[Jiaming Ouyang]

Subject: [PATCH] docs/zh_CN: add Chinese translation for usb/ohci.rst

Translate Documentation/usb/ohci.rst into Chinese Simplified.

The translation covers OHCI driver overview, hardware protocol
differences (OHCI vs UHCI), improvements since 2.4 kernel,
queueable interrupt transfers, and non-PCI support.

The git apply --check failed in my local workspace. And there are some 
translation issues below.

Also your v2 should be in the subject line, right?  Again, take a look
at the in-kernel documentation, it should explain this.

Besides the comments from Greg, I think the line above should better
belong to the Subject: line in the email headers. But there, it is a part
of email body now, i.e. the line started with 'docs/zh_CN' will appear
twice in the same commit.

Thanks.

Although this line of text is somewhat redundant, as it is the same as
the "Subject" line in the email header (git mailinfo would strip the
"Re: " by default), it is fine to leave it here.?

git.git/Documentation/git-am.adoc::[[discussion]]:

"From: ", "Date: ", and "Subject: " lines starting the body override the
respective commit author name and title values taken from the headers.

e.g. https://lore.kernel.org/git/xmqqms63ok7g.fsf@gitster.g/

But I guess you know all about this, just want to handle it here in a
simple way. ;-)

Thanks.

+它支持“开放主机控制器接口”（OHCI），该接口标准化了用于与USB 1.1主机控制器通信的
+硬件寄存器协议。“与英特尔早期的“通用主机控制器接口”（UHCI）相比，它将更多只能功能
+注入到硬件中。除英特尔和威盛之外的其他供应商的USB1.1控制器通常使用OHCI。
+
+自2.4内核以来的更改包括
+
+         - 提高了健壮性; 修复了错误; 减少了开销
+         - 支持更新和简化的usbcore API
+         - 中断传输可以更大，并且可以排队
+         - 通过使用上层“hcd”框架，减少代码量
+         - 支持一些非PCI的OHCI实现
+         - ... 以及更多
+
+“OHCI-hcd”驱动程序处理所有USB 1.1传输类型。所有类型的传输都可以排队。在“usb-ohc
+i”中也是如此，但中断传输除外。以前，使用一帧的周期会因为IRQ处理的开销而导致数据丢
+失的风险。当中断传输排队时，可以通过确保硬件在操作系统处理相关IRQ时始终有传输需要
+处理，来最大限度的降低这些风险。
