      ARM: dts: OMAP4: Fix ethernet IRQ for OMAP4 boards · e60f18d6
      Jon Hunter authored 
      

Commit ff5c9059 (ARM: dts: OMAP3+: Correct gpio #interrupts-cells
property) updated the number of interrupt cells required for configuring
gpios as interrupts for other devices (such as ethernet controllers).
This update allowed the interrupt type (edge, level, etc) to be
configured via device-tree (as described in the
Documentation/devicetree/bindings/gpio/gpio-omap.txt).

This broke ethernet support on the OMAP4 SDP board that defines a gpio
as the ethernet IRQ because the interrupt type (level, edge, etc) was
not getting configured correctly. This board use the ks8851 ethernet
chip which has an active low interrupt. Fix this by defining the gpio
interrupt as active-low in the device-tree binding.

Please note that the OMAP4-VAR-SOM also uses the same ethernet
controller and it is expected it will have the same problem. So the
same fix is also applied to this board.

      ARM: dts: add mshc controller node for Exynos4x12 SoCs · 662478d0
      Thomas Abraham authored 
      

Commit 800974ac ("ARM: dts: Add board dts file for ODROID-X") includes a node
to describe the board level properties for mshc controller. But the mshc
controller node was not added in the Exynos4x12 dtsi file which resulted
in the following warning when compiling the dtb files.

Warning (reg_format): "reg" property in /mshc@12550000/slot@0 has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)
Warning (avoid_default_addr_size): Relying on default #address-cells value for /mshc@12550000/slot@0
Warning (avoid_default_addr_size): Relying on default #size-cells value for /mshc@12550000/slot@0

Fix this by adding the mshc controller node for Exynos4x12 SoCs.

      ARM: dts: Disable the RTC by default on exynos5 · 522ccdb6
      Doug Anderson authored 
      

This change makes the rtc on the exynos5250 and 5440 disabled by
default to match exynos4.

Ever since the common clock framework came in, exynos5250 boards
have dumped lots of warnings in the boot log. It turns out that
we don't see those on exynos4 since the rtc is disabled by default.
While we need to get to the bottom of the problems with the RTC,
it still makes sense to have the default state of the RTC on exynos
boards match.

For the record, warnings look like this:
