Description Emmanuel Vadot 2015-07-29 05:07:57 UTC
Created attachment 159354 [details] rt5350 support The RT5350 is a MIPS SoC by RaLink. The SoC is pretty similar to the already in-tree RT305X. This patch adds : - Support for the RT5350F - Selection of SoC in kernel config - Add kernel config RT5350_BASE and corresponding hint files with sane defaults. - Add kernel config for the Olimex RT5350 EVB and hints files - Configuration of GPIO via pinmask/pinon and function_set/fonction_clear hint value. - Add a pinin hint value to configure a GPIO as input at boot.

hi! Cool. I'll look at committing this soon. Question: why'd you remove GPIO_BIT_SET/GPIO_BIT_CLR? You're directly calling the bus_read/bus_write code now. Is this intentional? Does this also work with RT305x?
Comment 2 Emmanuel Vadot 2015-10-24 17:01:52 UTC
The macros were removed cause they didn't work and I was too lazy at the time to check what was the problem. And, of course, after I forgot to correct and use them. I don't have any RT305x hardware to test so I don't know if I broke something or not.
Comment 3 Adrian Chadd 2015-10-24 17:05:17 UTC
ok, let's go see if I can find some RT305x and RT5350 hardware to test with.

(In reply to Emmanuel Vadot from comment #0) Thanks for working on it. I have a diff that returns the clock frequency from rt305x_clock_freq() instead of a hard coded PLATFORM_COUNTER_FREQ and supports RAM size detection. http://people.freebsd.org/~kevlo/rt5350.diff Could you test it? Thanks.

I'll try that next week. Do you have any RT305x hardware to test if my patch have any regression ? Thanks.

Mine is Hame MPR-A1. I haven't had time to test your gpio driver yet. BTW, does rt work?
Comment 7 Emmanuel Vadot 2015-10-27 07:55:16 UTC
If rt == it == gpio, yes the gpios are working. The only thing not working on the board now are the wifi chipset and the ethernet switch. I need to find some time to work on it.

Sorry, I mean the ethernet adapter (sys/dev/rt).
