Please let me know what you think. Still works with the Rockbox player. Changes since v1: * rebased to linux-next (USB device patch already accepted) * moved pinmux to a separate node for CPLD on the demo board Wolfram Sang (2): ARM: dts: renesas: r9a06g032-rzn1d400-db: add pinmux for the CPLD ARM: dts: renesas: r9a06g032-rzn1d400-eb: enable USB host port arch/arm/boot/dts/renesas/r9a06g032-rzn1d400-db.dts | 10 ++++++++++ arch/arm/boot/dts/renesas/r9a06g032-rzn1d400-eb.dts | 4 ++++ 2 files changed, 14 insertions(+) -- 2.47.2 ^ permalink raw reply [flat|nested] 5+ messages in thread
