14 This framework adds support for low-level control of LCD.
15 Some framebuffer devices connect to platform-specific LCD modules
16 in order to have a platform-specific way to control the flat panel
19 To have support for your specific LCD panel you will have to
25 tristate "LCD Panel support for SHARP corgi/spitz model"
48 tristate "Samsung LTV350QV LCD Panel"
51 If you have a Samsung LTV350QV LCD panel, say y to include a
52 power control driver for it. The panel starts up in power
56 The LTV350QV panel is present on all ATSTK1000 boards.
