2021-11-05mfd: qcom-spmi-pmic: Sort compatibles in the driverBjorn Andersson
Sort the compatibles in the driver, to make it easier to validate that the DT binding and driver are in sync.

2021-11-05mfd: janz-cmoio: Replace snprintf in show functions with sysfs_emitQing Wang
show() must not use snprintf() when formatting the value to be returned to user space. Fix the following coccicheck warning: drivers/mfd/janz-cmodio.c:157: WARNING: use scnprintf or sprintf. Use sysfs_emit instead of scnprintf or sprintf makes more sense.

2021-11-05mfd: altera-sysmgr: Fix a mistake caused by resource_size conversionKai Song
The resource_size defines that: res->end - res->start + 1; The origin original code is: sysmgr_config.max_register = res->end - res->start - 3; So, the correct fix is that: sysmgr_config.max_register = resource_size(res) - 4; Fixes: d12edf9661a4 ("mfd: altera-sysmgr: Use resource_size function on resource object") Signed-off-by: Kai Song <songkai01@inspur.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20211006141926.6120-1-songkai01@inspur.com
2021-11-05mfd: arizona: Split of_match table into I2C and SPI versionsCharles Keepax
The Arizona driver has both some devices which only have an I2C interface and some which only have a SPI interface. Currently both of these share an of_match table, but this means inapproriate compatibles are available for each interface. Tidy this up by creating a table for each interface listing only the appropriate compatibles.

2021-11-05mfd: qcom-pm8xxx: switch away from using chained IRQ handlersDmitry Baryshkov
PM8xxx PMIC family uses GPIO as parent IRQ. Using it together with the irq_set_chained_handler_and_data() results in warnings from the GPIOLIB (see 461c1a7d4733 ("gpiolib: override irq_enable/disable")) as in this path the IRQ resources are not allocated (and thus the corresponding GPIO is not marked as used for the IRQ. Use request_irq so that the IRQ resources are proprely setup.

2021-11-05mfd: max14577: Do not enforce (incorrect) interrupt trigger typeKrzysztof Kozlowski
Interrupt line can be configured on different hardware in different way, even inverted. Therefore driver should not enforce specific trigger type - edge falling - but instead rely on Devicetree to configure it. The Maxim 14577/77836 datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct. The interrupt line is shared between PMIC and charger driver, so using level sensitive interrupt is here especially important to avoid races. With an edge configuration in case if first PMIC signals interrupt followed shortly after by the RTC, the interrupt might not be yet cleared/acked thus the second one would not be noticed.

2021-11-05PCI: Add ACS quirk for Pericom PI7C9X2G switchesNathan Rossi
The Pericom PI7C9X2G404/PI7C9X2G304/PI7C9X2G303 PCIe switches have an erratum for ACS P2P Request Redirect behaviour when used in the cut-through forwarding mode. The recommended work around for this issue is to use the switch in store and forward mode. The erratum results in packets being queued and not being delivered upstream, which can be observed as very poor downstream device performance and/or dropped device-generated data/interrupts. Add a fixup so that when enabling or resuming the downstream port we check if it has enabled ACS P2P Request Redirect, and if so, change the device (via the upstream port) to use the store and forward operating mode.

2021-11-05pwm: pwm-samsung: Trigger manual update when disabling PWMMårten Lindahl
When duty-cycle is at full level (100%), the TCNTn and TCMPn registers needs to be flushed in order to disable the signal. The PWM manual does not say anything about this, but states that only clearing the TCON auto-reload bit should be needed, and this seems to be true when the PWM duty-cycle is not at full level. This can be observed on an Axis ARTPEC-8, by running: echo <period> > pwm/period echo <period> > pwm/duty_cycle echo 1 > pwm/enable echo 0 > pwm/enable Since the TCNTn and TCMPn registers are activated when enabling the PWM (setting TCON auto-reload bit), and are not touched when disabling the PWM, the double buffered auto-reload function seems to be still active. Lowering duty-cycle, and restoring it again in between the enabling and disabling, makes the disable work since it triggers a reload of the TCNTn and TCMPn registers. Fix this by securing a reload of the TCNTn and TCMPn registers when disabling the PWM and having a full duty-cycle.
