commit ad02e846878ca35e9d3fa584be8ee770e9e14fce
Author: Axel Lin <axel.lin@ingics.com>

    regulator: palmas: Return raw register values as the selectors in [get|set]_voltage_sel

    Don't adjust the selector in [get|set]_voltage_sel, fix it in list_voltage() instead.

    For smps*(except smps10), the vsel reg-value and voltage mapping as below:
----------
The list_voltage() takes the true value of selector which is
programmed in the register.  As per smsp voltage table
    reg-value       volt (uV) ( Assume RANGE is x1 )
    0               0
    1               500000
    2               500000
    3               500000
    4               500000
    5               500000
    6               500000 (0.49V + 1 * 0.01V) * RANGE
    7               510000 (0.49V + 2 * 0.01V) * RANGE
    8               520000 (0.49V + 3 * 0.01V) * RANGE
    9               530000 (0.49V + 4 * 0.01V) * RANGE
    ....
    121            1650000 (0.49V + 116 * 0.1) * RANGE

Hence making n_voltages for smps to 122.

regulator: palmas: configure enable time for LDOs

As per datasheet (Referred TPS65913), the on-time for LDO is
500micro second. If LDO6 is in vibrator mode then the on-time
is 2000us.

Set the enable_time on regulator descriptor accordingly.

Bluetooth: Fix security level for peripheral role

While playing the peripheral role, the host gets a LE Long Term Key
Request Event from the controller when a connection is established
with a bonded device. The host then informs the LTK which should be
used for the connection. Once the link is encrypted, the host gets
an Encryption Change Event.

Therefore we should set conn->pending_sec_level instead of conn->
sec_level in hci_le_ltk_request_evt. This way, conn->sec_level is
properly updated in hci_encrypt_change_evt.

Moreover, since we have a LTK associated to the device, we have at
least BT_SECURITY_MEDIUM security level.

Bluetooth: Fix ACL alive for long in case of non pariable devices

For certain devices (ex: HID mouse), support for authentication,
pairing and bonding is optional. For such devices, the ACL alive
for too long after the L2CAP disconnection.

To avoid the ACL alive for too long after L2CAP disconnection, reset the
ACL disconnect timeout back to HCI_DISCONN_TIMEOUT during L2CAP connect.

While merging the commit id:a9ea3ed9b71cc3271dd59e76f65748adcaa76422

regulator: palmas: Remove wrong comment for the equation calculating num_voltages

Current equation on the comment is wrong.
For linear mapping starting from 0, the equation is (maxV-minV)/stepV + 1.
Since the linear mapping for PALMAS is not all starting from 0, the equation
on the comment is not useful and misleading. Thus remove it.
