Overwiew +----------- +The SH7760/SH7763 have an integrated LCD Display controller (LCDC) which +supports (in theory) resolutions ranging from 1x1 to 1024x1024, +with color depths ranging from 1 to 16 bits, on STN, DSTN and TFT Panels. + +Caveats: +* Framebuffer memory must be a large chunk allocated at the top + of Area3 (HW requirement).

CRT may not display properly for DuoView CRT & DVI display at + the "640x480" PAL mode with DVI overscan enabled. + 2. SAMM stands for single adapter multi monitors. It is different from + multi-head since SAMM support multi monitor at driver layers, thus fbcon + layer doesn't even know about it; SAMM's second screen doesn't have a + device node file, thus a user mode application can't access it directly. + When SAMM is enabled, viafb_mode and viafb_mode1, viafb_bpp and + viafb_bpp1, viafb_refresh and viafb_refresh1 can be different. + 3. When console is depending on viafbinfo1, dynamically change resolution + and bpp, need to call VIAFB specified ioctl interface VIAFB_SET_DEVICE + instead of calling common ioctl function FBIOPUT_VSCREENINFO since + viafb doesn't support multi-head well, or it will cause screen crush. + 4. VX800 2D accelerator hasn't been supported in this driver yet.
