This is a driver chip for 240x160 4-bit greyscale LCDs.
It is capable of 4-wire (8 bit) or 3-wire (9 bit) SPI that have both been
tested. (It also has a 6800 or 8080-style parallel interface, but I have
not included support for it.)

diff --git a/drivers/staging/fbtft/fb_uc1611.c b/drivers/staging/fbtft/fb_uc1611.c

+static int init_display(struct fbtft_par *par)
+{
+	int ret;
+
+	fbtft_par_dbg(DEBUG_INIT_DISPLAY, par, "%s()\n", __func__);
+
+	/* Set CS active high */
+	par->spi->mode |= SPI_CS_HIGH;

Why is this set here and not in fbtft_device along side SPI_MODE_3?

+static int set_var(struct fbtft_par *par)
+{
+	fbtft_par_dbg(DEBUG_INIT_DISPLAY, par, "%s()\n", __func__);
+
+	/* par->info->fix.visual = FB_VISUAL_PSEUDOCOLOR; */

This comment can be removed I guess.
