Sync up with mainline to bring in xpad controller changes.

Input: snvs_pwrkey - support power-off-time-sec

2025-05-01T04:03:14Z

The power-off time is configured in LPCR[17:16] BTN_PRESS_TIME: * b00: 5 seconds (SoC default) * b01: 10 seconds * b10: 15 seconds * b11: PMIC is not disabled Signed-off-by: Ian Ray Link: https://lore.kernel.org/r/20250315093455.1100-3-ian.ray@gehealthcare.com Signed-off-by: Dmitry Torokhov

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12Z

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

Input: snvs_pwrkey - use devm_clk_get_optional_enabled()

2024-08-31T22:25:05Z

Switch to using devm_clk_get_optional_enabled() helper instead of acquiring the clock with devm_clk_get_optional(), enabling it, and defining and installing a custom devm action to call clk_disable().

Input: snvs_pwrkey - fix SNVS_HPVIDR1 register address

2022-09-27T14:18:30Z

Both i.MX6 and i.MX8 reference manuals list 0xBF8 as SNVS_HPVIDR1 (chapters 57.9 and 6.4.5 respectively). Without this, trying to read the revision number results in 0 on all revisions, causing the i.MX6 quirk to apply on all platforms, which in turn causes the driver to synthesise power button release events instead of passing the real one as they happen even on platforms like i.MX8 where that's not wanted.

Input: snvs_pwrkey - add clk handling

2021-10-16T05:11:01Z

On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an associated clock. Accessing the registers requires that this clock is enabled. Binding the driver on at least i.MX7S and i.MX8MP while not having the clock enabled results in a complete hang of the machine. (This usually only happens if snvs_pwrkey is built as a module and the rtc-snvs driver isn't already bound because at bootup the required clk is on and only gets disabled when the clk framework disables unused clks late during boot.) This completes the fix in commit 135be16d3505 ("ARM: dts: imx7s: add snvs clock to pwrkey").

Input: snvs_pwrkey - remove gratuitous NULL initializers

2019-12-05T01:56:55Z

Gratuitous NULL initializers rarely help and often prevent compiler from warning about using uninitialized variable. Let's remove them. Reviewed-by: Anson Huang Link: https://lore.kernel.org/r/20191125211407.GA97812@dtor-ws Signed-off-by: Dmitry Torokhov

Input: snvs_pwrkey - send key events for i.MX6 S, DL and Q

2019-11-25T21:32:11Z

The first generation i.MX6 processors does not send an interrupt when the power key is pressed. It sends a power down request interrupt if the key is released before a hard shutdown (5 second press). This should allow software to bring down the SoC safely. For this driver to work as a regular power key with the older SoCs, we need to send a keypress AND release when we get the power down request irq.

Input: remove dev_err() usage after platform_get_irq()

2019-08-14T17:49:01Z

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).
