Both fb and mmc will need operable clock control to function. mmc will also need the vreg code (to adjust power to the sdcard slot). Both clk_* and vreg_* are already in, though I haven't put them through their paces in the latest kernel tree. They both just wrap proc_comm (as the modem owns both clock and power control) and are pretty simple -- they should "just work". The framebuffer is "fun" to bootstrap -- it needs the mddi transport (serial video interface), mddi-to-lcdc bridge and panel init code, and the mdp dma code to go. Brian
