00:59 <naobsd> srao___: is there any document I can/should see for tsadc?

01:02 <srao___> naobsd: I'm not aware of a doc, but the failure mode was simply that it wasn't updating temperature accurately -- i.e. it would get stuck

01:03 <srao___> naobsd: the HW changes we needed had to do with caps and resistors on the clkin_32k line to the rk3288 (P25)

01:07 <naobsd> it should be connected to hym8563 on firefly

01:10 levd1 has joined #linux-rockchip

01:10 <naobsd> it's enabled at power-on, can be disabled. let check driver...

01:13 levd has quit [Ping timeout: 272 seconds]

01:14 <naobsd> ah

01:14 <naobsd> hym8563_probe()->hym8563_clkout_register_clk()->i2c_smbus_write_byte_data(HYM8563_CLKOUT_DISABLE)

01:15 <naobsd> I guess there must be hym8563-clkout user in dts...

01:16 <naobsd> hmm, clock-output-names = "xin32k"; which should be used?

01:20 <naobsd> I have interest about difference between hym8563 driver and pcf8563 driver... but it's another story

01:21 <naobsd> srao___: anyway, thank you for your input! I guess it was disabled.

01:22 <naobsd> hm, name "hym8563-clkout" is used only if clock-output-names = is missed in dts

01:23 <naobsd> I think I need to add "xin32k" to tsadc node or somewhere to enable it

01:28 <srao___> I think we're carrying a patch to enable it

01:28 <srao___> https://patchwork.kernel.org/patch/5183411/

01:29 <srao___> and of course you should switch status to "enabled" in your dts

01:30 <naobsd> well, that patch is already merged

01:30 <naobsd> I think what I need is

01:31 <naobsd> &tsadc { clocks = <&hym8563>; }

01:31 <naobsd> I'll try it

01:32 <srao___> ok yeah, if your 32k clock is supplied externally, you might need that to enable this clock

01:32 <srao___> i think we have that clock coming from rk808

01:52 levd1 has quit [Ping timeout: 245 seconds]

02:06 <naobsd> oh wait, who uses 32k clk in rk3288 soc? I'm not sure clocks in tsadc node is right place...

02:07 <naobsd> (btw, on firefly, 32k clk is used by wifi/bt unit too)

02:15 <naobsd> mmind00_: I want to reorder some properties in node. "compatible" is 1st, "reg" is 2nd, then sort alphabetically, right?

02:16 <naobsd> I guess "sort alphabetically" is not strong rule, readability is prior in some case

02:19 levd has joined #linux-rockchip

02:19 <naobsd> mmm, it might not be true...

02:21 <naobsd> ok, this time I fix clock-* properties...

02:35 <naobsd> srao___: thermal zone error seems to be gone, thanks!

02:36 <naobsd> btw I cannot read /sys/class/thermal/thermal_zone?/temp by cat... cat: read error: Invalid argument

02:36 <naobsd> maybe ioctl is needed

02:40 <naobsd> strange, cat should work

02:40 <naobsd> anyway it shouldn't be a problem of dts

02:43 amstan_ is now known as amstan

03:10 <amstan> ah yes, we're down to 3, nvm, Q on quakenet is only 1

03:11 <naobsd> mmind00_: v3 sent

03:12 <naobsd> srao___: should/may I add "Suggested-By: Sonny Rao <sonnyrao@chromium.org>"?

03:55 <naobsd> mmind00_: it seems rtl8201f phy used in rayeager px2 needs: 50MHz clock input need to be configured before hard reset by gpio

03:56 <naobsd> mmind00_: currently I'm doing hard reset by pinctrl in dts, I guess it's done before configuring mac clk

03:59 <naobsd> ah

03:59 <naobsd> /* Optional regulator for PHY */

04:00 <naobsd> priv->regulator = devm_regulator_get_optional(dev, "phy");

04:00 <naobsd> I guess I can abuse this...

04:01 <naobsd> mmm, no

04:01 <naobsd> clk_set_rate(priv->refclk, 50000000); is done after regulator_enable(priv->regulator);

04:02 <naobsd> I should add reset-gpio or something into arc emac

04:05 <naobsd> I saw reset-gpio patch somewhere

13:42 <lanlaf> Is rockchip proprietary bootloader supposed to boot newer kernels like 3.10 or mainline kernel on rk3188?

13:44 <c0d3z3r0> yes, but you have to use the rk3188 dts file

13:48 <mmind00_> amstan: the gmac of rk3288 went into the network tree some days ago

13:49 <lanlaf> I have tried to boot slitaz 3.10 bootimage from here: http://talk.radxa.com/topic/88/linux-3-10-kernel-from-rockchip-for-rk3188-and-rk3288/10 but could not, I could see all the regular messages from the bootloader on the serial port, but nothing from the kernel.

13:50 <lanlaf> I am on a tronsmart mk908ii, but the image is for radxa 2013.

18:38 <viric> hi!

18:38 <viric> I'm with rkflashtool... trying to write the parameters. I write them (properly crcd)

18:39 <viric> I read them fine.. but on reboot, they are wiped

18:39 <viric> the boot says:

18:39 <viric> SdmmcInit=2 20

18:39 <viric> Fail!

18:39 <viric> unsigned!

18:39 <viric> also: Boot ver:

18:39 <viric> !!!No parameter

18:39 <viric> What am I doing wrong?

18:40 <viric> upgrade-tool tells me "prepare idb fail"

19:58 <viric> I booted in maskrom mode

19:58 <viric> but then upgrade_tool hangs on "Waiting for maskrom start"

20:01 <rperier> I pinged mturquette via email (on ML), because I cannot still find clk fixes in linux-next (I need to backport these patches all the time to work on rk3188)

20:03 <rperier> I just realized that it is for 3.19... and mturquette merged it 5 days ago... perhaps I need to wait for the next 3.19-rc ...

20:03 <rperier> so my question is stupid

20:03 <rperier> :D

20:04 <rperier> and in this case it will be automatically merged onto linux-next

20:07 <viric> meh. this maskrom mode doesn't work for me

20:07 <viric> with linux.
