTI Bluetooth chip wcn6750 Added regulators,GPIOs and changes required to power on/off wcn6750. Added support for firmware download for wcn6750. Changes done in detail: 1. Added regulators and corresponding current values. 2. Added sw_ctrl GPIO pin which is output from BT SoC and indicates status of clock supply to BT SoC. 3. Added inline function to check if the SoC type is wcn6750. 4. Modified the function qca_wcn3990_init() to support wcn6750 and renamed it to qca_regulator_init().
