Input: pm8941-pwrkey - simulate missed key press events

2022-04-25T01:25:15+00:00

The status of the keys connected to the KPDPWR_N and RESIN_N pins is identified by reading corresponding bits in the interrupt real time status register. If the status has changed by the time that the interrupt is handled then a press event will be missed. Maintain a last known status variable to find unbalanced release events and simulate press events for each accordingly.

Input: pm8941-pwrkey - add software key press debouncing support

2022-04-25T01:25:13+00:00

On certain PMICs, an unexpected assertion of KPDPWR_DEB (the positive logic hardware debounced power key signal) may be seen during the falling edge of KPDPWR_N (i.e. a power key press) when it occurs close to the rising edge of SLEEP_CLK. This then triggers a spurious KPDPWR interrupt. Handle this issue by adding software debouncing support to ignore key events that occur within the hardware debounce delay after the most recent key release event.

Input: pm8941-pwrkey - add support for PON GEN3 base addresses

2022-04-25T01:25:12+00:00

Currently, PON address is read from the "reg" property. For PON GEN3, which starts with PMK8350, the "reg" property will have both the PON HLOS and PON PBS addesses defined. Add support so that all PON generations can be configured.

Input: pm8941-pwrkey - fix error message

2022-04-25T01:25:10+00:00

Currently, error message reads "failed to set debounce". However, code is attempting to read revision not set debounce. Fix this.

Input: pm8941-pwrkey - respect reboot_mode for warm reset

2021-10-17T04:31:07+00:00

On some devices, e.g. Sony Xperia M4 Aqua, warm reset is used to reboot device into bootloader and recovery mode. Instead of always doing hard reset, add a check on reboot_mode for possible warm reset.

Input: pm8941-pwrkey - fix comma vs semicolon issue

2021-07-24T00:37:14+00:00

There is absolutely no reason to use comma operator in this code, 2 separate statements make much more sense. Reviewed-by: Stephen Boyd Link: https://lore.kernel.org/r/YPsa1qCBn/SAmE5x@google.com Signed-off-by: Dmitry Torokhov

Input: pm8941-pwrkey - add support for PMK8350 PON_HLOS PMIC peripheral

2021-06-02T04:35:27+00:00

On Qualcomm Technologies, Inc. PMIC PMK8350, the PON peripheral is split into two peripherals: PON_HLOS and PON_PBS. The application processor only has write access to PON_HLOS which limits it to only receiving PON interrupts. Add support for the PMK8350 PON_HLOS peripheral so that its KPDPWR_N and RESIN_N interrupts can be used to detect key presses.

Input: remove dev_err() usage after platform_get_irq()

2019-08-14T17:49:01+00:00

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).
