[PATCH v2 0/7] ARM: SPEAr600 updates

[PATCH v2 0/7] ARM: SPEAr600 updates

[Thomas Petazzoni]

Arnd, Olof, Mike, Stephen,

Here are a set of patches touching the support of the SPEAr600
platform, for which the platform maintained Viresh Kumar has Acked the
patches, but would like the arm-soc and clk maintainers to pick up the
patches directly, see
http://lists.infradead.org/pipermail/linux-arm-kernel/2017-April/501653.html.

Arnd, Olof, could you pick patches 1 to 6 directly in your arm-soc tree ?

Mike, Stephen, could you pick patch 7 directly in your clk tree ?

Thanks a lot,

Thomas Petazzoni

Thomas Petazzoni (7):
  arm: spear6xx: add labels to various nodes in spear600.dtsi
  arm: spear6xx: use node labels in spear600-evb.dts
  arm: spear6xx: fix spaces in spear600-evb.dts
  arm: spear6xx: switch spear600-evb to the new flash partition DT
    binding
  arm: spear6xx: remove unneeded pinctrl properties in spear600-evb
  arm: spear6xx: add DT description of the ADC on SPEAr600
  clk: spear: fix ADC clock definition on SPEAr600

[PATCH v2 1/7] arm: spear6xx: add labels to various nodes in spear600.dtsi

[Thomas Petazzoni]

Having labels allows to more easily reference nodes in .dts files
including spear600.dtsi.

[PATCH v2 4/7] arm: spear6xx: switch spear600-evb to the new flash partition DT binding

[Thomas Petazzoni]

This commit moves spear600-evb.dts to use the new flash partition Device
Tree binding documented in
Documentation/devicetree/bindings/mtd/partition.txt.

As this Device Tree binding document says: "For backwards compatibility
partitions as direct subnodes of the mtd device are supported. This use
is discouraged."

[PATCH v2 5/7] arm: spear6xx: remove unneeded pinctrl properties in spear600-evb

[Thomas Petazzoni]

The spear6xx doesn't have a pinctrl driver, since the pinmux is globally
defined through a single register, generally configured by the
firmware/bootloader.

Therefore, the pinctrl related properties in spear600-evb.dts are not
necessary.

[Thomas Petazzoni]

There is no SPEAr600 device named "adc". Instead, the description of the
ADC was recently added to the Device Tree, and the device name is
"d820b000.adc", so we should associate the ADC gatable clock to this
device name.
