[-- Attachment #1 --] Hi, Dne 31.01.2018 v 19:16 Shah, Nehal-bakulchandra napsal(a): > I am Nehal Shah from AMD. I am just newbie to Free BSD. Currently I have requirement to have GPIO,I2c and UART driver for AMD Platform. AMD UART and I2C drivers are based on Designware. > I can see the support of I2C driver of designware , hence I can add support for AMD Platform with ACPI IDs. > > 1. Is there any Designware ACPI based UART Driver available ? > 2. Is there ACPI GPIO based implementation available? I hope someone more informed eventually steps in, but until then, you may find following useful https://reviews.freebsd.org/rS297496 https://wiki.freebsd.org/FreeBSD/GPIO https://www.freebsd.org/doc/en/books/arch-handbook/devicedrivers.html https://nostarch.com/bsddrivers.htm Also there is some support for older AMD Geode CPU which you may find useful. Unknown to me how close is your current target platform. -- Best Regards Ondra [-- Attachment #2 --] 0 *H 010 `He 0 *H 0_0Gq0 *H 0[1 0 UCZ1,0*U #Česká pošta, s.p.
