2023-02-22backlight: pwm_bl: Don't rely on a disabled PWM emiting inactive stateUwe Kleine-König
Most but not all PWMs drive the PWM pin to its inactive state when disabled. However if there is no enable_gpio and no regulator the PWM must drive the inactive state to actually disable the backlight. So keep the PWM on in this case. Note that to determine if there is a regulator some effort is required because it might happen that there isn't actually one but the regulator core gave us a dummy. (A nice side effect is that this makes the regulator actually optional even on fully constrained systems.) This fixes backlight disabling e.g. on i.MX6 when an inverted PWM is used. Hint for the future: If this change results in a regression, the bug is in the lowlevel PWM driver.

2023-02-22backlight: pwm_bl: Configure pwm only once per backlight toggleUwe Kleine-König
When the function pwm_backlight_update_status() was called with brightness > 0, pwm_get_state() was called twice (once directly and once in compute_duty_cycle). Also pwm_apply_state() was called twice (once in pwm_backlight_power_on() and once directly). Optimize this to do both calls only once. Note that with this affects the order of regulator and PWM setup. It's not expected to have a relevant effect on hardware. The rationale for this is that the regulator (and the GPIO) are reasonable to switch in pwm_backlight_power_on()/pwm_backlight_power_off() but the PWM has nothing to do with power. (The post_pwm_on_delay and pwm_off_delay are still there though.)

2023-02-22wifi: ath11k: allow system suspend to survive ath11kLen Brown
When ath11k runs into internal errors upon suspend, it returns an error code to pci_pm_suspend, which aborts the entire system suspend. The driver should not abort system suspend, but should keep its internal errors to itself, and allow the system to suspend. Otherwise, a user can suspend a laptop by closing the lid and sealing it into a case, assuming that is will suspend, rather than heating up and draining the battery when in transit. In practice, the ath11k device seems to have plenty of transient errors, and subsequent suspend cycles after this failure often succeed. https://bugzilla.kernel.org/show_bug.cgi?id=216968 Fixes: d1b0c33850d29 ("ath11k: implement suspend for QCA6390 PCI devices") Signed-off-by: Len Brown <len.brown@intel.com> Cc: stable@vger.kernel.org Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230201183201.14431-1-len.brown@intel.com

2023-02-22mfd: axp20x: Switch to the sys-off handler APISamuel Holland
This removes a layer of indirection through pm_power_off() and allows the PMIC handler to be used as a fallback when firmware power off fails. This happens on boards like the Clockwork DevTerm R-01 where OpenSBI does not know how to use the PMIC to power off the board. Move the check for AXP288 to avoid registering a dummy handler.

2023-02-22mfd: twl4030-power: Drop empty platform remove functionUwe Kleine-König
A remove callback just returning 0 is equivalent to no remove callback at all. So drop the useless function.

2023-02-22mfd: twl: Fix TWL6032 phy vbus detectionAndreas Kemnade
TWL6032 has a few charging registers prepended before the charging registers the TWL6030 has. To be able to use common register defines declare the additional registers as additional module. At the moment this affects the access to CHARGERUSB_CTRL1 in phy-twl6030-usb. Without this patch, it is accessing the wrong register on TWL6032. The consequence is that presence of Vbus is not reported.

`req` is allocated in pcf50633_adc_async_read(), but adc_enqueue_request() could fail to insert the `req` into queue. We need to check the return value and free it in the case of failure.
