This adds some silicon blocks to the BCM6846 DTSI file and adds a device tree for the Genexis XG6846B device that make use of it. This is mainly so as to get this off my hard drive and share the basics with others who want to work on the BCM6846. I think most of the DTSI changes can be just copied verbatim to the rest of the BCMBCA family (maybe extracted into a common bcbca.dtsi?) but let's think about that later. This will do for now. The XG6846B device tree uses the new shift register bits property of the BCM63138 LEDs, which is ACKed by the DT maintainers albeit not yet merged in the LED tree. Signed-off-by: Linus Walleij <linus.walleij@xxxxxxxxxx> --- Changes in v3: - Fix the MDIO size-cells and address-cells, the <0> and <1> were switched around. - Defined, and made sure the ngpios property was accepted to the GPIO tree before proceeding to use it. See: https://lore.kernel.org/linux-gpio/20241017-gpio-ngpios-v2-1-cecfdb38d40e@xxxxxxxxxx/ - Link to v2: https://lore.kernel.org/r/20241016-genexis-xg6846b-base-v2-0-6a7cc2ee57eb@xxxxxxxxxx Changes in v2: - Use the new "brcm,bcm6846-mdio" compatible for the MDIO block. (Merged to the netdev tree). - Add the ARM PrimeCell PL081 DMA controller block. - Link to v1: https://lore.kernel.org/r/20241011-genexis-xg6846b-base-v1-0-f04d6f6f93ce@xxxxxxxxxx --- Linus Walleij (9): ARM: dts: bcm6846: Add iproc rng ARM: dts: bcm6846: Enable watchdog ARM: dts: bcm6846: Add GPIO blocks ARM: dts: bcm6846: Add MDIO control block ARM: dts: bcm6846: Add LED controller ARM: dts: bcm6846: Add ARM PL081 DMA block dt-bindings: vendor-prefixes: Add Genexis dt-bindings: arm: bcmbca: Add Genexis XG6846B ARM: dts: broadcom: Add Genexis XG6846B DTS file .../devicetree/bindings/arm/bcm/brcm,bcmbca.yaml | 1 + .../devicetree/bindings/vendor-prefixes.yaml | 2 + arch/arm/boot/dts/broadcom/Makefile | 1 + .../boot/dts/broadcom/bcm6846-genexis-xg6846b.dts | 244 +++++++++++++++++++++ arch/arm/boot/dts/broadcom/bcm6846.dtsi | 120 ++++++++++ 5 files changed, 368 insertions(+) --- base-commit: 9852d85ec9d492ebef56dc5f229416c925758edc change-id: 20241010-genexis-xg6846b-base-ef3fbec0be01 Best regards, -- Linus Walleij <linus.walleij@xxxxxxxxxx>
