Subject: [PATCH 13/13] ARM: lpc32xx: remove platform data of ARM PL111 LCD controller
Date: Tue, 29 Jan 2019 21:20:49 +0200	[thread overview]
Message-ID: <20190129192049.11223-14-vz@mleia.com> (raw)
In-Reply-To: <20190129192049.11223-1-vz@mleia.com>

The auxilary platform data added for the LCD controller is not needed
anymore, because the controller and a connected panel are properly
described in Phytec phyCORE-LPC3250 board dts file.
