[PATCH 1/3] platform-device driver for MQ11xx graphics chip
From: jamey
Date: Tue Aug 02 2005 - 16:14:56 EST
This patch adds platform_device driver for MQ11xx system-on-chip
graphics chip. This chip is used in several non-PCI ARM and MIPS
platforms such as the iPAQ H5550. Two subsequent patches add
support for the framebuffer and USB gadget subdevices. This patch
adds the toplevel driver to drivers/platform because it does not
provide any specific functionality (e.g., framebuffer) and it not tied
to a named physical bus. In these platforms, the MQ11xx is tied
directly to the host bus.

+ ---help---
+ MediaQ 1100/32/68/78/88 are system-on-chips that implement a
+ graphics engine, flat panel controller, USB function controller,
+ OHCI-compliant USB host controller (1132 only), I2S and SPI
+ controllers (also 1132 only).
+
+ This driver implements only the basic support for MediaQ chips;
+ after you select this option the subdevice drivers will appear
+ in the respective submenus: MediaQ 1100/32/68/78/88 framebuffer
+ support, Dell Axim X5 LCD support and so on.
+
+ To compile this driver as a module, choose M here: the
+ module will be called mq11xx_base.o.
