config MFD_GLAMO bool "Smedia Glamo 336x/337x support" help This enables the core driver for the Smedia Glamo 336x/337x multi-function device. It includes irq_chip demultiplex as well as clock / power management and GPIO support. config MFD_GLAMO_FB tristate "Smedia Glamo 336x/337x framebuffer support" depends on FB && MFD_GLAMO help Frame buffer driver for the LCD controller in the Smedia Glamo 336x/337x. This driver is also available as a module ( = code which can be inserted and removed from the running kernel whenever you want). The module will be called glamofb. If you want to compile it as a module, say M here and read . If unsure, say N. config MFD_GLAMO_SPI_GPIO tristate "Glamo GPIO SPI bitbang support" depends on MFD_GLAMO help Enable a bitbanging SPI adapter driver for the Smedia Glamo. config MFD_GLAMO_SPI_FB tristate "Glamo LCM control channel SPI support" depends on MFD_GLAMO_FB help Enable a bitbanging SPI adapter driver for the Smedia Glamo LCM control channel. This SPI interface is frequently used to interconnect the LCM control interface.
