As we know now, value 0x50 meaning is:
- HW mode
- regular output type
- low level at output
0x00 meaning is:
- SW mode
- open-drain output
- low level at output
I don't know what exactly "HW/SW mode" means but I suppose that this pin
can be controlled by PMIC internal charge state algorithm (if it is
enabled) or by software (extcon driver).
So, if we set 0x50 value and disable HW-controlled charging entirely (as
extcon driver does), we don't set 'charger enable' signal to low as
expected. Its exactly state is unknown, but I checked – it is HIGH.
Charger doesn't start charging with this value and starts with 0x00.
0x0b register of 0x6b device on bus 7 – it is the status register of BQ25892
charger, where bits 3,4 describe charging state, 10b means fast charging,
00b means not charging.

0x06
After reading of Intel's and Lenovo's sources i understood that Intel's
meaning of CHGDISFN_EN_CCSM_VAL is 'enable HW control of charging' and
Lenovo's is 'enable charging'. Lenovo set this value immediately after
probing and after resume, Intel – only after resume. HW-controlled
charging is disabled entirely at probing, so I don't know how Intel's
driver enables charging.
So, I propose:
1) save initial value of CHGDIS register for restoring it at driver
remove (because the extcon-intel-cht-wc driver restores HW control in
cht_wc_extcon_remove()).
2) at driver start, enable SW control of CHGDIS and set its value to 0.
3) at driver removing, restore the saved state.
Q: In theory, enabling of 'charge enable' output without of properly
configuration of external charger can cause some problems (USB overload,
battery overcurrent etc.). I think that there are no such stupidly
designed devices exist but we cannot be sure. What should we do with this?
