interconnect changes for 6.4
This pull request contains the interconnect changes for the 6.4-rc1 merge window, which this time are mostly cleanups. Core changes: interconnect: Skip call into provider if initial bw is zero interconnect: Use of_property_present() for testing DT property presence interconnect: drop racy registration API interconnect: drop unused icc_link_destroy() interface Driver changes: interconnect: qcom: Drop obsolete dependency on COMPILE_TEST interconnect: qcom: drop obsolete OSM_L3/EPSS defines interconnect: qcom: osm-l3: drop unuserd header inclusion interconnect: qcom: rpm: drop bogus pm domain attach interconnect: qcom: rpm: make QoS INVALID default interconnect: qcom: rpm: Add support for specifying channel num interconnect: qcom: Sort kerneldoc entries dt-bindings: interconnect: OSM L3: Add SM6375 CPUCP compatible dt-bindings: interconnect: qcom,msm8998-bwmon: Resolve MSM8998 support Signed-off-by: Georgi Djakov <djakov@kernel.org> -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJkPP4dAAoJEIDQzArG2BZjaC8P/A8KlodPtmdjE6fJFsQFsDGR fjMXLnMiIafTpZ/LNwqKpmqwjJXMHVqRc+39/st3PzE5Xx3vyAbvoIExyn3LPWPJ u8g0uuLZBB24UdXvlOdwLf0y5gi1SGgFMdQr+3d3BMddCgJIL2q/cmBG2oVpsBYD jnn6+ghgdj01O6ewr/4ZlcwBnqeA6b7HA7Mfrae/YyNmRi7eaKFsczgZtD7TZCY6 dWI+1Ee3QPo+XS6wsrZKuqFuJ4f+7ipOSkU7fcke6ab7a5IUFW2979ozvyh6JslK j/K3IePjh/cNFBtvuD3mw+M1Kodkmgx4W0jmXCZBRRPvD/1Vk0mGMwpokxpuy6Vi dlLw7ciVrogB7EDiij9PiDAsFNYlwBy1m/miwKesr1zd0Hmeyf69QbTpIM3QB4SP nAShm8XZwMg6m4QfI3ToBzt5hmU9Or2OL/5vN2k+EQMeT682g9F3RuHkyGhZKcGQ wFyHXNHJa2gYPGPF+EhwLXeCmSwrqVUL5a1s4pOD6X+VaEH+GuzxeCEvM3jAosNL qB5GD06ka7lIk7vid38dqiw9663vgtbOA8M8GF4tyAsNvnq2L5lwQ+UbrR42mveP YCdJwatPC+S0er56p6JjbGuxAEq8MkCurw813QNQmBxsYLq4BajQboM63XHoLHP7 0YOKlzGhnIaV6V/8hkoS =By6c -----END PGP SIGNATURE----- Merge tag 'icc-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/djakov/icc into char-misc-next Georgi writes: interconnect changes for 6.4 This pull request contains the interconnect changes for the 6.4-rc1 merge window, which this time are mostly cleanups.
