![]() Core and userspace API: - The userspace API KFIFOs have been imoproved with locks that do not block interrupts. This makes us better at getting events to userspace without blocking or disturbing new events arriving in the same time. This was reviewed by the KFIFO maintainer Stefani. This is a generic improvement which paves the road for similar improvements in other subsystems. - We provide a new ioctl() for monitoring changes in the line information, such as when multiple clients are taking lines and giving them back, possibly reconfiguring them in the process: we can now monitor that and not get stuck with stale static information. - An example tool 'gpio-watch' is provided to showcase this functionality. - Timestamps for events are switched to ktime_get_ns() which is monotonic. We previously had a 'realtime' stamp which could move forward and *backward* in time, which probably would just cause silent bugs and weird behaviour. In the long run we see two relevant timestamps: ktime_get_ns() or the timestamp sometimes provided by the GPIO hardware itself, if that exists. - Device Tree overlay support for GPIO hogs. On systems that load overlays, these overlays can now contain hogs, and will then be respected. - Handle pin control interaction with nonexisting pin ranges in the GPIO library core instead of in the individual drivers. New drivers: - New driver for the Mellanox BlueField 2 GPIO controller. Driver improvements: - Introduce the BGPIOF_NO_SET_ON_INPUT flag to the generic MMIO GPIO library and use this flag in the MT7621 driver. - Texas Instruments OMAP CPU power management improvements, such as blocking of idle on pending GPIO interrupts. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEElDRnuGcz/wPCXQWMQRCzN7AZXXMFAl6IWUAACgkQQRCzN7AZ XXPReQ//WUHALqbLOL/DZR8kVyygVZXV8JC4jcuMQgX+Mvm1DQuGp1T8VPlG1wC7 vy5eTz3oPc+jAaHGQgGiSGdPRQtDkAW5+Wo4hzcHJ5ATlzT7cgNywK3Jk6+YlPlF CuhHB6aPEymQ45/GseUwEb5AuWWKS03P3XdOBj2IdDhuRHRfyjHi+31s0lh6bfNs kC2eP+VtddVqLbOdPE1GKjZi+Iq9ffFRmiNTduHbl3o6ZoE6WnMvn2wsC6zPpJr4 AM8zpj9JFUq1DYaQf8bJJLTm8lItcyyUUhq8oKUxBpecjWfhUYwEYHGxqWIk9fbM oyJ3zBlU0G7bc4gu1VG3cTacUf//BTmQG3iZNSSw9w17I1hOMX9wNJan22VkEbJD 8X+6AcgkldNwnAVWcVgg1lkfgdxlWURMYXl1uQPQZSj2SQL6gFcdkAhKwlgl8jOi RctUfZ69tD+4ul2b+MhL6BtIk16o2RIBJF53ESxrR4qftRZ3ywW4JQ/AwNoQalxM Xg8U3axFm8kitOzemVoXGr/AIee9KpcA4NK8yQLEPmSFgBaVzaVlP9Q7Klr7QGXg RvK45uRULrWnvSyoVY7Ox+ie1NiG8JAbaxKBxkV8n+z+gVMh82xcyQX+5SgWxwW0 dzeEx1B0mCW4WDAK29CcdQVE6m4K2u/fabhZq5IhgS1mQoTC894= =EFm/ -----END PGP SIGNATURE----- Merge tag 'gpio-v5.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO development for the v5.7 kernel cycle.
