Merge tag 'davinci-for-v4.19/soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into next/soc

DaVinci SoC updates for v4.19
-----------------------------

* mach-davinci updates needed to finally move over to common clock framework
* update to use the aemif driver from drivers/memory rather than the
  private implementation available in mach-davinci

For the later item, I have included a branch from David Lechner which
should also get merged through the clk tree. The clk dependencies are
needed for aemif conversion.

* tag 'davinci-for-v4.19/soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci: (34 commits)

  clk: davinci: psc-dm644x: use two lookup entries for the aemif clock
  clk: davinci: psc-dm365: use two lookup entries for the aemif clock
  clk: davinci: psc-da850: remove the 'davinci_nand.0" lookup
  ARM: davinci: da8xx-dt: switch to device tree clocks
  ARM: davinci: add device tree support to timer
  ARM: davinci: remove legacy clocks
