From: Linus Torvalds Date: Sun, 5 Jun 2022 16:12:28 +0000 (-0700) Subject: Merge tag 'hte/for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra... X-Git-Tag: v5.19-rc1~16 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=2981436374177f78539b026ce5bcbab8c251818e;p=linux-block.git Merge tag 'hte/for-5.19-rc1' of git://git./linux/kernel/git/tegra/linux Pull hardware timestamping subsystem from Thierry Reding: "This contains the new HTE (hardware timestamping engine) subsystem that has been in the works for a couple of months now. The infrastructure provided allows for drivers to register as hardware timestamp providers, while consumers will be able to request events that they are interested in (such as GPIOs and IRQs) to be timestamped by the hardware providers. Note that this currently supports only one provider, but there seems to be enough interest in this functionality and we expect to see more drivers added once this is merged" [ Linus Walleij mentions the Intel PMC in the Elkhart and Tiger Lake platforms as another future timestamp provider ] * tag 'hte/for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: dt-bindings: timestamp: Correct id path dt-bindings: Renamed hte directory to timestamp hte: Uninitialized variable in hte_ts_get() hte: Fix off by one in hte_push_ts_ns() hte: Fix possible use-after-free in tegra_hte_test_remove() hte: Remove unused including MAINTAINERS: Add HTE Subsystem hte: Add Tegra HTE test driver tools: gpio: Add new hardware clock type gpiolib: cdev: Add hardware timestamp clock type gpio: tegra186: Add HTE support gpiolib: Add HTE support dt-bindings: Add HTE bindings hte: Add Tegra194 HTE kernel provider drivers: Add hardware timestamp engine (HTE) subsystem Documentation: Add HTE subsystem guide --- 2981436374177f78539b026ce5bcbab8c251818e diff --cc Documentation/index.rst index 67036a05b771,1987481866e1..8f9be0e658b4 --- a/Documentation/index.rst +++ b/Documentation/index.rst @@@ -136,7 -137,9 +136,8 @@@ needed) misc-devices/index scheduler/index mhi/index - tty/index peci/index + hte/index Architecture-agnostic documentation ----------------------------------- diff --cc MAINTAINERS index 76c221313a43,5feb95e67f0b..20bdf22601c3 --- a/MAINTAINERS +++ b/MAINTAINERS @@@ -9077,8 -8999,16 +9077,16 @@@ L: linux-input@vger.kernel.or S: Maintained F: drivers/input/touchscreen/htcpen.c + HTE SUBSYSTEM + M: Dipen Patel + S: Maintained + F: Documentation/devicetree/bindings/timestamp/ + F: Documentation/hte/ + F: drivers/hte/ + F: include/linux/hte.h + HTS221 TEMPERATURE-HUMIDITY IIO DRIVER -M: Lorenzo Bianconi +M: Lorenzo Bianconi L: linux-iio@vger.kernel.org S: Maintained W: http://www.st.com/
