Subject[PATCH 2/5] ARM: at91/neocore926: fix LCD-wiring mode
Date
From: Johan Hovold <jhovold@gmail.com>

Fix regression introduced by commit 787f9fd23283 ("atmel_lcdfb: support
16bit BGR:565 mode, remove unsupported 15bit modes") which broke 16-bpp
modes for older SOCs which use IBGR:555 (msb is intensity) rather than
BGR:565.

The above commit also removed the RGB:555-wiring hack without fixing the
neocore926 board which used it. Fix by specifying RGB-wiring and let the
driver handle the final SOC-dependant layout.

Remove the no longer used ATMEL_LCDC_WIRING_RGB555 define.

Compile-only tested.
