      ARM: dts: keystone-k2g-evm: fix rgmii phy-mode for ksz9031 phy · fe1d899f
      Grygorii Strashko authored 
      Since commit bcf3440c ("net: phy: micrel: add phy-mode support for the
KSZ9031 PHY") the networking is broken on keystone-k2g-evm board.

The above board have phy-mode = "rgmii-id" and it is worked before because
KSZ9031 PHY started with default RGMII internal delays configuration (TX
off, RX on 1.2 ns) and MAC provided TX delay by default.
After above commit, the KSZ9031 PHY starts handling phy mode properly and
enables both RX and TX delays, as result networking is become broken.

Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous
behavior.

      ARM: dts: imx6qdl-icore: Fix OTG_ID pin and sdcard detect · 4a601da9
      Michael Trimarchi authored 
      The current pin muxing scheme muxes GPIO_1 pad for USB_OTG_ID
because of which when card is inserted, usb otg is enumerated
and the card is never detected.

      ARM: imx: Remove imx_add_imx_dma() unused irq_err argument · f8951dce
      Bjorn Helgaas authored 
      No callers of imx_add_imx_dma() need an error IRQ, so they supply 0 as
"irq_err", which means we register a resource of IRQ 0, which is invalid
and causes a warning if used.

Remove the "irq_err" argument altogether so there's no chance of trying to
use the invalid IRQ 0.

As it turns out, mxc_register_gpio() is a bit lax when setting the
number of resources: it registers a resource with interrupt 0 when in
reality there is no such interrupt. Fix the problem by not declaring
the second interrupt resource if there is no second interrupt.
