Subject: question: Multiple mcp23s08 on one chip-select with OF
Date: Thu, 12 Jun 2014 10:12:52 +0200 [thread overview]
Message-ID: <53996104.9070103@mycable.de> (raw)
Introduction:
Multiple mcp23s08 can be accessed individually with the same
chip-select when they have different addresses configured.
They are configured as one spi-slave and there is one spi-chip created
for each mcp23s08.
My Question:
How can I reference a single mcp23s08 gpio-chip in my device-tree. When
I use the of-handle of the spi-slave, I only reference the first mcp23s08.
Best Regards
Michael
