+Method 1b: Declare the I2C devices via devicetree
+-------------------------------------------------
+
+This method has the same implications as method 1a. The declaration of I2C
+devices is here done via devicetree as subnodes of the master controller.
+
+Example:
+

+Here, two devices are attached to the bus using a speed of 100kHz. For

+to its devicetree documentation in Documentation/devicetree/bindings/.

+ Linux 在 AArch64 中带标记的虚拟地址
+ =================================
+
+作者: Will Deacon <will.deacon@arm.com>
+日期: 2013 年 06 月 12 日
+
+本文档简述了在 AArch64 地址转换系统中提供的带标记的虚拟地址及其在
+AArch64 Linux 中的潜在用途。
+
+内核提供的地址转换表配置使通过 TTBR0 完成的虚拟地址转换（即用户空间
+映射），其虚拟地址的最高 8 位（63:56）会被转换硬件所忽略。这种机制
+让这些位可供应用程序自由使用，其注意事项如下：
+
+ (1) 内核要求所有传递到 EL1 的用户空间地址带有 0x00 标记。
+ 这意味着任何携带用户空间虚拟地址的系统调用（syscall）
+ 参数 *必须* 在陷入内核前使它们的最高字节被清零。
+
+ (2) 非零标记在传递信号时不被保存。这意味着在应用程序中利用了
+ 标记的信号处理函数无法依赖 siginfo_t 的用户空间虚拟
+ 地址所携带的包含其内部域信息的标记。此规则的一个例外是
+ 当信号是在调试观察点的异常处理程序中产生的，此时标记的
+ 信息将被保存。
+
+ (3) 当使用带标记的指针时需特别留心，因为仅对两个虚拟地址
