[PATCH] ALSA: hda/hdmi - add a parameter to let users decide if checking the eld_valid

by Hui Wang

With the commit 7f641e26a6df ("ALSA: hda/hdmi - Consider eld_valid when reporting jack event"), the driver checks eld_valid before reporting Jack state, this fixes the 4 HDMI/DP audio devices issue. But recently some users complained that the hdmi audio on their machines couldn't work anymore with this commit. On their machines, the monitor_present is 1 while the eld_valid is 0 when plugging a monitor, and the hdmi audio could work even the eld_valid is 0. To make the hdmi audio work again on those machines, adding a module parameter, if usrs want to skip the checking eld_valid, they could set checking_eld_valid=0 when loading the module. And this parameter only applies to sense_via_verbs, for those getting eld via component, no need to apply this parameter since it is impossible that present is 1 while eld_valid is 0.

[v2 PATCH] PCI: Do not use bus number zero from EA capability

by sundeep.lkml＠gmail.com

From: Subbaraya Sundeep <sbhatta(a)marvell.com> As per the spec, "Enhanced Allocation (EA) for Memory and I/O Resources" ECN, approved 23 October 2014, sec 6.9.1.2, fixed bus numbers of a bridge must be zero when no function that uses EA is located behind it. Hence assign bus numbers normally instead of assigning zeroes from EA capability. Failing to do this and using zeroes from EA would make the bridges non-functional.

patch "usb: dwc2: use a longer core rest timeout in dwc2_core_reset()" added to usb-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: dwc2: use a longer core rest timeout in dwc2_core_reset() to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-testing 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 be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 6689f0f4bb14e50917ba42eb9b41c25e0184970c Mon Sep 17 00:00:00 2001 From: Mathias Kresin <dev(a)kresin.me> Date: Sun, 7 Jul 2019 16:22:01 +0200 Subject: usb: dwc2: use a longer core rest timeout in dwc2_core_reset() Testing on different generations of Lantiq MIPS SoC based boards, showed that it takes up to 1500 us until the core reset bit is cleared. The driver from the vendor SDK (ifxhcd) uses a 1 second timeout. Use the same timeout to fix wrong hang detections and make the driver work for Lantiq MIPS SoCs. At least till kernel 4.14 the hanging reset only caused a warning but the driver was probed successful. With kernel 4.19 errors out with EBUSY.

[PATCH] ARM: dts: omap3-tao3530: Fix incorrect MMC card detection GPIO polarity

by Jarkko Nikula

The MMC card detection GPIO polarity is active low on TAO3530, like in many other similar boards. Now the card is not detected and it is unable to mount rootfs from an SD card. Fix this by using the correct polarity. This incorrect polarity was defined already in the commit 30d95c6d7092 ("ARM: dts: omap3: Add Technexion TAO3530 SOM omap3-tao3530.dtsi") in v3.18 kernel and later changed to use defined GPIO constants in v4.4 kernel by the commit 3a637e008e54 ("ARM: dts: Use defined GPIO constants in flags cell for OMAP2+ boards"). While the latter commit did not introduce the issue I'm marking it with Fixes tag due the v4.4 kernels still being maintained.
