[PATCH v3][for 4.17-rc3] cpufreq / CPPC: Set platform specific transition_delay_us

by Prashanth Prakash

Add support to specify platform specific transition_delay_us instead of using the transition delay derived from PCC. With commit "3d41386d556d: cpufreq: CPPC: Use transition_delay_us depending transition_latency" we are setting transition_delay_us directly and not applying the LATENCY_MULTIPLIER. With this on Qualcomm Centriq we can end up with a very high rate of frequency change requests when using schedutil governor (default rate_limit_us=10 compared to an earlier value of 10000). The PCC subspace describes the rate at which the platform can accept commands on the CPPC's PCC channel. This includes read and write command on the PCC channel that can be used for reasons other than frequency transitions. Moreover the same PCC subspace can be used by multiple freq domains and deriving transition_delay_us from it as we do now can be sub-optimal. Moreover if a platform does not use PCC for desired_perf register then there is no way to compute the transition latency or the delay_us. CPPC does not have a standard defined mechanism to get the transition rate or the latency at the moment. Given the above limitations, it is simpler to have a platform specific transition_delay_us and rely on PCC derived value only if a platform specific value is not available.

Revert f5a26acf0162 ("pinctrl: intel: Initialize GPIO properly when used through irqchip") from stable trees

by Mika Westerberg

Hi, It seems that commit f5a26acf0162 ("pinctrl: intel: Initialize GPIO properly when used through irqchip") can cause problems on some Skylake systems with Sunrisepoint PCH-H. Namely on certain systems it may turn the backlight PWM pin from native mode to GPIO which makes the screen blank during boot. There is more information here: https://bugzilla.redhat.com/show_bug.cgi?id=1543769 The actual reason is that GPIO numbering used in BIOS is using "Windows" numbers meaning that they don't match the hardware 1:1 and because of this a wrong pin (backlight PWM) is picked and switched to GPIO mode. There is a proper fix for this but since it has quite many dependencies on commits that cannot be considered stable material, I suggest we revert commit f5a26acf0162 from stable trees 4.9, 4.14 and 4.15 to prevent the backlight issue. Thanks!

[PATCH] ARM: dts: Fix NAS4220B pin config

by Linus Walleij

The DTS file for the NAS4220B had the pin config for the ethernet interface set to the pins in the SL3512 SoC while this system is using SL3516.

[PATCH 01/11] PM / Domains: Fix error path during attach in genpd

by Ulf Hansson

In case the PM domain fails to be powered on in genpd_dev_pm_attach(), it returns -EPROBE_DEFER, but keeping the device attached to its PM domain. This leads to problems when the next attempt to attach is re-tried. More precisely, in that situation an -EEXIST error code is returned, because the device already has its PM domain pointer assigned, from the first attempt. Now, because of the sloppy error handling by the existing callers of dev_pm_domain_attach(), probing is allowed to continue when -EEXIST is returned. However, in such case there are no guarantees that the PM domain is powered on by genpd, which may lead to hangs when buses/drivers tried to access their devices. Let's fix this behaviour, simply by detaching the device when powering on fails in genpd_dev_pm_attach().

patch "ARM: amba: Fix race condition with driver_override" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ARM: amba: Fix race condition with driver_override to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 6a7228d90d42bcacfe38786756ba62762b91c20a Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven <geert+renesas(a)glider.be> Date: Tue, 10 Apr 2018 15:21:44 +0200 Subject: ARM: amba: Fix race condition with driver_override The driver_override implementation is susceptible to a race condition when different threads are reading vs storing a different driver override. Add locking to avoid this race condition. Cfr. commits 6265539776a0810b ("driver core: platform: fix race condition with driver_override") and 9561475db680f714 ("PCI: Fix race condition with driver_override").
