Legend
In Linux mainline since version x
Nobody works on it, but it should be compatible with already done drivers
Somebody works on it
No support, nobody works on it
support impossible
Status is unknown/to be completed

Work In Progress

  • xRX350 Clocks, Serial [v2] MIPS: intel: add initial support for Intel MIPS

Planed for 5.13

  • LGM DMA [v11] Add Intel LGM SoC DMA support

Planed for 5.11

  • LGM NAND [v17] mtd: rawnand: Add NAND controller support on Intel LGM SoC

Planed for 5.10

  • xRX300 xRX330
    • GPHY Clocks [] MIPS: lantiq: add missing GPHY clock aliases for ar10 and grx390
    • GPHY LEDs [] gpio: stp-xway: automatically drive GPHY leds on ar10 and grx390

Merged into 5.6
