Subject: [PATCHv2 0/6] Add a driver for the atmel ram controller

The atmel ram controller needs one or more clocks to work. For now the
CLK_IGNORE_UNUSED flag is used on those clocks. This patch set introduce a
driver that will take care of taking those clocks.

The final goal is also to move the ioremap done in mach-at91 to that driver with
a proper power management driver.

Changes in v2:
 - use ATMEL_SDRAMC instead of ATMEL_RAMC
 - use "atmel,sama5d3-ddramc" instead of "atmel,sama5d3-mpddramc"
 - not getting mpddrck is now an error
 - handle "atmel,sama5d3-ddramc" in mach-at91/setup.c

Alexandre Belloni (6):
  ARM: at91: Add new binding for sama5d3-ddramc
  memory: add a driver for atmel ram controllers
  ARM: at91: select ATMEL_SDRAMC when using OF
  ARM: at91/dt: sama5d3: define mpddr clock and ramc clocks
  ARM: at91/dt: at91sam9: use ddrck in ramc
  clk: at91: remove the useless CLK_IGNORE_UNUSED flag
