The gpio node in PMIC dts'es define access to multiple GPIOs. Most Qcom PMICs were already using the plural _gpios label to point to this node, but a few PMICs were left behind including the recently-pulled pm(i)8950. Rename it from *_gpio to *_gpios for pm6125, pm6150(l), pm8005, pm(i)8950, and pm(i)8998. Signed-off-by:

The framebuffer configuration for kumano griffin, written in kumano dtsi (which is overwritten in bahamut dts for its smaller panel) has to use a 1096x2560 configuration as this is what the panel (and framebuffer area) has been initialized to. Downstream userspace also has access to (and uses) this 2.5k mode by default, and only switches the panel to 4k when requested.

Now that we've added the `off-on-delay-us` for the touchpanel regulator, we can see that we're actually hitting that delay at bootup. I saw about 200 ms of delay. Let's avoid that delay by starting the regulator on. We'll only do this for eDP devices for the time being. NOTE: we _won't_ do this for homestar. Homestar's panel really likes to be power cycled. It's why the Linux driver for this panel has a pm_runtime_put_sync_suspend() when the panel is being unprepared but the normal panel-edp driver doesn't. It's also why this hardware has a separate power rail for eDP vs. touchscreen, unlike all the other trogdor boards. We won't start homestar's regulator on. While this could mean a slight delay on homestar, it is probably a _correct_ delay. The bootloader might have left the regulator on (it does so in dev and recovery modes), so if we turned the regulator off at probe time and we actually hit the delay then we were probably violating T12 in the panel spec.

In general, the timing diagrams for components specify a minimum time for power cycling the component. When we remove power from a device we need to let the device fully discharge and get to a quiescent state before applying power again. If we power a device on too soon then it might not have fully powered off and might be in a weird in-between / invalid state. eDP panels typically have a time that's at least 500 ms here. You can see that in Linux's panel-edp driver nearly every device specifies a "unprepare" time of at least 500 ms. This is a common minimum and the 500 ms is even in the example in the eDP spec. In Linux, the "panel-edp" driver enforces this delay for its own control of the regulator, but the "panel-edp" driver can't do anything about other control of the regulator (for instance, by the touchpanel driver). Let's add 500 ms as a board constraint for the regulator that's used for eDP/touchpanel on trogdor boards. If a given trogdor board stuffs only panels that can use a shorter time or stuff some panels that need a larger time then they can manually adjust this timing. We'll only do this minimum delay for trogdor devices with eDP (ones that use either bridge chip), not for devices with MIPI panels. MIPI panels could have similar constraints but the 500 ms isn't necessarily as standard and there are no known cases where this delay is needed. For most trogdor boards, this doesn't actually seem to affect anything when testing against shipping Linux. However, with pazqel360 it seems that this does make a difference. It seems that the touchscreen on this board _also_ needs some time for the regulator to discharge. That time is much less than 500 ms, so we'll just put the eDP panel 500 ms in there since the board constraint should be the "max" of the components. Signed-off-by:

On at least one board (pazquel360) the reset line for the touchscreen was scoped and found to take almost 2 ms to fall when we drove it low. This wasn't great because the Linux driver for the touchscreen (the elants_i2c driver) thinks it can do a 500 us reset pulse. If we bump the drive strength to 8 mA then the reset line went down in ~421 us. NOTE: we could apply this fix just for pazquel360, but: * Probably other trogdor devices have similar timings and it's just that nobody has noticed it before. * There are other trogdor boards using the same elan driver that tries to do 500 us reset pulses. * Bumping the drive strength to 8mA across the board won't hurt. This isn't a high speed signal or anything. Signed-off-by:

rpmcc used to rely on global clock lookup (and still does so for backwards compat reasons) of "xo_board", which was common back when we did not care about things like underscores in node names. Nowadays it expects to be fed a reference to the fixed clock. Satisfy that requirement to make sure rpm clock rates are not all stuck at zero.

In its current form, UFS did not even probe successfully - it failed when trying to set XO (ref_clk) to 300 MHz instead of doing so to the ICE clk. Moreover, the missing reg-names prevented ICE from working or being discovered at all. Fix both of these issues. As a sidenote, the log reveals that this SoC uses UFS ICE v3.1.0.

Sony ever so graciously provides GPIO line names in their downstream kernel (though sometimes they are not 100% accurate and you can judge that by simply looking at them and with what drivers they are used). Add these to the PDX213&214 DTSIs to better document the hardware. Diff between 223 and 224: pm8350b < gpio-line-names = "NC", /* GPIO_1 */ > gpio-line-names = "CAM_PWR_A_CS", /* GPIO_1 */ < "NC", > "CAM_PWR_LD_EN", pm8350c < "NC", > "WLC_TXPWR_EN", Which is due to different camera power wiring on 213 and lack of an additional SLG51000 PMIC on 214.

Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/Signed-off-by:Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by:
