anarsoul: jack detection is tied to the HBIAS line. It senses current draw changes, like when you plug in a headset, mic ring is either tied to ground if the headset doesn't have a mic
02:42
<

or the mic would draw phantom power
02:43
<
wens >
also buttons on phone headsets would effect a resistor network on the mic line
02:43
<
anarsoul >
wens: that's fine, but yet code should be written for sun8i-codec and sun50i-codec-analog
02:43
<
anarsoul >
and I'm not sure how to tie them up
02:44

how would you do this there?

absolutely not

there are many resolutions which can't work with that base frequency

I thought that hdmi phy clk is fixed

in this case you will get only 16 possible pixel clocks

no, it has to be the same as pixel clock

do you guys use any free-cloud-thingy to build the kernels ?

if PLL_MIPI is cruical for MIPI working, then yes
17:43

jaganteki: but HDMI PHY has clock parents specified in DT for different reason
17:44

jernej >
clock gets created by HDMI PHY driver
17:44
<
jernej >
whereas in MIPI case, all clocks are already created by clock driver
17:46
<
jaganteki >
but PLL's must need by respective clk parents, what do you mean "if PLL_MIPI is actually needed for MIPI "
17:46
<
jaganteki >
is there any case PLL_MIPI doesn't for MIPI bus or anyothers
17:47
<
jernej >
just because PLL is named PLL_MIPI that doesn't mean it is strictly necessary for MIPI, just convinient

unless you prove that by HW tests

i see a number of BOARD-u-boot.dtsi includes for things out of sync with upstream
18:38
<

maybe that's for more specific issues

anarsoul|2: progress! i've got it partially working with slightly patched upstream pinebook.dts
22:32
<
vagrantc >
anarsoul|2: working, as in, once linux boots, the display works
22:33
<
vagrantc >
anarsoul|2: in u-boot the LCD flashes briefly and then goes dark until linux boots up
22:33
<
anarsoul|2 >
vagrantc: I guess you're missing fixed regulator in config
22:33
<
anarsoul|2 >
anyway, boot with serial connected and check what's going on
22:34
<
vagrantc >
i see output on the serial, but nothing obvious as to what's wrong
22:34
<
vagrantc >
i can even see the u-boot output on the LCD briefly
22:34
<
anarsoul|2 >
then it's probably backlight
22:36
<
anarsoul|2 >
check that you have CONFIG_DM_REGULATOR_FIXED=y in config
22:41
<
vagrantc >
yeah, have that
22:42
<
anarsoul|2 >
check 'dm tree' output
22:42
<
anarsoul|2 >
paste it somewhere and provide a link
22:46
<
vagrantc >
got it after adding the vdd_bl stuff from your original patches
22:49
<
anarsoul|2 >
backlight is here
22:49
<
anarsoul|2 >
that's weird
22:52
<
vagrantc >
is DM_I2C_GPIO needed for the panel/backlight/etc ?

yeah, that should also work
23:19
<
anarsoul|2 >
vagrantc: well, according to 'dm tree' backlight is on
23:20
<
anarsoul|2 >
if screen is black try to light it up with flashlight (use your phone :)) in dark room
23:20
<
anarsoul|2 >
if you see the text then backlight isn't working
23:20
<
anarsoul|2 >
for some reason
23:22
<
vagrantc >
yup, shining a light on certain angles shows the screen
23:23
<
vagrantc >
probably my botched attempt at merging upstream
23:23
<
vagrantc >
upstream .dts
23:23
<
anarsoul|2 >
vagrantc: I'll rebase my patches on u-boot master and see if it boots tonight
23:23
<
vagrantc >
anarsoul|2: you want a copy of my latest?
23:23
<
anarsoul|2 >
nah, I'm good, thanks :)
23:24
<
anarsoul|2 >
well, if you addressed comments for eMMC calibration I'd take it
23:24
<
vagrantc >
i took the lazy way on that
23:24
<
vagrantc >
just ifdef based on MACH_SUN50...
23:24
<

that's the patch that causes most of the pain
23:25
