Subject[PATCH v2] arm, am335x: add support for the bosch shc board
Message-ID<qvJOi-2w8-15@gated-at.bofh.it>
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@denx.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:
  http://xeidos.ddns.net/buildbot/waterfall

Changes in v2:
- Use IOPAD pinmux macro as Robert Nelson
  suggested.

A different approach is being taken for resolving the issue of rtc hwmod 
on am43x epos evm [1], which is what I was attempting to solve with the 
patch you have linked. We decided to avoid changing omap_hwmod code and 
I haven't been pursuing the ti,no-init flag anymore.

Maybe I overlook something, but I cannot see, how [1] solves the RTC
hwmod problem on am335x SoC based boards. Not all boards have this problem,
so the RTC hwmod cannot be disabled for all am335x boards ...

It must be somehow configurable for boards ... I have am335x boards
which use the rtc from the SoC

gentle ping ...

No more comments on this patch? Is it Ok for mainline or are
there more issues?
