e9bc0691a8 EXTRES: Add OF node as argument to all <foo>_get_by_ofw_<bar>() functions.
In some cases, the driver must handle given properties located in
specific OF subnode. Instead of creating duplicate set of function, add
'node' as argument to existing functions, defaulting it to device OF node.

d023278015 Add clk_get_by_ofw_node_index, which is like clk_get_by_ofw_index but
operates on a specific OF node instead of the pass in device's OF node.

59d1116142 Rename gpiobus_map_pin() to gpiobus_acquire_pin(), to better reflect the
fact that the caller is requesting exclusive use of the pin, and also to
better match the inverse operation which is named gpiobus_release_pin().

97f3d1acfd Fix support for fixed factor clocks.
- Use a different device description for fixed and fixed factor clocks.
 - Fix a bug where the "clock-div" property was stored in the "mult" field
   of the clock definition.
 - Get the fixed factor parent clock by index instead of by name, as a
   clock-names property is not required to be present here.

998178b74f clk_parse_ofw_out_names is supposed to return a list of indices when the
clock-indices property is present, so change the "uint32_t *indices" parameter
to "uint32_t **indices" to allow this.

0b12b4f6b6 Return BUS_PROBE_GENERIC instead of 0 from ofw_clkbus_probe, giving
platform specific drivers a chance to override the generic driver.

41527ba958 Add phy framework, a next part of new 'extended resources' family of
support frameworks (i.e. clk/regulators/tsensors/fuses...).

It provides simple unified consumers interface for manipulations with
phy (USB/SATA/PCIe) resources.

c3bb1016b8 Add regulator framework, a next part of new 'extended resources' family of
support frameworks(i.e. clk/reset/phy/tsensors/fuses...).

The framework is still far from perfect and probably doesn't have stable
interface yet, but we want to start testing it on more real boards and
different architectures.

d975ccbb1b Add clock framework, a first part of new 'extended resources' family of
support frameworks(i.e. reset/regulators/phy/tsensors/fuses...).

The clock framework significantly simplifies handling of complex clock
structures found in modern SoCs. It provides the unified consumers
interface, holds and manages actual clock topology, frequency and gating.

It's tested on three different ARM boards (Nvidia Tegra TK1, Inforce 6410 and
Odroid XU2) and on one MIPS board (Creator Ci20) by kan@.

The framework is still far from perfect and probably doesn't have stable
interface yet, but we want to start testing it on more real boards and
different architectures.
