6 years ago Hello slic device le88221 is connected to the spi bus. But actual spi driver in linux kernel is inefficient because it doesn't allow toggling CS signal between each byte. So transfer are very slow That's why i integrate spi module in bcm63xx-phone kernel module and modified the code to allow very fast transfer. But of course it conflicts with linux kernel spi module That's why you have to disable the spi module in the linux kernel and recompile it. Either you apply the patch 000-disable-spi-bcm63xx-module.patch in bcm63xx-phone/patches/17.01. Or you run make kernel_menuconfig and disable the spi driver.
Hello, I am trying now to compile your driver with Lede 17.01.4. I cannot understand the modiffy I need to do for spi. With no modify, when I start module I have

Cna you please explain which patch I need when I compile Lede?
