More Qualcomm driver updates for 6.3
The qcom_scm.h file is moved into firmware/qcom, to avoid having any Qualcomm-specific files directly in include/linux. Support for PMIC GLINK is introduced, which on newer Qualcomm platforms provides an interface to the firmware implementing battery management and USB Type-C handling. Together with the base driver comes the custom altmode support driver. SMD RPM gains support for IPQ9574, and socinfo is extended with support for revision 17 of the information format and soc_id for IPQ5332 and IPQ8064 are added. The qcom_stats is changes not to fail when not all parts are initialized. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmPmiz4VHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FMZ8QANXJEr7U2KX/yd4riBju6Btn0unl I8TR5XlaQAoBUbyp4yTcCUfCe0mEiNcE/YgJwzSKY3mNxc9vLhn1GgqdF+5RFTZw 0H8GBjUpQiRoCC2+pq3YCEisQ49HYXy9W3ys6t1Y3l8xUDLhw5CkeKOGQCqeBDX7 pCflPy7HFUQwPhGt7AOmpNj8+Kh4GnpJHF3D2ShAMFNOn4+l0v8Gh7zDw62FmhBg gjA7eS2aZS7KmqEJMAC4dEFdmhvvN+a80KaWNOOQn2sdLtD64pRW2hknxinPRN+t dGQKeD+VGFHLfxWO40Lv0nP8P/EWjXiZdhO8HXLmVjHC56G/MG8AW0BkvxW9jPAa QGlzY0TbEbi0MbbAnyCJTy6USGtVUZbEmfcZ8r3rUJX5xO8eszSjueD6fH/nKIgo hDIIG8nSLf5TCY+NJzGr8dKENiElsgsfdNAypoX6kpXCRUCXxkiKlWzy/3oywVcO bKm5xs76YNNaANFf46oO6kts7nrOcegyTAdvauFemy1Q3KSWQuFP4jNpcRvWnVMN 8/BlQ+a5uGofN/wwHS2CPmE1r8njEqlPc7wWNc0ugoRO4kAUtB2UldjjS/ZfaFvH BZiDDXhjScPj8lKk4kzGOb34W5AKkwFbTwSR1oN0ckW9UNDx51pNu72YlU8WLydV VHmzD9ndTkWSmp7W =+KgT -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmPqVbkACgkQmmx57+YA GNnlFRAAuaoe9/7kOAliVks4vkJ8284POk50kuS5llzNAP4BPsQIJakE6dOOiTY1 01qbvTlu5pK+f2ls+3WQYr5Rhgck4BUEFD+t9WcPtOpB1uq0puyWj3fwuErjDFJv S6nKp2P0tpru5VzQFPROyrBCw5Zlkc0U9FID4P1Ub5ulxxDWJ4ODb9Q+C9DtDxJo HuUGRnGPLmAJd4ymKzCtnqcg3gocFdrl9K+msFuJwAgdZ0xB893l3wyOFn2k97Uh 8m8WEI/NbCTfDEjag3+yx9Sl3rZhtav0EnlIqowBHQFvxFaBDnvW6H4QmNRugAog +kH1hVzojj35jDllwL07OJzdjqW497Z9i+MEGz45h/8FvvdqJ+71UTkOwr+vnWKu zuEzEfM+bB434UBCQihJ7emx7eCac3TP3Von/NigDDBIXDu8iqNgUNmB8eNyN+gJ Db1mdatG4TuSEqnzetX4XKLP3eydxG8lkEZDOcWlhRz8CSWx9KkBU7W+hVNCBLdV kdhjvZpb5cRcqc/KsS22hmB3HIoISGkLrBOvqs375+Sg9PFxBGst+q24kf9MEDFz ypj/CRiMzkNq8IBwGF003CVhDHmlloq2afQ7YX0w1sEE0XOCIDE0YWNNb9fcoTAC MeDL9R4VgfjR/8Bj7zgnYOMAt6hRoHXsZ1gtS29doIH5iLdTXVI= =8eLr -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-6.3-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers More Qualcomm driver updates for 6.3 The qcom_scm.h file is moved into firmware/qcom, to avoid having any Qualcomm-specific files directly in include/linux.

The PMIC GLINK service, running on a coprocessor on some modern Qualcomm
|

platforms and implement USB Type-C handling and battery management. This

binding describes the component in the OS used to communicate with the
|

firmware and connect it's resources to those described in the Devicetree,

particularly the USB Type-C controllers relationship with USB and DisplayPort
