Unlike the previous revisions which are based on -rc tags, this revision is based on next-20240110 as it requires commits 67508b874844 ("ASoC: pxa: sspa: Don't select SND_ARM") and 6db359b5eef5 ("soc: pxa: ssp: fix casts") from the linux-next tree to compile successfully with allyesconfig/allmodconfig. USB works and the phone can boot a rootfs from an SD card, but there are some warnings in the dmesg: During SMP initialization: [ 0.006519] CPU features: SANITY CHECK: Unexpected variation in SYS_CNTFRQ_EL0.
