ARM: add infra-structure for BCM2835 and Raspberry Pi The BCM2835 is an ARM SoC from Broadcom. This patch adds very basic support for this SoC. http://www.broadcom.com/products/BCM2835 http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf Note that the documentation in the latter .pdf assumes the MMU setup that's used on the "VideoCore" companion processor, and does not document physical peripheral addresses. Subtract 0x5e000000 to obtain the physical addresses. This is accounted for by the ranges property in the /soc node in the device tree. The BCM2835 SoC is used in the Raspberry Pi. This patch also adds a minimal device tree for this board; enough to see some very early kernel boot messages through earlyprintk. However, this patch does not yet provide a useful booting system. http://www.raspberrypi.org/. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split from 3-4 months ago, and significantly stripped down and modified since.

#include "bcm2835-rpi.dtsi"
ARM: bcm2835: dt: Add the ethernet to the device trees The hub and the ethernet in its port 1 are hardwired on the board. Compared to the adapters that can be plugged into the USB ports, this one has no serial EEPROM to store its MAC. Nevertheless, the Raspberry Pi has the MAC address for this adapter in its ROM, accessible from its firmware. U-Boot can read out the address and set the local-mac-address property of the node with "ethernet" alias. Let's add the node so that U-Boot can do its business. Model B rev2 and Model B+ entries were verified by me, the hierarchy and pid/vid pair for the Version 2 was provided by Peter Chen. Original Model B is a blind shot, though very likely correct.

ARM: dts: bcm283x: Add dtsi for USB host mode In case dr_mode isn't passed via DT, the dwc2 defaults to OTG mode. But all Raspberry Pi boards here are designed only for host mode. So fix this issue by providing a dtsi file which set the dr_mode to host.

ARM: bcm2835: Add Raspberry Pi's ACT LED to DT The Raspberry Pi board has one GPIO-controlled LED labeled "ACT". Add it to the DT via the gpio-leds driver, so users can control it from userspace. If CONFIG_LEDS_TRIGGER_HEARTBEAT is set, the LED will also signal some sign of life. The GPIO circuitry is low-active. And as the bootloader may decide to switch the LED on at boot time, the default state is 'keep'. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
