The major part of the rpmsg changes for v5.18 relates to improvements in the rpmsg char driver, which now allow automatically attaching to rpmsg channels as well as initiating new communication channels from the Linux side. The SMD driver is moved to arch_initcall with the purpose of registering root clocks earlier during boot. Also in the SMD driver, a workaround for the resource power management (RPM) channel is introduced to resolve an issue where both the RPM and Linux side waits for the other to close the communication established by the bootloader - this unblocks support for clocks and regulators on some older Qualcomm platforms. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmJDwecbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3F3pkP/3+rM9Q6e+VnH05J9Irm wlq8ExFg1o68YG93LfvSiVXIssJ68bXvGW9N/JDpUE8LxxAV9jzmrs1h2He9NrFI qwgjr4EKpOQVKi9McPd5KLf/igPxG1TPgM0K8qJJB3y7moICdfXzxdkWQhPUmM9q WaIS/Tx40fq4mGher2dM6oeb8WaOu6uEWTHDFECvJAmvh9VE/1VOG+XkEccgm2SH vDr0BWErKn464yi1v/s7F3SsLXc/Rz4Wn0NhKVLG8jPTwqLA83yEpDOsAO6z7BrW zf/3pmlsnjgiBHWpET4JjqN/7R+ZjHeFWpFTf9kRmQE9eywY7meEiI25Dt5ixvsL /+NHYchcTtTbM11J6Zjpk6D2xbGotfU8NkNffJ1Q4uvI9HURhrDBaicCacDFjraJ t6WdK5sNpVPugcS2uqXmHguWXr2+1oGwPpUGO4hsNwktmnRhxbTootY3lIt4U39z SBgqWBdMpjZ9D5vnrrIREWuwU2O96Hot/TTTQk1m4qOIEzc0pr+k0RfkuHJs1/8s YMNmT6XviHzXpivw0Tc6ksrVYx4wknblWvIiN1NWjKsU2AAm3mmLdK8Mgy7nm4rm lR6235SBiMJt3cpva8rCNXH9InTBOj1SwN80YdCmxg1xZAsyAWBS6JwYzS5BGgtb pQjlE5SsQ6qMzwDE6SUYg4NV =rqWc -----END PGP SIGNATURE----- Merge tag 'rpmsg-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull rpmsg updates from Bjorn Andersson: "The major part of the rpmsg changes for v5.18 relates to improvements in the rpmsg char driver, which now allow automatically attaching to rpmsg channels as well as initiating new communication channels from the Linux side.
