commit cf2b012c90e74e85d8aea7d67e48868069cfee0c upstream.
Change 21537dc driver PMBus polling of MFR_COMMON from bits 5/4 to
bits 6/5. This fixs a LTC297X family bug where polling always returns
not busy even when the part is busy. This fixes a LTC388X and
LTM467X bug where polling used PEND and NOT_IN_TRANS, and BUSY was
not polled, which can lead to NACKing of commands. LTC388X and
LTM467X modules now poll BUSY and PEND, increasing reliability by
eliminating NACKing of commands.Signed-off-by: Mike Jones

commit e51a7dda299815e92f43960d620cdfc8dfc144f2 upstream.
No alarm is reported by /sys/.../inX_alarm
In detail:
The SMI Voltage status register is the only register giving a status
for voltages, but it does not work like the non-SMI status registers
used for temperatures and fans.
A bit is set for each input crossing a threshold, in both direction,
but the "inside" or "outside" limits info is not available.
Also this register is cleared on read.
Note : this is not explicitly spelled out in the datasheet, but from
experiment.
As a result if an input is crossing a threshold (min or max in any
direction), the alarm is reported only once even if the input is
still outside limits. Also if the alarm for another input is read
before the one of this input, no alarm is reported at all.Signed-off-by: Gilles Buloz

commit 3bf8bdcf3bada771eb12b57f2a30caee69e8ab8d upstream.
The hwmon core uses device managed functions, tied to the hwmon parent
device, for various internal memory allocations. This is problematic
since hwmon device lifetime does not necessarily match its parent's
device lifetime. If there is a mismatch, memory leaks will accumulate
until the parent device is released.Fix the problem by managing all memory allocations internally. The only
exception is memory allocation for thermal device registration, which
can be tied to the hwmon device, along with thermal device registration
itself.Fixes: d560168b5d0f ("hwmon: (core) New hwmon registration API")

commit cf3ca1877574a306c0207cbf7fdf25419d9229df upstream.
reg2volt returns the voltage that matches a given register value.
Converting this back the other way with volt2reg didn't return the same
register value because it used truncation instead of rounding.This meant that values read from sysfs could not be written back to sysfs
to set back the same register value.With this change, volt2reg will return the same value for every voltage
previously returned by reg2volt (for the set of possible input values)Signed-off-by: Luuk Paulussen

commit 92b39ad440968bab38eb6577d63c12994601ed94 upstream.
The LED blink_set function incorrectly did not tell the PSU LED to blink
if brightness was LED_OFF. Fix this, and also correct the LED_OFF
command data, which should give control of the LED back to the PSU
firmware. Also prevent I2C failures from getting the driver LED state
out of sync and add some dev_dbg statements.Signed-off-by: Eddie James

After introducing "samples" to the calculation of wait time, the
driver might timeout at the regmap_field_read_poll_timeout call,
because the wait time could be longer than the 100000 usec limit
due to a large "samples" number.So this patch sets the timeout limit to 2 times of the wait time
in order to fix this issue.Fixes: 5c090abf945b ("hwmon: (ina3221) Add averaging mode support")

Pull MIPS updates from Paul Burton:
"Main MIPS changes:- boot_mem_map is removed, providing a nice cleanup made possible by
the recent removal of bootmem.- Some fixes to atomics, in general providing compiler barriers for
smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs
or MIPS32 systems using cmpxchg64().- Conversion to the new generic VDSO infrastructure courtesy of
Vincenzo Frascino.- Removal of undefined behavior in set_io_port_base(), fixing the
behavior of some MIPS kernel configurations when built with recent
clang versions.- Initial MIPS32 huge page support, functional on at least Ingenic
SoCs.- pte_special() is now supported for some configurations, allowing
among other things generic fast GUP to be used.- Miscellaneous fixes & cleanups.
And platform specific changes:
- Major improvements to Ingenic SoC support from Paul Cercueil,
mostly enabled by the inclusion of the new TCU (timer-counter unit)
drivers he's spent a very patient year or so working on. Plus some
fixes for X1000 SoCs from Zhou Yanjie.- Netgear R6200 v1 systems are now supported by the bcm47xx platform.

Pull driver core updates from Greg Kroah-Hartman:
"Here is the big driver core update for 5.4-rc1.There was a bit of a churn in here, with a number of core and OF
platform patches being added to the tree, and then after much
discussion and review and a day-long in-person meeting, they were
decided to be reverted and a new set of patches is currently being
reviewed on the mailing list.Other than that churn, there are two "persistent" branches in here
that other trees will be pulling in as well during the merge window.
One branch to add support for drivers to have the driver core
automatically add sysfs attribute files when a driver is bound to a
device so that the driver doesn't have to manually do it (and then
clean it up, as it always gets it wrong).There's another branch in here for generic lookup helpers for the
driver core that lots of busses are starting to use. That's the
majority of the non-driver-core changes in this patch series.There's also some on-going debugfs file creation cleanup that has been
slowly happening over the past few releases, with the goal to
hopefully get that done sometime next year.All of these have been in linux-next for a while now with no reported
issues"[ Note that the above-mentioned generic lookup helpers branch was
already brought in by the LED merge (commit 4feaab05dc1e) that had
shared it.Also note that that common branch introduced an i2c bug due to a bad
conversion, which got fixed here. - Linus ]* tag 'driver-core-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (49 commits)

Conversion time: 75, 150, 300, 600 ms
Sensor resolution: 9, 10, 11, 12 bit
TMP100, TMP101:
Conversion time: 75, 150, 300, 600 ms
Sensor resolution: 9, 10, 11, 12 bit
TMP75, TMP105, TMP175, TMP275:
Conversion time: 38, 75, 150, 300 ms
Sensor resolution: 9, 10, 11, 12 bitWhile doing this, it became obvious that the masks and values to set
the converion (sample) time is similar for all those chips, and that
other chips with configurable sample times will need separate code anyway.
For that reason, replace the sample_set_masks and sample_clr_mask
configuration parameters with a single array and with a constant.Signed-off-by: Guenter Roeck

According to kernel hwmon sysfs-interface documentation, temperature
critical max value, typically greater than corresponding temp_max values.
Thus, reads the LTD_HV_HL (LTD HIGH VALUE HIGH LIMITATION) and LTD_LV_HL
(LTD LOW VALUE HIGH LIMITATION) for case hwmon_temp_crit and
hwmon_temp_crit_hyst. Reads the LTD_HV_LL (HIGH VALUE LOW LIMITATION)
and LTD_LV_LL (LOW VALUE LOW LIMITATION) for case hwmon_temp_max
and hwmon_temp_max_hyst.Signed-off-by: amy.shih
