[PATCHv2 0/4] ACPI / LPSS: Solution for two issues seen on Asus T100

[Heikki Krogerus]

Changes since v1:
- now using do_div() in clk_fd_recalc_rate() as suggested by Andy
- NULL checks for clk_name allocation in acpi_lpss.c

This combines two patch sets for LPSS that I had already send for
review separately. They conflicted with each other.

The first two patches will fix a problem were the context of the
private LPSS registers is lost when entering D3. The last two will add
support for the M/N dividers on LPSS by adding a new basic clock type
for fractional dividers. The UART driver needs support for it in order
to get clock rates that suit the requested baud rates.

  ACPI / PM: Export rest of the subsys functions
  ACPI / LPSS: custom power domain for LPSS
  clk: new basic clk type for fractional divider
  ACPI / LPSS: support for fractional divider clock
