This is a note to let you know that I've just added the patch titled pinctrl: qcom: sdm845: Enable dual edge errata to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: pinctrl-qcom-sdm845-enable-dual-edge-errata.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit f1c951732ed9d4633c66a16c751a498c4e61082e Author: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx> Date: Mon Nov 1 22:41:15 2021 -0500 pinctrl: qcom: sdm845: Enable dual edge errata [ Upstream commit 3a3a100473d2f6ebf9bdfe6efedd7e18de724388 ] It has been observed that dual edge triggered wakeirq GPIOs on SDM845 doesn't trigger interrupts on the falling edge. Enabling wakeirq_dual_edge_errata for SDM845 indicates that the PDC in SDM845 suffers from the same problem described, and worked around, by Doug in 'c3c0c2e18d94 ("pinctrl: qcom: Handle broken/missing PDC dual edge IRQs on sc7180")', so enable the workaround for SDM845 as well. The specific problem seen without this is that gpio-keys does not detect the falling edge of the LID gpio on the Lenovo Yoga C630 and as such consistently reports the LID as closed.
