With CONFIG_DMA_BOUNCE_UNALIGNED_KMALLOC enabled, the arm64 kernel still
allocates the default SWIOTLB buffer (64MB) even if ZONE_DMA is disabled
or all the RAM fits into this zone. However, this potentially wastes a
non-negligible amount of memory on platforms with little RAM.
Reduce the SWIOTLB size to 1MB per 1GB of RAM if only needed for
kmalloc() buffer bouncing.
rk322x has peripheral mode that is not working
really well, add various non-upstream patches
and timing adjustments that makes things a bit
more usable (mass storage and ethernet works,
uac isn't)
* merge patches from rockchip and rk322x families for current and edge
kernels
* adjust patches for tinkerboard to remove some cruft and overclocking
* rework kernel configs
* fix rk322x dmc to avoid lockup on rk3288
* migrate rockchip-6.6 into patch series, rename all patches with
more understandable names
* add gen-series.sh script in tools directory (it is a naive tool to
create patch series when you don't want to rebase everything)
