1. Do anyone find S5P4413 spi driver code in Debian kernel source tree ?
I try common SPI test code (spidev_test.c) but read all zero back.
https://github.com/KnCMiner/spi-test/bl ... spi-test.c
It seems there is no proper SPI driver include in linux driver.
2. How to enable second SPI ?
From the S5P4418's spec. there are 3 SPI controllers
How to enable the second one in kernel ?
Best Regards,
