<p class=MsoPlainText>Hi,<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I'm a newbie for linux device driver development.<o:p></o:p></p>
<p class=MsoPlainText>We have a custom ppc405 board which has MCP23S17<o:p></o:p></p>
<p class=MsoPlainText>(16-Bit I/O Expander with SPI Interface) on it.<o:p></o:p></p>
<p class=MsoPlainText>I noticed that current kernel has MCP23S08 driver<o:p></o:p></p>
<p class=MsoPlainText>support, I'd like to know:<o:p></o:p></p>
<p class=MsoPlainText>1. if passing platform data to MCP23S08 driver, can it
make<o:p></o:p></p>
<p class=MsoPlainText> MCP23S17 work?<o:p></o:p></p>
<p class=MsoPlainText>2. Generally, I'd like to know how to pass platform data
to<o:p></o:p></p>
<p class=MsoPlainText> a particular device driver. In my mind,
platform data should<o:p></o:p></p>
<p class=MsoPlainText> not be in driver code, right? However, I
don't know where is<o:p></o:p></p>
<p class=MsoPlainText> the suitable place to pass platform data to
driver.<o:p></o:p></p>
<p class=MsoPlainText>3. How to describe this in dts file?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Thanks in advance,<o:p></o:p></p>
<p class=MsoNormal>YiFei<o:p></o:p></p>
