[PATCH 0/6] Enable Nomadik NHK15 graphics

From: Linus Walleij <hidden>
Date: 2016-09-09 21:25:29

As all other pieces have been merged into the PWM and fbdev
subsystems, we can turn on graphics on the Nomadik NHK15
board.

Tested and works like a charm with boot penguin, console if
desired and fbsplash. Even blanks the screen properly to save
energy.

The missing DT bindings should probably have been merged in
the fbdev tree, but it doesn't matter where they are merged
so I plan to send this whole series as a pull request to
ARM SoC. The only non-DT change is the Kconfig change to
select MFD_SYSCON.

Linus Walleij (6):
  ARM: dts: add STMPE PWM to the NHK15 device tree
  dt-bindings: add vendor TPO
  dt-bindings: Add TPO TPG110 binding
  ARM: nomadik: select MFD_SYSCON
  ARM: dts: add PMU to the NHK15 device tree
  ARM: dts: add the CLCD LCD display to the NHK15

[PATCH 2/6] dt-bindings: add vendor TPO

From: Linus Walleij <hidden>
Date: 2016-09-09 21:25:31

TPO was a merger on June 5 2006 of Toppoly Optoelectronics and
Philips Mobile Display Systems. They manufactured small and medium
mobile displays.

[PATCH 4/6] ARM: nomadik: select MFD_SYSCON

From: Linus Walleij <hidden>
Date: 2016-09-09 21:25:33

Since the Power Management Unit is using syscon to access a
set of necessary hardware muxing, let's select MFD_SYSCON for
the Nomadik subarchitecture.

[PATCH 5/6] ARM: dts: add PMU to the NHK15 device tree

From: Linus Walleij <hidden>
Date: 2016-09-09 21:25:34

The so-called Nomadik Power Mangament Unit is actually a set
of some power management registers and some miscellaneous
system control stuff like muxing of entire hardware units.
Add this as a system controller.
