Devicetree fixes for v6.2:
- Fix DT memory scanning for some MIPS boards when memory is not specified in DT - Redo CONFIG_CMDLINE* handling for missing /chosen node. The first attempt broke PS3 (and possibly other PPC platforms). - Fix constraints in QCom Soundwire schema -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEktVUI4SxYhzZyEuo+vtdtY28YcMFAmO5jqUACgkQ+vtdtY28 YcPxLQ//VIeelvp7U8HgdB13ZlWC1DXYTDZUgIev3R/sggws4swkCu5cZP3xbKnD 88uW9Lbv5sSSfAXdr3hbr3z4sHLilX5mSc/1QvaIDrS0eECeFAUu8Me5Rx/Om806 0k8/1OmCgCr0RFJgjtersfw3CFnOLAauxYIr4mGCD8kWnXMgKSK/JyiTDV3+g3U2 Y6IgR+Hn8zt8DB1LkrRZJis5LQT1AxFtEzfKUEa+j/xG4z+B1vg8wENsYDr+/s9+ LAq4QhrzAU/Ys+ZUF3HqkZxj6WR7aMq5MSBihs1AXjR772g+EY7Ob00hPdf2MdFz TEF0GFTHQjvzM2TGY+V4AWKLER5Oxq0AsT7n8qsnPCJBRrVp1EHpfQUfhpibB0GN TGQlskUWJW8ivjl54jX/wzJyx3ZlW4SmeD5c5RRaLOKHMhfIjsAdjQJIfNfPTE93 oCU9GniXhWoQDRCheqy5LIY7+hm1nuYra0WUzjp1rmfcZ2xia70ZKdbJe5gIAJVr fmefpzyxY5TeaZPIBsLysN9QURk3C5GXGyKHofcQsC4TCn3qgzNoSmYkESAjTtkW kUzNraoIhY92HN0jDfYD1/iGTeOzAYnL4kqILKIoNtBEQmyFZqxLUk6TX7Cm8QJU BZTPuxzmMJMFx88FB/nPdNlyQcELSjrTAfFMd5i7/WBuY3OTYIE= =qIdA -----END PGP SIGNATURE----- Merge tag 'devicetree-fixes-for-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull devicetree fixes from Rob Herring: - Fix DT memory scanning for some MIPS boards when memory is not specified in DT - Redo CONFIG_CMDLINE* handling for missing /chosen node.
