Merge tag 'char-misc-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char / misc / IIO / and others driver updates from Greg KH:
"Here is the char/misc/iio and other smaller driver subsystem updates
for 7.1-rc1. Lots of stuff in here, all tiny, but relevant for the
different drivers they touch. Major points in here is:
- the usual large set of new IIO drivers and updates for that
subsystem (the large majority of this diffstat)
- lots of comedi driver updates and bugfixes
- coresight driver updates
- interconnect driver updates and additions
- mei driver updates
- binder (both rust and C versions) updates and fixes
- lots of other smaller driver subsystem updates and additions
All of these have been in linux-next for a while with no reported
issues"

SPMI PMIC5 Gen3 voltage ADC (ADC) provides interface to clients to read
|
||||
voltage. It is a 16-bit sigma-delta ADC. It also performs the same thermal
|
||||
monitoring function as the existing ADC_TM devices.
|
||||
|
||||
The interface is implemented on SDAM (Shared Direct Access Memory) peripherals
|
||||
on the master PMIC rather than a dedicated ADC peripheral. The number of PMIC
|
||||
SDAM peripherals allocated for ADC is not correlated with the PMIC used, it is
|
||||
programmed in FW (PBS) and is fixed per SOC, based on the SOC requirements.
|
||||
All boards using a particular (SOC + master PMIC) combination will have the
|
||||
same number of ADC SDAMs supported on that PMIC.
