This patch add dts support for NAND flash controller of Hisilicon Soc Hip04 I resend this patch with new E-mail address in signed-off-by. Changes in v3: - Change E-mail address in signed-off-by to "wangzhou1 at hisilicon.com" Changes in v2: - Base on v3.19-rc1 - Use nand-ecc-strength, nand-ecc-step-size to replace hisi,nand-ecc-bits Changes in v1: - Move partition and other board related information into board dts file: hip04-d01.dts Signed-off-by: Zhou Wang <wangzhou1@hisilicon.com> --- arch/arm/boot/dts/hip04-d01.dts | 27 +++++++++++++++++++++++++++ arch/arm/boot/dts/hip04.dtsi | 7 +++++++ 2 files changed, 34 insertions(+)
