This adds the NAND flash chip description for a standard chip found connected to this SoC. This makes use of generic Broadcom NAND driver with the iProc interface. Signed-off-by: Hauke Mehrtens <hauke@xxxxxxxxxx> --- changes since RFC: * remove linux,part-probe, there are still discussion about how this binding should look like * always activate the nand driver * put the description of the nand chip into an own file * do not remove the IRQ number from the bcma entry This is based on Broadcom stblinux branch bcm/dts Florian can you take this. arch/arm/boot/dts/bcm4708-asus-rt-ac56u.dts | 1 + arch/arm/boot/dts/bcm4708-asus-rt-ac68u.dts | 1 + arch/arm/boot/dts/bcm4708-buffalo-wzr-1750dhp.dts | 1 + arch/arm/boot/dts/bcm4708-luxul-xwc-1000.dts | 9 +++----- arch/arm/boot/dts/bcm4708-netgear-r6250.dts | 1 + arch/arm/boot/dts/bcm4708-netgear-r6300-v2.dts | 1 + arch/arm/boot/dts/bcm4708-smartrg-sr400ac.dts | 1 + arch/arm/boot/dts/bcm47081-asus-rt-n18u.dts | 1 + arch/arm/boot/dts/bcm47081-buffalo-wzr-600dhp2.dts | 1 + arch/arm/boot/dts/bcm47081-buffalo-wzr-900dhp.dts | 1 + arch/arm/boot/dts/bcm4709-buffalo-wxr-1900dhp.dts | 1 + arch/arm/boot/dts/bcm4709-netgear-r8000.dts | 1 + arch/arm/boot/dts/bcm5301x-nand-cs0-bch8.dtsi | 24 ++++++++++++++++++++++ arch/arm/boot/dts/bcm5301x.dtsi | 12 +++++++++++ 14 files changed, 50 insertions(+), 6 deletions(-) create mode 100644 arch/arm/boot/dts/bcm5301x-nand-cs0-bch8.dtsi diff --git a/arch/arm/boot/dts/bcm4708-asus-rt-ac56u.dts b/arch/arm/boot/dts/bcm4708-asus-rt-ac56u.dts index 71cff8d..112a5a8 100644 --- a/arch/arm/boot/dts/bcm4708-asus-rt-ac56u.dts +++ b/arch/arm/boot/dts/bcm4708-asus-rt-ac56u.dts @@ -10,6 +10,7 @@ /dts-v1/;
