Subject: [PATCH] arm, am335x: add support for the bosch shc board

add support for the am335x based shc board.

UART: 0-2 and 4
DRAM: 512 MiB
MMC:  OMAP SD/MMC: 0 @ 26 MHz
      OMAP SD/MMC: 1 @ 26 MHz
I2C:  at24 eeprom, pcf8563
USB:  USB1 (host)

Signed-off-by: Heiko Schocher <hs@...x.de>
---
The following patches are needed to get all working
for the shc board:
- disable clkout on pcf8563
  accepted.
  http://www.spinics.net/lists/devicetree/msg98542.html

- leds: leds-gpio: add shutdown function
  accepted.
  https://lkml.org/lkml/2015/10/13/169

- net: phy: smsc: disable energy detect mode
  accepted
  [PATCH v2 2/2] net: phy: smsc: disable energy detect mode
  https://lkml.org/lkml/2015/10/17/2
  [PATCH v2 1/2] drivers: net: cpsw: add phy-handle parsing
  https://lkml.org/lkml/2015/10/17/4

- ARM: OMAP2+: omap_hwmod: Introduce ti,no-init dt property
  http://lists.infradead.org/pipermail/linux-arm-kernel/2015-March/328204.html
  @Dave: What is the current state of this patch?
  I have the same problem here on this am335x based board

- [PATCH v2] regulator: tps65217: remove tps65217.dtsi file
  http://www.kernelhub.org/?msg=868907&p=2

- bootlog and automated tests:
