Ach, should have remembered that :-( Indeed there is an LCDC hwmod:
static struct omap_hwmod am33xx_lcdc_hwmod = {
.name = "lcdc",
.class = &am33xx_lcdc_hwmod_class,
.clkdm_name = "lcdc_clkdm",
.mpu_irqs = am33xx_lcdc_irqs,
.flags = HWMOD_SWSUP_SIDLE | HWMOD_SWSUP_MSTANDBY,
.main_clk = "lcd_gclk",
.prcm = {
.omap4 = {
.clkctrl_offs = AM33XX_CM_PER_LCDC_CLKCTRL_OFFSET,
.modulemode = MODULEMODE_SWCTRL,
},
},
};

Indeed.
