18:47 <macromorgan> dumb question, but does anyone with driver experience know why writel and readl work during driver probe but not when I actually try to use the device? Getting things like Asynchronous SError Interrupt and whatnot.

19:07 <ndufresne> macromorgan: perhaps the chip powered off by power management, or clock gated

19:08 <ndufresne> (the last one would just deadlock iirc)

19:13 <macromorgan> okay, I disabled all power management so hopefully that isn't it

19:13 <macromorgan> I'll confirm the clocks are working I guess

21:39 <Kadigan> Hey, I'm trying to build something for the NanoPI R2S, and I was wondering -- is the serial part of the chip? If so, who came up with the damn 1.5M baud rate?! :D

22:07 <macromorgan> Kadigan: it's probably 1.5M because that's how it's set up in the Rockchip Mini Loader. You can change that in the devicetree for U-boot or Linux and get it to a different speed, assuming you're planning to roll your own kernel or U-boot.

22:10 <mps> kobol helios64 board also have this speed

22:10 <mps> iirc

22:12 <mps> or it was 150000, I forgot exact number

22:17 <anarsoul> Kadigan: IIRC UART has 24mhz base clock and integer divider, so you can't get 115200 out of it

22:22 <Kadigan> macromorgan: someone's helping me out with a Yocto-based approach, so I guess I have that option -- I just need to learn some more to figure out what to change, and how to do it appropriately.

22:23 <Kadigan> I just happen to have two UART ifaces, both on SIL2102, and that goes up to 1M maximum. :/

22:23 <Kadigan> (at least in the solutions I have)

22:23 <Kadigan> Ah, well. Thanks.
