Subject: [PATCH 00/10] ARM: da850-lcdk: add SATA support

This series contains all the changes necessary to make SATA work on
the da850-lcdk board.

The first patch adds a clock lookup entry required for the ahci core
to retrieve a functional clock.

The second enables relevant config options for all davinci boards.

The third adds device tree bindings for the ahci_da850 driver.

The fourth adds a workaround for a SATA controller instability we
detected after increasing the PLL0 frequency for proper LCD
controller support.

Patches 5 through 7 extend the ahci_da850 driver - add DT support,
un-hardcode the clock multiplier value and add a workaround for
a quirk present on the da850 SATA controller.

Patches 8-10 add the device tree changes required to probe the driver.

I'm posting the series as a whole to give all reviewers the full
picture and visibility of the changes required, if needed I can resend
the patches separately.

Bartosz Golaszewski (10):
  ARM: davinci: add a clock lookup entry for the SATA clock
  ARM: davinci_all_defconfig: enable SATA modules
  devicetree: bindings: add bindings for ahci-da850
  sata: hardreset: retry if phys link is down
  sata: ahci_da850: add device tree match table
  sata: ahci_da850: implement a softreset quirk
  sata: ahci_da850: add support for the da850,clk_multiplier DT property
  ARM: dts: da850: add pinmux settings for the SATA controller
  ARM: dts: da850: add the SATA node
  ARM: dts: da850-lcdk: enable the SATA node
