Hi Sekhar et al,

please take a look at the following patches. They add a simple genpd
driver and use it in DT mode on da850 boards.

I was trying to use genpd in legacy mode too, but couldn't find neither
any interfaces nor users that would do that. For now I added a check in
arch/arm/mach-davinci/pm_domain.c that disables the clock pm setup if
we're using genpd.

This series applies on top of and has been tested with David Lechner's
for-bartosz branch. It fixes the clock look-up issues we faced with
lcdc and emac.

Bartosz Golaszewski (7):
  dt-bindings: soc: new driver for DaVinci genpd
  soc: davinci: new genpd driver
  ARM: davinci: don't setup pm_clk if we're using genpd
  ARM: dts: da850: add power controller nodes
  ARM: dts: da850: add power-domains properties to device nodes
  ARM: davinci: select generic power domains for DaVinci in DT mode
  ARM: davinci_all_defconfig: select the DaVinci genpd driver in DT mode
