+additional properties which might be needed to set up the device, please refer
+to its devicetree documentation in Documentation/devicetree/bindings/.

+
+Method 1c: Declare the I2C devices via ACPI
+-------------------------------------------
+
+ACPI can also describe I2C devices. There is special documentation for this
+which is currently located at Documentation/acpi/enumeration.txt.
+
+
 Method 2: Instantiate the devices explicitly

+                Linux 在 AArch64 中带标记的虚拟地�
+                =================================
+
+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�转�系统中�供的带标记的虚拟地��其在
+AArch64 Linux 中的潜在用途。
+
+内核�供的地�转�表�置使通过 TTBR0 完�的虚拟地�转�（�用户空间
+映射），其虚拟地�的最高 8 �（63:56）会被转�硬件所忽略。这�机制
+让这些��供应用程�自由使用，其注�事项如下：
+
+        (1) 内核�求所有传递到 EL1 的用户空间地�带有 0x00 标记。
+            这�味�任何�带用户空间虚拟地�的系统调用（syscall）
+            �数 *必须* 在陷入内核�使它们的最高字节被清零。
+
+        (2) �零标记在传递信�时�被�存。这�味�在应用程�中利用了
+            标记的信�处�函数无法�赖 siginfo_t 的用户空间虚拟
+            地�所�带的包�其内部域信�的标记。此规则的一个例外是
+            当信�是在调试观察点的异常处�程�中产生的，此时标记的
+            信�将被�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�
+            的高字节，C 编译器很�能无法判断它们是��的。
+
+此构架会阻止对带标记的 PC 指针的利用，因此在异常返回时，其高字节
+将被设置�一个为 “55� 的扩展符。
