STMicroelectronics SoC DWMAC glue layer controller
|
||||
|
||||
The device node has following properties.
|
||||
|
||||
Required properties:
|
||||
- compatible : Can be "st,stih415-dwmac", "st,stih416-dwmac" or
|
||||
"st,stid127-dwmac".
|
||||
- reg : Offset of the glue configuration register map in system
|
||||
configuration regmap pointed by st,syscon property and size.
|
||||
|
||||
- reg-names : Should be "sti-ethconf".
|
||||
|
||||
- st,syscon : Should be phandle to system configuration node which
|
||||
encompases this glue registers.
|
||||
|
||||
- st,tx-retime-src: On STi Parts for Giga bit speeds, 125Mhz clocks can be
|
||||
wired up in from different sources. One via TXCLK pin and other via CLK_125
|
||||
pin. This wiring is totally board dependent. However the retiming glue
|
||||
logic should be configured accordingly. Possible values for this property
|
||||
|
||||
"txclk" - if 125Mhz clock is wired up via txclk line.
|
||||
"clk_125" - if 125Mhz clock is wired up via clk_125 line.
|
||||
|
||||
This property is only valid for Giga bit setup( GMII, RGMII), and it is
|
||||
un-used for non-giga bit (MII and RMII) setups. Also note that internal
|
||||
clockgen can not generate stable 125Mhz clock.
|
||||
|
||||
- st,ext-phyclk: This boolean property indicates who is generating the clock
|
||||
for tx and rx. This property is only valid for RMII case where the clock can
|
||||
be generated from the MAC or PHY.
|
||||
|
||||
- clock-names: should be "sti-ethclk".
|
||||
- clocks: Should point to ethernet clockgen which can generate phyclk.

Method 1a: Declare the I2C devices by bus number

|

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:
|
||||
|
||||

additional properties which might be needed to set up the device, please refer

Method 1c: Declare the I2C devices via ACPI

ACPI can also describe I2C devices. There is special documentation for this

The 3Com Etherlink Plus (3c505) driver.
|
||||
|
||||
This driver now uses DMA. There is currently no support for PIO operation.
|
||||
The default DMA channel is 6; this is _not_ autoprobed, so you must
|
||||
make sure you configure it correctly. If loading the driver as a
|
||||
module, you can do this with "modprobe 3c505 dma=n". If the driver is
|
||||
linked statically into the kernel, you must either use an "ether="
|
||||
statement on the command line, or change the definition of ELP_DMA in 3c505.h.
|
||||
|
||||
The driver will warn you if it has to fall back on the compiled in
|
||||
default DMA channel.
|
||||
|
||||
If no base address is given at boot time, the driver will autoprobe
|
||||
ports 0x300, 0x280 and 0x310 (in that order). If no IRQ is given, the driver
|
||||
will try to probe for it.
|
||||
|
||||
The driver can be used as a loadable module.
|
||||
|
||||
Theoretically, one instance of the driver can now run multiple cards,
|
||||
in the standard way (when loading a module, say "modprobe 3c505
|
||||
io=0x300,0x340 irq=10,11 dma=6,7" or whatever). I have not tested
|
||||
this, though.
|
||||
|
||||
The driver may now support revision 2 hardware; the dependency on
|
||||
being able to read the host control register has been removed. This
|
||||
is also untested, since I don't have a suitable card.
|
||||
|
||||
Known problems:
|
||||
I still see "DMA upload timed out" messages from time to time. These
|
||||
seem to be fairly non-fatal though.
|
||||
The card is old and slow.
|
||||
|
||||
To do:
|
||||
Improve probe/setup code
|
||||
Test multicast and promiscuous operation
|
||||
|
||||
Authors:
|
||||
The driver is mainly written by Craig Southeren, email
|
||||
<craigs@ineluki.apana.org.au>.

||||

@ -75,14 +75,26 @@ Before the controller can make use of the PHY, it has to get a reference to
|
||||
it. This framework provides the following APIs to get a reference to the PHY.
|
||||
|
||||
struct phy *phy_get(struct device *dev, const char *string);
|
||||
struct phy *phy_optional_get(struct device *dev, const char *string);
|
||||
struct phy *devm_phy_get(struct device *dev, const char *string);
|
||||
struct phy *devm_phy_optional_get(struct device *dev, const char *string);
|
||||
|
||||
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.
|
||||
phy_get, phy_optional_get, devm_phy_get and devm_phy_optional_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 two
|
||||
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
|
||||
=================================
|
||||
|
||||
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
|
||||
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。
