Pull SoC update from Arnd Bergmann: "Convert ep93xx to devicetree This concludes a long journey towards replacing the old board files with devictree description on the Cirrus Logic EP93xx platform. Nikita Shubin has been working on this for a long time, for details see the last post on https://lore.kernel.org/lkml/20240909-ep93xx-v12-0-e86ab2423d4b@maquefel.me/" * tag 'soc-ep93xx-dt-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (47 commits) dt-bindings: gpio: ep9301: Add missing "#interrupt-cells" to examples MAINTAINERS: Update EP93XX ARM ARCHITECTURE maintainer soc: ep93xx: drop reference to removed EP93XX_SOC_COMMON config net: cirrus: use u8 for addr to calm down sparse dmaengine: cirrus: use snprintf() to calm down gcc 13.3.0 dmaengine: ep93xx: Fix a NULL vs IS_ERR() check in probe() pinctrl: ep93xx: Fix raster pins typo spi: ep93xx: update kerneldoc comments for ep93xx_spi clk: ep93xx: Fix off by one in ep93xx_div_recalc_rate() clk: ep93xx: add module license dmaengine: cirrus: remove platform code ASoC: cirrus: edb93xx: Delete driver ARM: ep93xx: soc: drop defines ARM: ep93xx: delete all boardfiles ata: pata_ep93xx: remove legacy pinctrl use pwm: ep93xx: drop legacy pinctrl ARM: ep93xx: DT for the Cirrus ep93xx SoC platforms ARM: dts: ep93xx: Add EDB9302 DT ARM: dts: ep93xx: add ts7250 board ARM: dts: add Cirrus EP93XX SoC .dtsi ...
