[PATCH 0/4] add minimal bcm2835-sdram driver

[kernel@martin.sperl.org]

From: Martin Sperl <kernel@martin.sperl.org>

As the sdram clock is a critical clock to the system
the minimal bcm2835-sdram driver claims (and enables)
this clock and also exposes the corresponding sdram
registers via debugfs.

Martin Sperl (4):
  dt: bindings: add bcm2835-memory-controller documentation
