| 17:34.39 | Pali | do you have some information how are connected? |
| 17:34.53 | DocScrutinizer05 | err, they are not missing? |
| 17:35.48 | DocScrutinizer05 | http://wstaw.org/m/2017/01/01/plasma-desktopa17764.png http://wstaw.org/m/2017/01/01/plasma-desktopn17764.png |
| 17:36.20 | Pali | tvout_en is 40 |
| 17:36.47 | Pali | and eci-sw2 is 182 |
| 17:37.21 | Pali | but there are no gpio 61 or gpio 178 |
| 17:37.37 | DocScrutinizer05 | sorry I don't get it |
| 17:38.01 | Pali | where is connected gpio 61? |
| 17:38.36 | Pali | I do not see it |
| 17:38.56 | DocScrutinizer05 | eci0: N4007 -> ECI0 -> OMAP:U3 GPMC_nBE1 |
| 17:40.08 | DocScrutinizer05 | eci1: N4008 -> ECI1 -> OMAP:H1 GPMC_nWP |
| 17:40.46 | DocScrutinizer05 | I don't know what's eci_sw1 |
| 17:41.29 | Pali | eci_sw1 --> #define RX51_ECI_SWITCH_1_GPIO178 |
| 17:42.21 | Pali | gpio_request(RX51_ECI_SWITCH_1_GPIO, "ECI switch 1"); gpio_direction_output(RX51_ECI_SWITCH_1_GPIO, 0); |
| 17:42.58 | DocScrutinizer05 | I don't know. In schematics I only could guess that this is ECI5 which is connected to OMAP:V3 McSPI2_CS1 and (possibly incorrectly) labeled "GPIO_182" |
| 17:43.16 | Pali | #define RX51_ECI_SWITCH_2_GPIO182 |
| 17:43.33 | Pali | gpio 182 is eci_sw2, not eci_sw1 |
| 17:43.49 | DocScrutinizer05 | I don't know what's eci_sw1 then |
| 17:43.49 | Pali | gpio_request(RX51_ECI_SWITCH_2_GPIO, "ECI switch 2"); gpio_direction_output(RX51_ECI_SWITCH_2_GPIO, 1); |
| 17:44.32 | DocScrutinizer05 | no faintest clue |
| 17:45.06 | Pali | in snd rx51.c is: static void rx51_set_eci_switches(int mode) { mode == 3: /* ECI RX/TX connected to mic/bias line */ gpio_set_value(RX51_ECI_SWITCH_1_GPIO, 1); |
| 17:45.10 | DocScrutinizer05 | haven't seen anything in schematics that might correspond to a third ECI switch apart from TV_EN and what you call eci_sw2 |
| 17:45.50 | DocScrutinizer05 | sorry I can't analyze schematics from sourcecode |
| 17:46.02 | DocScrutinizer05 | give me a pin |
| 17:46.17 | Pali | there are two gpio switches in kernel code which looks like set how is mic/bias lines connected |
| 17:46.39 | Pali | and I was not able to find that eci_sw1 in schemantics... |
| 17:47.46 | DocScrutinizer05 | there is TV_EN and an eci switch with no name |
| 17:47.55 | DocScrutinizer05 | no other but those two switches |
| 17:48.07 | Pali | tv_en is different |
| 17:48.27 | DocScrutinizer05 | in schematics it's not |
| 17:48.45 | Pali | yes, I do not see it too |
| 17:48.58 | Pali | reason why I'm asking... |
| 17:49.25 | *** join/#maemo noch (~noch@arnet.am) |
| 17:49.29 | Pali | kernel snd code is setting that gpio and I cannot understand what it is doing... |
| 17:50.17 | DocScrutinizer05 | TVOUT_EN = N4022:A1 1SEL, ECI5 = N4022:A3 2SEL |
| 17:50.40 | DocScrutinizer05 | no other swites in whole audio which might be faintly related to ECI |
| 17:51.37 | DocScrutinizer05 | ECI "bus" consists of ECI0 ECI1 and ECI5, 2,3,4 are nonexistent |
| 17:53.18 | DocScrutinizer05 | I *guess* there are fuzzy bits in kernel sourcecode comment bits and/or naming of vars |
| 17:54.43 | DocScrutinizer05 | NB there's also only eci0 and eci1 in /sys/ |
| 17:55.35 | DocScrutinizer05 | /* ECI RX/TX connected to mic/bias line */ sounds pretty bogus |
| 17:56.04 | DocScrutinizer05 | there's no such thing like "ECI RX/TX" in N900 |
| 17:56.30 | DocScrutinizer05 | RX ok maybe, but for sure no TC |
| 17:56.36 | DocScrutinizer05 | TX |
| 17:57.20 | Pali | DocScrutinizer05: run on n900: grep ECI /sys/kernel/debug/gpio |

| 17:57.26 | *** join/#maemo xes_ (~xes@unaffiliated/xes) |
| 17:57.28 | Pali | there is ECI switch 1 |
| 17:57.55 | DocScrutinizer05 | DUH!! |
| 17:58.59 | DocScrutinizer05 | so can't you find out which pin number GPIO178 is supposed to be on? |
| 17:59.45 | DocScrutinizer05 | I don't know if I can find the right table in those 3 * 3000 manual pages |
| 18:00.16 | bencoh | you're an EE ... you're supposed to :p |
| 18:00.16 | Pali | grep -i -E 'tv|eci' /sys/kernel/debug/gpio |
| 18:00.32 | DocScrutinizer05 | bencoh: too little RAM |
| 18:00.43 | Pali | this shows: tvout_sel, eci0, eci1, ecisw1, ecisw2 |
| 18:00.52 | bencoh | DocScrutinizer05: in brain or in computer? |
| 18:00.56 | bencoh | (or both?) |
| 18:00.58 | DocScrutinizer05 | latter |
| 18:01.03 | bencoh | huhu |
| 18:01.21 | Pali | tvout_sel, eci0, eci1 and ecisw2 are already identified, just that ecisw1 is unknown... |
| 18:01.34 | Pali | maybe it was just in some n900 prototype? |
| 18:01.50 | Pali | and nokia forgot to remove dead code? |
| 18:03.58 | DocScrutinizer05 | GPIO_178 aka mcspi2_clk |
| 18:05.07 | DocScrutinizer05 | aka hsusb2_data7 |
| 18:06.45 | DocScrutinizer05 | aka ball AA3 |
| 18:08.20 | DocScrutinizer05 | neither of all that shows up in schematics |
| 18:11.56 | DocScrutinizer05 | http://wstaw.org/m/2017/01/01/plasma-desktopp17764.png |
| 18:15.15 | Pali | GPIO_177 is jack insert detection (HEADPH_IND) and according to that plasma-desktopp17764.png connected to mcspi1_cs3 |
| 18:15.30 | Pali | and in rx51 schemantics HEADPH_IND is connected to mcspi1_cs3 |
| 18:15.44 | Pali | so seems that plasma-desktopp17764.png is correct for n900 |
| 18:16.05 | Pali | GPIO_178 is connected to mcspi2_clk |
| 18:16.14 | DocScrutinizer05 | yes, checked similar plausibility tests |
| 18:16.51 | DocScrutinizer05 | and I searched schematics for all mcspi and found no mcspi2_clk |
| 18:17.32 | DocScrutinizer05 | I searched for all AA3 and even W7, I searched for hsusb and found no hsusb2 |
| 18:18.47 | DocScrutinizer05 | so I dare to say the schematics have no GPIO_178 |
| 18:18.48 | Pali | maybe it is missing in rx51 schemantics? |
| 18:18.58 | DocScrutinizer05 | how could I tell? |
| 18:19.06 | Pali | or was it just for n900 prototype? |
| 18:19.16 | Pali | and later removed? |
| 18:19.19 | Pali | seems possible for me |
| 18:19.37 | DocScrutinizer05 | there *is* stuff missing in RX51 schem, at very least all about UART3 aka debug serial on testpoints |
