Hello,
This series adds initial support for the Marvell PXA1908 SoC and
"samsung,coreprimevelte", a smartphone using the SoC.
USB works and the phone can boot a rootfs from an SD card, but there are
some warnings in the dmesg:
During SMP initialization:

A 3.14 based Marvell tree is available on GitHub
acorn-marvell/brillo_pxa_kernel, and a Samsung one on GitHub
CoderCharmander/g361f-kernel.
Andreas Färber attempted to upstream support for this SoC in 2017:

Changes in v10:
- Update trailers
- Rebase on v6.9-rc5
- Clock driver changes:
- Add a couple of forgotten clocks in APBC
- The clocks are thermal_clk, ipc_clk, ssp0_clk, ssp2_clk and swjtag
- The IDs and register offsets were already present, but I forgot to
actually register them
- Split each controller block into own file
- Drop unneeded -of in clock driver filenames
- Simplify struct pxa1908_clk_unit
- Convert to platform driver
- Add module metadata
- DTS changes:
- Properly name pinctrl nodes
- Drop pinctrl #size-cells, #address-cells, ranges and #gpio-size-cells
- Fix pinctrl input-schmitt configuration
