[PATCH 0/4] ARM: MMC: USB: Fix clocking

[Lee Jones]

Before we had critical-clock support, it was not possible to boot a kernel
without using the 'clk_ignore_unused' kernel command-line parameter.  This
was due to the existance of inter-connect clocks which weren't associated
with any physical device and thus could not be handled (think get, enable,
disable) correctly.  As a consequence the platform would catastrophically
fail when the Common Clock Framework tried to disable unused clocks.

Now we do have critical-clock support, it has identified some additional
clocks which are required for the successful functioning of some key IP.

With the introduction of critical-clock support in v4.8, our developers'
default configuration is to run with 'clk_ignore_unused' removed.  This
patch-set ensures they can achieve successful boot when a) booting from
an SD Card and when b) booting using USB->Eth adaptors for NFS booting.

Please consider this set for your respective -fixes branches for
inclusion into the v4.8-rcs.
