platform/x86: touchscreen_dmi: Add info for the Chuwi Hi10 Pro (CWI529) tablet

2021-06-03T07:00:45Z

[ Upstream commit e68671e9e1275dfdda333c3e83b6d28963af16b6 ] Add touchscreen info for the Chuwi Hi10 Pro (CWI529) tablet. This includes info for getting the firmware directly from the UEFI, so that the user does not need to manually install the firmware in /lib/firmware/silead. This change will make the touchscreen on these devices work OOTB, without requiring any manual setup.

platform/x86: hp_accel: Avoid invoking _INI to speed up resume

2021-06-03T07:00:39Z

[ Upstream commit 79d341e26ebcdbc622348aaaab6f8f89b6fdb25f ] hp_accel can take almost two seconds to resume on some HP laptops. The bottleneck is on evaluating _INI, which is only needed to run once. Resolve the issue by only invoking _INI when it's necessary. Namely, on probe and on hibernation restore.

platform/x86: dell-smbios-wmi: Fix oops on rmmod dell_smbios

[ Upstream commit 3a53587423d25c87af4b4126a806a0575104b45e ] init_dell_smbios_wmi() only registers the dell_smbios_wmi_driver on systems where the Dell WMI interface is supported.

platform/x86: intel_int0002_vgpio: Only call enable_irq_wake() when using s2idle

2021-05-26T10:06:49Z

[ Upstream commit b68e182a3062e326b891f47152a3a1b84abccf0f ] Commit 871f1f2bcb01 ("platform/x86: intel_int0002_vgpio: Only implement irq_set_wake on Bay Trail") stopped passing irq_set_wake requests on to the parents IRQ because this was breaking suspend (causing immediate wakeups) on an Asus E202SA. This workaround for the Asus E202SA is causing wakeup by USB keyboard to not work on other devices with Airmont CPU cores such as the Medion Akoya E1239T. In hindsight the problem with the Asus E202SA has nothing to do with Silvermont vs Airmont CPU cores, so the differentiation between the 2 types of CPU cores introduced by the previous fix is wrong. The real issue at hand is s2idle vs S3 suspend where the suspend is mostly handled by firmware. The parent IRQ for the INT0002 device is shared with the ACPI SCI and the real problem is that the INT0002 code should not be messing with the wakeup settings of that IRQ when suspend/resume is being handled by the firmware. Note that on systems which support both s2idle and S3 suspend, which suspend method to use can be changed at runtime. This patch fixes both the Asus E202SA spurious wakeups issue as well as the wakeup by USB keyboard not working on the Medion Akoya E1239T issue. These are both fixed by replacing the old workaround with delaying the enable_irq_wake(parent_irq) call till system-suspend time and protecting it with a !pm_suspend_via_firmware() check so that we still do not call it on devices using firmware-based (S3) suspend such as the Asus E202SA. Note rather then adding #ifdef CONFIG_PM_SLEEP, this commit simply adds a "depends on PM_SLEEP" to the Kconfig since this drivers whole purpose is to deal with wakeup events, so using it without CONFIG_PM_SLEEP makes no sense.

platform/mellanox: mlxbf-tmfifo: Fix a memory barrier issue

2021-05-26T10:06:49Z

[ Upstream commit 1c0e5701c5e792c090aef0e5b9b8923c334d9324 ] The virtio framework uses wmb() when updating avail->idx. It guarantees the write order, but not necessarily loading order for the code accessing the memory. This commit adds a load barrier after reading the avail->idx to make sure all the data in the descriptor is visible. It also adds a barrier when returning the packet to virtio framework to make sure read/writes are visible to the virtio code.

platform/x86: pmc_atom: Match all Beckhoff Automation baytrail boards with critclk_systems DMI table

2021-05-14T07:50:20Z

[ Upstream commit d21e5abd3a005253eb033090aab2e43bce090d89 ] pmc_plt_clk* clocks are used for ethernet controllers, so need to stay turned on. This adds the affected board family to critclk_systems DMI table, so the clocks are marked as CLK_CRITICAL and not turned off. This replaces the previously listed boards with a match for the whole device family CBxx63. CBxx63 matches only baytrail devices. There are new affected boards that would otherwise need to be listed. There are unaffected boards in the family, but having the clocks turned on is not an issue.
