Current code does not allow fixed voltage range in multiple linear ranges.
If someone does set range->uV_step == 0 in one of the linear ranges, we hit
divided by zero bug. This patch fixes this issue.
For fixed voltage range, return any selector means the same voltage.
Thus just return 0.

Signed-off-by: Mark Brown <broonie@linaro.org>
Many regulators have several linear ranges of selector with different
step sizes, for example offering better resolution at lower voltages.
Provide regulator_{map,list}_voltage_linear_range() allowing these
regulators to use generic code. To do so a table of regulator_linear_range
structs needs to be pointed to from the descriptor.
This was inspired by similar code included in a driver submission from
Chao Xie and Yi Zhang at Marvell.

The bits in BRIDGE_CAUSE are documented as RW0C - read, write 0 to
clear. If we read the register, mask off the watchdog bit, and
write it back, we're actually clearing every interrupt which wasn't
pending at the time we read the register - and that is racy.
Fix this to only write ~WATCHDOG_BIT to the register, which means
we write as zero only the watchdog bit.

The watchdog infrastructure in Dove is no different from that in
Orion5x or Kirkwood, so let's enable it for Dove. The only things
missing are a few register settings in Dove's bridge-regs.h.
Rather than duplicating the same register bit masks for the RSTOUTn_MASK
and BRIDGE_CAUSE registers, move the definitions into the watchdog
driver itself.

preferred paths for different device regions.
Fix a bug in the verity target that prevented its use with some
specific sizes of devices.
Improve some locking mechanisms in the device-mapper core and bufio.

Pull SCSI target updates from Nicholas Bellinger:
"Lots of activity this round on performance improvements in target-core
while benchmarking the prototype scsi-mq initiator code with
vhost-scsi fabric ports, along with a number of iscsi/iser-target
improvements and hardening fixes for exception path cases post v3.10
merge.
The highlights include:
- Make persistent reservations APTPL buffer allocated on-demand, and
drop per t10_reservation buffer. (grover)
- Make virtual LUN=0 a NULLIO device, and skip allocation of NULLIO
device pages (grover)
- Add transport_cmd_check_stop write_pending bit to avoid extra
access of ->t_state_lock is WRITE I/O submission fast-path. (nab)
- Drop unnecessary CMD_T_DEV_ACTIVE check from
transport_lun_remove_cmd to avoid extra access of ->t_state_lock in
release fast-path. (nab)
- Avoid extra t_state_lock access in __target_execute_cmd fast-path
(nab)
- Drop unnecessary vhost-scsi wait_for_tasks=true usage +
->t_state_lock access in release fast-path. (nab)
- Convert vhost-scsi to use modern se_cmd->cmd_kref
TARGET_SCF_ACK_KREF usage (nab)
- Add tracepoints for SCSI commands being processed (roland)
- Refactoring of iscsi-target handling of ISCSI_OP_NOOP +
ISCSI_OP_TEXT to be transport independent (nab)
- Add iscsi-target SendTargets=$IQN support for in-band discovery
(nab)
- Add iser-target support for in-band discovery (nab + Or)
- Add iscsi-target demo-mode TPG authentication context support (nab)
- Fix isert_put_reject payload buffer post (nab)
- Fix iscsit_add_reject* usage for iser (nab)
- Fix iscsit_sequence_cmd reject handling for iser (nab)
- Fix ISCSI_OP_SCSI_TMFUNC handling for iser (nab)
- Fix session reset bug with RDMA_CM_EVENT_DISCONNECTED (nab)
The last five iscsi/iser-target items are CC'ed to stable, as they do
address issues present in v3.10 code. They are certainly larger than
I'd like for stable patch set, but are important to ensure proper
REJECT exception handling in iser-target for 3.10.y"
