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.

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: https://lore.kernel.org/lkml/20170222022929.10540-1-afaerber@suse.de/ Signed-off-by: Duje Mihanović 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 - Link to v9: https://lore.kernel.org/20240402-pxa1908-lkml-v9-0-25a003e83c6f@skole.hr Changes in v9: - Update trailers and rebase on v6.9-rc2, no changes - Link to v8: https://lore.kernel.org/20240110-pxa1908-lkml-v8-0-fea768a59474@skole.hr Changes in v8: - Drop SSPA patch - Drop broken-cd from eMMC node - Specify S-Boot hardcoded initramfs location in device tree - Add ARM PMU node - Correct inverted modem memory base and size - Update trailers - Rebase on next-20240110 - Link to v7: https://lore.kernel.org/20231102-pxa1908-lkml-v7-0-cabb1a0cb52b@skole.hr and https://lore.kernel.org/20231102152033.5511-1-duje.mihanovic@skole.hr Changes in v7: - Suppress SND_MMP_SOC_SSPA on ARM64 - Update trailers - Rebase on v6.6-rc7 - Link to v6: https://lore.kernel.org/r/20231010-pxa1908-lkml-v6-0-b2fe09240cf8@skole.hr Changes in v6: - Address maintainer comments: - Add "marvell,pxa1908-padconf" binding to pinctrl-single driver - Drop GPIO patch as it's been pulled - Update trailers - Rebase on v6.6-rc5 - Link to v5: https://lore.kernel.org/r/20230812-pxa1908-lkml-v5-0-a5d51937ee34@skole.hr Changes in v5: - Address maintainer comments: - Move *_NR_CLKS to clock driver from dt binding file - Allocate correct number of clocks for each block instead of blindly allocating 50 for each - Link to v4: https://lore.kernel.org/r/20230807-pxa1908-lkml-v4-0-cb387d73b452@skole.hr Changes in v4: -
