Hi, Rob Thank you for your attention ,it's the new version. The bellow is no use, so I'll remove it next patch.
+ freq-table-hz = <0 0>, <0 0>;
In the new version, we remove some no use codes in the driver; And taking into account the our next hi3670 platform, some of the public functions in the drive are extracted. In addition: 1) we do not have a single area that controls PHY as Qualcomm, so "phy_clk" remains the same. 2）"rst", "assert" is not generic and related with our soc implementation, So it's kept and there's no change. -----邮件原件----- 发件人: Rob Herring [mailto:robh@kernel.org] 发送时间: 2017年12月8日 7:36 收件人: liwei (CM) 抄送: mark.rutland@arm.com; xuwei (O); catalin.marinas@arm.com; will.deacon@arm.com; vinholikatti@gmail.com; jejb@linux.vnet.ibm.com; martin.petersen@oracle.com; khilman@baylibre.com; arnd@arndb.de; gregory.clement@free-electrons.com; thomas.petazzoni@free-electrons.com; yamada.masahiro@socionext.com; riku.voipio@linaro.org; treding@nvidia.com; krzk@kernel.org; eric@anholt.net; devicetree@vger.kernel.org; linux-kernel@vger.kernel.org; linux-arm-kernel@lists.infradead.org; linux-scsi@vger.kernel.org; zangleigang; Gengjianfeng; guodong.xu@linaro.org; zhangfei.gao@linaro.org; Fengbaopeng (kevin, Kirin Solution Dept) 主题: Re: [PATCH v6 2/5] dt-bindings: scsi: ufs: add document for hisi-ufs On Thu, Dec 07, 2017 at 06:20:23PM +0800, Li Wei wrote:
