Supports larger register maps, not using unsigned ints for the full 32
bit as we rely on checking for negative registers.

The RC5T583 PMIC from RICOH consists of 4 DCDC and 10
LDOs. This driver supports the control of different
regulator output through regulator interface.
This driver depends on MFD driver of RC5T583 and uses
mfd rc5t583 apis to communicate to device for accessing
different device's registers.

Drivers should be able to declare their descriptors const and the framework
shouldn't ever be modifying the desciptor. Make the parameter and the
pointer in regulator_dev const to enforce this.

Unusual to see a regulator driver not using subsys_initcall() but the
deferred probe support should make this viable.

On a system running glibc trunk perf doesn't build:

Currently, most drivers do not support transmit SO_TIMESTAMPING. For those
that do support it, there is one appropriate response to the get_ts_info
query. This patch adds a common function providing this response.

This commit adds a new ethtool ioctl that exposes the SO_TIMESTAMPING
capabilities of a network interface. In addition, user space programs
can use this ioctl to discover the PTP Hardware Clock (PHC) device
associated with the interface.
Since software receive time stamps are handled by the stack, the generic
ethtool code can answer the query correctly in case the MAC or PHY
drivers lack special time stamping features.

In 72331bc [ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be
consistent with ipv4] the code of 'inet6_rtm_getroute()' was re-ordered
such that the reference to 'rt->dst' is incremented prior skb
allocation.
Hence, if 'alloc_skb()' fails, must drop a reference from 'rt->dst'.
Add the missing 'dst_release()' call.

This patch adds a source file implementing a PHC. Only the basic
clock operations have been implemented, although the hardware
would offer some ancillary functions. The code is fairly self
contained and is not yet used in the main igb driver.
Every timestamp and clock read operation must consult the overflow
counter to form a correct time value. Access to the counter is
protected by a spin lock, and the counter is implemented using the
standard cyclecounter/timecounter code.
