Subject: [PATCH v2 1/2] Bluetooth: hci_qca: Added support for wcn3998
Date: Fri,  8 Mar 2019 18:17:38 +0530	[thread overview]
Message-ID: <1552049259-25429-2-git-send-email-c-hbandi@codeaurora.org> (raw)
In-Reply-To: <1552049259-25429-1-git-send-email-c-hbandi@codeaurora.org>

Added new compatible for wcn3998 and corresponding voltage
and current values to wcn3998 compatible.
Changed driver code to support wcn3998

Signed-off-by: Harish Bandi <c-hbandi@codeaurora.org>
