Hi,
We try to porting SPI driver into new platform Gemtree (which driver working
fine on Varcolac), found it have problem to add spi device in
drivers/platform/x86/serial-multi-instantiate.c.
With re-worked CS, it report irq add failed, even applied patch
https://lore.kernel.org/all/[email protected]/
See attached DSDT code dsdt_gemtree_spi-3.txt, and DSDT table file
DSDT_gemtree-3, also dmesg log was shared as : dmesg-1203.txt.
And with first version of Gemtree, failed on add gpio for CS. See attached DSDT
code dsdt_gemtree_spi-2.txt, and log of dmesg: dmesg-1115-3.txt.
My modification in kernel is in modification-ti.txt, and our spi code was
ignored.
Also shared interrupts and status of "grep -H 15
/sys/bus/acpi/devices/*/status".
Best Regards
Jim
