The mic on this boards also needs micbias to be enabled, on some boards micbias1 is used and on others micbias2, so we enable both. This commit adds a new "Int Analog Mic" DAPM widget for this, so that we do not end up enabling micbias on boards with a digital mic which uses the already present "Int Mic" widget. Some existing UCM files already refer to "Int Mic" for their "Internal Analog Microphones" SectionDevice, but these don't work anyways since they enable the RECMIX BST1 Switch instead of the BST2 switch.

Patch "ACPI / video: Default lcd_only to true on Win8-ready and newer machines" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ACPI / video: Default lcd_only to true on Win8-ready and newer machines to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: acpi-video-default-lcd_only-to-true-on-win8-ready-and-newer-machines.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Mon Apr 9 13:58:16 CEST 2018 From: Hans de Goede <hdegoede(a)redhat.com> Date: Sat, 23 Dec 2017 19:41:47 +0100 Subject: ACPI / video: Default lcd_only to true on Win8-ready and newer machines From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit 5928c281524fe451114e04f1dfa11246a37e859f ] We're seeing a lot of bogus backlight interfaces on newer machines without a LCD such as desktops, servers and HDMI sticks. This causes userspace to show a non-functional brightness slider in e.g. the GNOME3 system menu, which is undesirable. And, in general, we should simply just not register a non functional backlight interface. Checking the LCD flag causes the bogus acpi_video backlight interfaces to go away (on the machines this was tested on). This change sets the lcd_only option by default on any machines which are Win8-ready, to fix this. This is not entirely without a risk of regressions, but video_detect.c already prefers native-backlight interfaces over the acpi_video one on Win8-ready machines, calling acpi_video_unregister_backlight() as soon as a native interface shows up. This is done because the ACPI backlight interface often is broken on Win8-ready machines, because win8 does not seem to actually use it. So in practice we already end up not registering the ACPI backlight interface on (most) Win8-ready machines with a LCD panel, thus this change does not change anything for (most) machines with a LCD panel and on machines without a LCD panel we actually don't want to register any backlight interfaces. This has been tested on the following machines and fixes a bogus backlight interface showing up there: - Desktop with an Asrock B150M Pro4S/D3 m.b. using i5-6500 builtin gfx - Intel Compute Stick STK1AW32SC - Meegopad T08 HDMI stick Bogus backlight interfaces have also been reported on: - Desktop with Asus H87I-Plus m.b. - Desktop with ASRock B75M-ITX m.b. - Desktop with Gigabyte Z87-D3HP m.b. - Dell PowerEdge T20 desktop Link: https://bugzilla.redhat.com/show_bug.cgi?id=1097436 Link: https://bugzilla.redhat.com/show_bug.cgi?id=1133327 Link: https://bugzilla.redhat.com/show_bug.cgi?id=1133329 Link: https://bugzilla.redhat.com/show_bug.cgi?id=1133646 Signed-off-by: Hans de Goede <hdegoede(a)redhat.com> Signed-off-by: Rafael J.

From: Rodrigo Vivi <rodrigo.vivi(a)intel.com> commit 6e3322c226f15bc1838007f5a75566f1482b8e40 upstream. If the table result is out of bounds on the array map there is something really wrong with VBT pin so we don't return that vbt_pin, but only return 0 instead. This basically reverts commit 'a8e6f3888b05 ("drm/i915/cnp: Ignore VBT request for know invalid DDC pin.")' Also this properly fixes commit 9c3b2689d01f ("drm/i915/cnl: Map VBT DDC Pin to BSpec DDC Pin.") v2: Do in a way that we don't break other platforms. (Jani) v3: Keep debug message (Jani) v4: Don't mess with 0 mapping was noticed by Jani and addressed with a simple solution suggested by Lucas that makes this even simpler.

According to the devicetree binding the shutdown and device wake GPIOs are optional. Since commit 3e81a4ca51a1 ("Bluetooth: hci_bcm: Mandate presence of shutdown and device wake GPIO") this driver won't probe anymore on Raspberry Pi 3 and Zero W (no device wake GPIO connected).
