+GPG Signed Releases
+-------------------
+
+i) Check if a release tag is GPG-signed or not
+
+if a tag is not signed, when you run ‘git tag -v <tag>’ command, you get the result as:
+
+$ git tag -v lts-v4.19.272-android_t-230316T041640Z
+object 7150c8b4efa2baf0bef3a3da3850d29715c6fcbb
+type commit
+tag lts-v4.19.272-android_t-230316T041640Z
+tagger sys_oak [email protected] 1679296599 -0700
+
+release Kernel 4.19 for android T Dessert
+error: no signature found
+
+You can see ‘error: no signature found’ if the tag is not signed
+
+If the tag is signed - please follow the below steps to get the public key and verify the tag -
+
+ii) Download public key
+
+Open https://keys.openpgp.org/, input Full Key ID (i.e., EB4D99E5113E284368955757F18D9D84E60D69E7), or,
+short Key ID (i.e., F18D9D84E60D69E7, the Last 16 digitals). or, the tagger email address(i.e., [email protected]), 
+Click ‘Search’, then you can download the pub key file (i.e., EB4D99E5113E284368955757F18D9D84E60D69E7.asc).
+The md5sum checksum is 40b0222665a5f6c70ca9d990b4014f43 for the pub key file:
+$ md5sum EB4D99E5113E284368955757F18D9D84E60D69E7.asc 
+40b0222665a5f6c70ca9d990b4014f43  EB4D99E5113E284368955757F18D9D84E60D69E7.asc
+
+Once your checksum is correct, please do next step.
+
+iii) Configure your Linux Environment and verify the GPG signature of a tag ( one time setup) 
+
+After you get the right pub key, please import it:
+$ gpg --import EB4D99E5113E284368955757F18D9D84E60D69E7.asc
+
+Now, when you check the tag GPG signature, you can see ‘Good signature’ with a WARNING:
+$ git tag -v lts-v4.19.282-android_t-230509T073627Z
+object 180df1199944ebd8928f320a1bd16c8a87dba2ed

+gpg: Signature made Fri 12 May 2023 12:07:37 AM EDT
+gpg:                using RSA key EB4D99E5113E284368955757F18D9D84E60D69E7
+gpg: Good signature from "sys_oak (NSWE) [email protected]" [unknown]
+gpg: WARNING: This key is not certified with a trusted signature!
+gpg:          There is no indication that the signature belongs to the owner.
+Primary key fingerprint: EB4D 99E5 113E 2843 6895  5757 F18D 9D84 E60D 69E7
+
+To deal with the WARNING, let the pub key be trusted, run ‘gpg --edit-key <key>’ to edit it ( one time setup)
+$ gpg --edit-key F18D9D84E60D69E7  
+input trust
+input 5
+input y
+input quit
+
+Now, when you check the tag GPG signature again , you can see ‘Good signature’ without warnings: 
+$ git tag -v lts-v4.19.282-android_t-230509T073627Z
+object 180df1199944ebd8928f320a1bd16c8a87dba2ed

+Subject: [PATCH 001/193] ASoC: Intel: Skylake: Relocate ipc structs to
+ appropriate header
+
+IPC related structs never belonged to topology domain, these are
+strictly part of DSP firmware communication interface. Relocate them.
+While at it, update skl_connector_node_id declaration to reflect changes
+made in firmware.
