several ways to achieve this, depending on the context and requirements.

Method 1: Declare the I2C devices by bus number
|

-----------------------------------------------
|
||||
Method 1a: Declare the I2C devices by bus number
|
||||
------------------------------------------------
|
||||
|
||||
This method is appropriate when the I2C bus is a system bus as is the case
|
||||
for many embedded systems. On such systems, each I2C bus has a number
|
||||
|
|
@ -51,6 +51,43 @@ The devices will be automatically unbound and destroyed when the I2C bus
|
|||
they sit on goes away (if ever.)
|
||||
|
||||
|
||||
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:
|
||||
|
||||
i2c1: i2c@400a0000 {
|
||||
/* ... master properties skipped ... */
|
||||
clock-frequency = <100000>;
|
||||
|
||||
flash@50 {
|
||||
compatible = "atmel,24c256";
|
||||
reg = <0x50>;
|
||||
};
|
||||
|
||||
pca9532: gpio@60 {
|
||||
compatible = "nxp,pca9532";
|
||||
gpio-controller;
|
||||
#gpio-cells = <2>;
|
||||
reg = <0x60>;
|
||||
};
|
||||
};
|
||||
|
||||
Here, two devices are attached to the bus using a speed of 100kHz. For
|
||||
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.
|
||||

phy_get and devm_phy_get can be used to get the PHY. In the case of dt boot,
|
||||
the string arguments should contain the phy name as given in the dt data and
|
||||
in the case of non-dt boot, it should contain the label of the PHY.
|
||||
The only difference between the two APIs is that devm_phy_get associates the
|
||||
device with the PHY using devres on successful PHY get. On driver detach,
|
||||
release function is invoked on the the devres data and devres data is freed.

devm_phy_get associates the device with the PHY using devres on

successful PHY get. On driver detach, release function is invoked on

the the devres data and devres data is freed. phy_optional_get and
|

devm_phy_optional_get should be used when the phy is optional. These
|
||||
two functions will never return -ENODEV, but instead returns NULL when
|
||||
the phy cannot be found.
|
||||
|

It should be noted that NULL is a valid phy reference. All phy

consumer calls on the NULL phy become NOPs. That is the release calls,
|
||||
the phy_init() and phy_exit() calls, and phy_power_on() and
|

phy_power_off() calls are all NOP when applied to a NULL phy. The NULL

phy is useful in devices for handling optional phy devices.

Linux 在 AArch64 中带标记的虚拟地址
|

=================================

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
|
||||
的高字节，C 编译器很可能无法判断它们是不同的。
|
||||
|
||||
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
|
||||
将被设置成一个为 “55” 的扩展符。
