2022-06-20ARM: dts: imx6q-apalis: Command pmic to standby for poweroffMax Krummenacher1-0/+5
The Apalis iMX6 HW doesn't allow to use the PWR_ON_REQ signal for poweroff. Use the fsl,pmic-stby-poweroff property to command the PMIC into a low power mode in poweroff. Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

2022-06-19random: quiet urandom warning ratelimit suppression messageJason A. Donenfeld2-5/+9
random.c ratelimits how much it warns about uninitialized urandom reads using __ratelimit(). When the RNG is finally initialized, it prints the number of missed messages due to ratelimiting. It has been this way since that functionality was introduced back in 2018. Recently, cc1e127bfa95 ("random: remove ratelimiting for in-kernel unseeded randomness") put a bit more stress on the urandom ratelimiting, which teased out a bug in the implementation. Specifically, when under pressure, __ratelimit() will print its own message and reset the count back to 0, making the final message at the end less useful. Secondly, it does so as a pr_warn(), which apparently is undesirable for people's CI. Fortunately, __ratelimit() has the RATELIMIT_MSG_ON_RELEASE flag exactly for this purpose, so we set the flag.

2022-06-19random: schedule mix_interrupt_randomness() less oftenJason A. Donenfeld1-1/+1
It used to be that mix_interrupt_randomness() would credit 1 bit each time it ran, and so add_interrupt_randomness() would schedule mix() to run every 64 interrupts, a fairly arbitrary number, but nonetheless considered to be a decent enough conservative estimate. Since e3e33fc2ea7f ("random: do not use input pool from hard IRQs"), mix() is now able to credit multiple bits, depending on the number of calls to add(). This was done for reasons separate from this commit, but it has the nice side effect of enabling this patch to schedule mix() less often. Currently the rules are: a) Credit 1 bit for every 64 calls to add(). b) Schedule mix() once a second that add() is called. c) Schedule mix() once every 64 calls to add(). Rules (a) and (c) no longer need to be coupled. It's still important to have _some_ value in (c), so that we don't "over-saturate" the fast pool, but the once per second we get from rule (b) is a plenty enough baseline. So, by increasing the 64 in rule (c) to something larger, we avoid calling queue_work_on() as frequently during irq storms. This commit changes that 64 in rule (c) to be 1024, which means we schedule mix() 16 times less often. And it does *not* need to change the 64 in rule (a).

2022-06-19iio:accel:bma180: rearrange iio trigger get and registerDmitry Rokosov1-1/+2
IIO trigger interface function iio_trigger_get() should be called after iio_trigger_register() (or its devm analogue) strictly, because of iio_trigger_get() acquires module refcnt based on the trigger->owner pointer, which is initialized inside iio_trigger_register() to THIS_MODULE. If this call order is wrong, the next iio_trigger_put() (from sysfs callback or "delete module" path) will dereference "default" module refcnt, which is incorrect behaviour.

2022-06-19iio: afe: rescale: Fix boolean logic bugLinus Walleij1-1/+1
When introducing support for processed channels I needed to invert the expression: if (!iio_channel_has_info(schan, IIO_CHAN_INFO_RAW) || !iio_channel_has_info(schan, IIO_CHAN_INFO_SCALE)) dev_err(dev, "source channel does not support raw/scale\n"); To the inverse, meaning detect when we can usse raw+scale rather than when we can not. This was the result: if (iio_channel_has_info(schan, IIO_CHAN_INFO_RAW) || iio_channel_has_info(schan, IIO_CHAN_INFO_SCALE)) dev_info(dev, "using raw+scale source channel\n"); Ooops. Spot the error. Yep old George Boole came up and bit me. That should be an &&. The current code "mostly works" because we have not run into systems supporting only raw but not scale or only scale but not raw, and I doubt there are few using the rescaler on anything such, but let's fix the logic.

2022-06-19iio: adc: stm32: Fix IRQs on STM32F4 by removing custom spurious IRQs messageYannick Brosseau1-10/+0
The check for spurious IRQs introduced in 695e2f5c289bb assumed that the bits in the control and status registers are aligned. This is true for the H7 and MP1 version, but not the F4. The interrupt was then never handled on the F4. Instead of increasing the complexity of the comparison and check each bit specifically, we remove this check completely and rely on the generic handler for spurious IRQs.

2022-06-19iio: adc: stm32: Fix ADCs iteration in irq handlerYannick Brosseau1-1/+6
The irq handler was only checking the mask for the first ADCs in the case of the F4 and H7 generation, since it was iterating up to the num_irq value. This patch add the maximum number of ADC in the common register, which map to the number of entries of eoc_msk and ovr_msk in stm32_adc_common_regs. This allow the handler to check all ADCs in that module. Tested on a STM32F429NIH6.

The call chain generic_handle_irq(irq_find_mapping(domain, x)); could be replaced with generic_handle_domain_irq(domain, x); which looks up the struct irq_desc for the interrupt and handles it with handle_irq_desc(). This is a slight optimisation given that the driver invokes only one function and the struct irq_desc is used directly instead being looked up via irq_to_desc(). Use generic_handle_domain_irq().
