[I] <d​simic> good point

PINE64 dev

22 Jan 2025 12:15

[I] <d​simic> awesome :)

[I] <D​aanct12> megi: the display jags still shows up

[M] <a​narsoul> Are there any known issues with HDMI DDC on Rock64?

PINE64 dev

09 Jan 2025 15:24

[I] <T​ofe> oh, that's quite some time ago :)

PINE64 dev

09 Jan 2025 15:23

[I] <T​ofe> yes, I get some data via uart (after some obscure initialization sequence on the i2c bus), but it's not matching what the userland driver expects

[I] <m​egi> I only had issues with the need for calibration of the touchscreen

PINE64 dev

09 Jan 2025 15:21

[I] <m​egi> the controller in touchlux3 is a bit different from the one you named

[I] <m​egi> Herrie1982: my touchlux 3 pocketbook uses cypress touchscreen

PINE64 dev

09 Jan 2025 15:07

Was wondering if you maybe have some ideas/thoughts on what might be wrong

PINE64 dev

09 Jan 2025 15:06

@megi I noticed you recently toyed with some Cypress kernel driver

PINE64 dev

09 Jan 2025 14:53

[I] <m​egi> but the output clock would be slower in u-boot

[I] <m​egi> dclk1_vop_div

PINE64 dev

09 Jan 2025 14:48

[I] <m​egi> are you sure all clocks are set up correctly on rk3566 for vop2/mipi-dsi out?

PINE64 dev

22 Jan 2025 14:17

[I] <m​egi> it's not the only parameter to be interested in... old driver is fairly good at power saving. it would be interesting to see how the new one compares.

[M] <p​iggz> anarsoul: dsimic: have rolled out kernel 6.13 to PP (and pPP) with the new wlan driver. Seems ok to me, i had 45mbps on fast.com

PINE64 dev

11 Jan 2025 03:38

[M] <a​narsoul> nevermind, bad HDMI cable

PINE64 dev

09 Jan 2025 15:24

[I] <m​egi> touchlux3 support was something I was doing before pinephone

PINE64 dev

09 Jan 2025 15:24

[I] <m​egi> dunno I worked on this like 6 years ago :)

PINE64 dev

09 Jan 2025 15:22

Just not sure how we could debug what's wrong really at this point. Tofe get's some data but it seems to be in the "wrong format"

PINE64 dev

09 Jan 2025 15:21

megi: Some background: we're trying to mainline HP TouchPad (tenderloin) msm8660 which uses this exotic (and non documented touchscreen). We have downstream drivers, schematics of the tenderloin board and there is a more or less working similar board. So it could be something small in dts

PINE64 dev

09 Jan 2025 15:13

[I] <m​egi> someone removed the driver from the mainline kernel, so I just reintorduced it and re-applied my patches on top to make it compatible with DT

PINE64 dev

09 Jan 2025 15:10

[I] <T​ofe> To be precise it's a cy8ctma395, and the generic gen3 kernel driver in 6.10 doesn't work for that chip it seems

PINE64 dev

09 Jan 2025 15:07

We have some obscure Gen3 that had both uart and i2c and having some issues

PINE64 dev

09 Jan 2025 15:04

[I] <D​aanct12> hmm

PINE64 dev

09 Jan 2025 14:52

[I] <m​egi> given that it's a divider and has quite a low value to begin with, it may have quite a large effect

PINE64 dev

09 Jan 2025 14:49

[I] <D​aanct12> it shows 0x406 in linux, but 0x408 in u-boot

PINE64 dev

09 Jan 2025 14:49

[I] <D​aanct12> i noticed this value is a bit off

PINE64 dev

09 Jan 2025 14:48

[I] <m​egi> maybe the clock is too fast or slow? on PPP I configure some clocks needed for display in clk driver to a fixed values https://xff.cz/git/u-boot/commit/?h=megi-v2024.10&amp;id=40677dba7103e214c45373fbc9961cffd650e28a
