Subject: [PATCH 0/6] ARM: davinci: common clock prep work

This series contains some changes needed for the conversion of arch/arm/mach-
davinci to the common clock framework.

Most of the boards in mach-davinci do not have device tree support. However,
CFGCHIP, which is a syscon regmap, is needed during clock init in early boot.
Using a platform device for the syscon at this point is not an option. So,
this series introduces a new way to register a syscon regmap on non-DT systems.

The DA8XX USB PHY driver is a consumer of the CFGCHIP syscon regmap, so some
changes are needed in that driver as well since we are removing the syscon
platform devices. The patch "phy: da8xx-usb: rename clock con_ids" doesn't
have anything to do with syscon, but I included in this series because we are
touching PHY code here anyway and it is also a dependency for the upcoming
common clock framework conversion changes.

Maintainers, please coordinate with Sekhar before committing. We will probably
want everything to go through the linux-davinci tree if possible.

David Lechner (6):
  mfd: syscon: Add syscon_register() function
  phy: da8xx-usb: Always check for syscon compatible
  phy: da8xx-usb: rename clock con_ids
  ARM: davinci: move davinci_clk_init() to init_time
  ARM: da8xx: Move CFGCHIP registration to init_time
  phy: da8xx-usb: drop use of syscon_regmap_lookup_by_pdevname()
