Pull char/misc and other driver updates from Greg KH: "Here is the large set of char/misc and other small driver subsystem changes for 6.1-rc1. Loads of different things in here: - IIO driver updates, additions, and changes. Probably the largest part of the diffstat - habanalabs driver update with support for new hardware and features, the second largest part of the diff. - fpga subsystem driver updates and additions - mhi subsystem updates - Coresight driver updates - gnss subsystem updates - extcon driver updates - icc subsystem updates - fsi subsystem updates - nvmem subsystem and driver updates - misc driver updates - speakup driver additions for new features - lots of tiny driver updates and cleanups All of these have been in the linux-next tree for a while with no reported issues" * tag 'char-misc-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (411 commits) w1: Split memcpy() of struct cn_msg flexible array spmi: pmic-arb: increase SPMI transaction timeout delay spmi: pmic-arb: block access for invalid PMIC arbiter v5 SPMI writes spmi: pmic-arb: correct duplicate APID to PPID mapping logic spmi: pmic-arb: add support to dispatch interrupt based on IRQ status spmi: pmic-arb: check apid against limits before calling irq handler spmi: pmic-arb: do not ack and clear peripheral interrupts in cleanup_irq spmi: pmic-arb: handle spurious interrupt spmi: pmic-arb: add a print in cleanup_irq drivers: spmi: Directly use ida_alloc()/free() MAINTAINERS: add TI ECAP driver info counter: ti-ecap-capture: capture driver support for ECAP Documentation: ABI: sysfs-bus-counter: add frequency & num_overflows items dt-bindings: counter: add ti,am62-ecap-capture.yaml counter: Introduce the COUNTER_COMP_ARRAY component type counter: Consolidate Counter extension sysfs attribute creation counter: Introduce the Count capture component counter: 104-quad-8: Add Signal polarity component counter: Introduce the Signal polarity component counter: interrupt-cnt: Implement watch_validate callback ...

iio: dac: ad5593r: Fix i2c read protocol requirements

2022-09-21T17:42:53Z

For reliable operation across the full range of supported interface rates, the AD5593R needs a STOP condition between address write, and data read (like show in the datasheet Figure 40) so in turn i2c_smbus_read_word_swapped cannot be used. While at it, a simple helper was added to make the code simpler.

i2c: Make remove callback return void

2022-08-16T10:46:26Z

The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

Using these newer macros allows the compiler to remove the unused structure and functions when !CONFIG_PM_SLEEP + removes the need to mark pm functions __maybe_unused.

iio: dac: cio-dac: Cleanup indexing for DAC writes

2022-07-16T17:48:20Z

Simplify DAC write code by defining base member as u16 __iomem *; DAC registers are 16-bit so this allows us to index each DAC channel directly in a loop rather than calculating the offsets by multipling by 2 each time.
