Subject: [PATCH edk2-platforms v2 6/7] Platform/NinetySixBoards: add core driver for LS connector and config
Date: Tue, 20 Feb 2018 17:49:43 +0000	[thread overview]
Message-ID: <20180220174944.525-7-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20180220174944.525-1-ard.biesheuvel@linaro.org>

This adds a driver that manages the 96boards LS connector, i.e, it
installs a HII page to configure the type of mezzanine that is installed
in the slot, and it exposes this information via the LS connector protocol.
It is also in charge of applying the overlay to the platform device tree
at end of DXE.
