This modifies the ad7944 driver to use spi_optimize_message() to reduce CPU usage and increase the max sample rate by avoiding repeating validation of the spi message on each transfer.

On some designs the chip is not properly reset when powered up at boot or after a suspend/resume cycle. Use the sw-reset feature to ensure that the chip is in a clean state after probe() / resume() and in the case of resume() restore the settings (scale, trigger-enabled).

2024-03-28iio: accel: mxc4005: Interrupt handling fixesHans de Goede1-7/+17
There are 2 issues with interrupt handling in the mxc4005 driver: 1. mxc4005_set_trigger_state() writes MXC4005_REG_INT_MASK1_BIT_DRDYE (0x01) to INT_MASK1 to enable the interrupt, but to disable the interrupt it writes ~MXC4005_REG_INT_MASK1_BIT_DRDYE which is 0xfe, so it enables all other interrupt sources in the INT_SRC1 register. On the MXC4005 this is not an issue because only bit 0 of the register is used. On the MXC6655 OTOH this is a problem since bit7 is used as TC (Temperature Compensation) disable bit and writing 1 to this disables Temperature Compensation which should only be done when running self-tests on the chip. Write 0 instead of ~MXC4005_REG_INT_MASK1_BIT_DRDYE to disable the interrupts to fix this. 2. The datasheets for the MXC4005 / MXC6655 do not state what the reset value for the INT_MASK0 and INT_MASK1 registers is and since these are write only we also cannot learn this from the hw. Presumably the reset value for both is all 0, which means all interrupts disabled. Explicitly set both registers to 0 from mxc4005_chip_init() to ensure both masks are actually set to 0.

2024-03-25iio: adc: ad7944: Add support for "3-wire mode"David Lechner1-18/+139
This adds support for AD7944 ADCs wired in "3-wire mode". (NOTE: 3-wire is the datasheet name for this wiring configuration and has nothing to do with SPI_3WIRE.) In the 3-wire mode, the SPI controller CS line can be wired to the CNV line on the ADC and used to trigger conversions rather that using a separate GPIO line. The turbo/chain mode compatibility check at the end of the probe function is technically can't be triggered right now but adding it now anyway so that we don't forget to add it later when support for daisy-chaining is added.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc Pull char/misc and other driver subsystem updates from Greg KH: "Here is the big set of char/misc and a number of other driver subsystem updates for 6.9-rc1. Included in here are: - IIO driver updates, loads of new ones and evolution of existing ones - coresight driver updates - const cleanups for many driver subsystems - speakup driver additions - platform remove callback void cleanups - mei driver updates - mhi driver updates - cdx driver updates for MSI interrupt handling - nvmem driver updates - other smaller driver updates and cleanups, full details in the shortlog All of these have been in linux-next for a long time with no reported issue, other than a build warning for the speakup driver" The build warning hits clang and is a gcc (and C23) extension, and is fixed up in the merge.
