 "We have two changes to the core framework this time around.

  The first being a large change that introduces runtime PM support to
  the clk framework. Now we properly call runtime PM operations on the
  device providing a clk when the clk is in use. This helps on SoCs
  where the clks provided by a device need something to be powered on

  The other core change is a devm API addition for clk providers so we

PCI: Add devm_pci_alloc_host_bridge() interface 2017-06-28T20:13:53+00:00 Lorenzo Pieralisi lorenzo.pieralisi@arm.com 2017-06-28T20:13:53+00:00 5c3f18cce08364ef68163228c0b42725d64cd353 Struct pci_host_bridge can be allocated by PCI host bridge drivers which usually allocate and map memory through devm managed interfaces.
