linux-next: manual merge of the rtc tree with the arm-soc tree

[Stephen Rothwell]

Hi Alexandre,

Today's linux-next merge of the rtc tree got a conflict in:

  arch/arm/boot/dts/am437x-gp-evm.dts

between commits:

  d3d92af19e99 ("ARM: dts: am437x-gp-evm: McASP1 node for audio support")
  cf9a4850e995 ("ARM: dts: am437x-gp-evm: Enable analog audio via simple-card")

from the arm-soc tree and commit:

  f7331bad0fa4 ("ARM: dts: AM437x: Add the internal and external clock nodes for rtc")

from the rtc tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

It is just a matter of taste but maybe both oscillators/clocks can be
grouped.
