00:01 <tokyovigilante> wens: sorry to bring up an old comment but are you able to elaborate on this comment about the sun4i codec jack-detection? "in that case the headphone switch should be an aux device to the existing sound card. the sun4i-codec driver can't do simple-card because it is already completely self contained"

00:02 <tokyovigilante> https://oftc.irclog.whitequark.org/linux-sunxi/2024-10-21#33676911

00:03 <tokyovigilante> Do you mean I would need to add relevant implementation as described by https://docs.kernel.org/sound/soc/jack.html?

01:51 <Jookia> triskit: im interested in documenting and setting up secure boot

01:54 <triskit> Jookia: me too, but progress is slow on my side. I’m designing carrier board for the Lichee RV and hope to eventually be able to secure boot it

01:55 <Jookia> that's the D1 isn't it?

01:55 <triskit> Yeah

01:55 <Jookia> if you need guaranteed security i wouldn't use allwinner

01:56 <Jookia> for my use case i figure it's better than nothing and i want to document it anyway

01:56 <Jookia> but if you're actually handling sensitive data or something please don't use allwinner for security

01:57 <triskit> Yup, luckily I don’t need real security

02:01 <Jookia> im a bit pessimistic about the modern attitude towards security :)

02:04 <jakllsch> i'm a bit pessimistic about, well, everything

02:04 <jakllsch> :-P

02:05 <Jookia> haha

09:37 <loki666> there is something I don't understand in the dts, it would seems we can define regulators nodes and use them as supply for whatever device node needs them (gpu, mmc, usb) but I don't understand how a driver can understand that to config the pmic? could someone explain me, or just I'm complelty wrong about this because dts just describe what's

09:37 <loki666> basically wired on the PCB, and a driver can't change that

09:38 <Jookia> loki666: a driver can ask to enable or disable a regulator, the pmic node provides regulators and i think you configure voltages there

09:38 <loki666> but then some regulators do have a microvolt range so something should be able to change that (opp)

09:38 <Jookia> i think drivers can request specific voltages for regulators

09:38 <Jookia> but most i personally have used don't

09:38 <Jookia> since the hardware tends to require fixed voltage rails

09:39 <loki666> yes yes, but what I don't understand is how the pmic driver is able to understand which rails to change for the regulatore I named "gpu-vdd"

09:39 <Jookia> can you show me your dt?

09:40 <loki666> le me try to findsome in mainline

09:41 <loki666> https://github.com/torvalds/linux/blob/4a5df37964673effcd9f84041f7423206a5ae5f2/arch/arm64/boot/dts/allwinner/sun50i-h700-anbernic-rg35xx-2024.dts#L189C18-L189C27

09:42 <Jookia> loki666: that's defined on line 303 by nodename cldo3

09:42 <Jookia> i believe the driver matches cldo3

09:42 <loki666> so the pmic driver expect to find a subnode cldo3

09:43 <Jookia> yeah

09:43 <Jookia> i believe

09:43 <Jookia> i didn't check but it should

09:51 <loki666> mmmh ok, thanks
