[replying to v1 to keep the same series on Patchwork]
That is not the right way to do it.
If you reply to an old series, the tooling does not pickup the new version
as a separate series.

Hi,
I noticed that it indeed didn't work. However, Patchwork didn't pick up the v2
cover letter at all, so I thought replying to v2 would mess up the thread even
more.
That being said, the v3 cover letter is not visible there either.
Should I resend this as v4 [which message to reply to?] or send a completely
new series perhaps?
I apologize for the confusion, this is my first time doing that.
Regards
Kuba
Some Allwinner chips (notably the D1s/T113 and the A100) have a "combo
MIPI DSI D-PHY" which is required when using single-link LVDS0. The same
PD0..PD9 pins are used for either DSI or LVDS.
Other than having to use the combo D-PHY, LVDS output is configured in
the same way as on older chips.
This series enables the sun6i MIPI D-PHY to also work in LVDS mode. It
is then configured by the LCD TCON, which allows connecting a
single-link LVDS display panel.
Changes in v2/v3:
- Applied code formatting changes from review comments
- Changed "dphy" to "combo-phy"
- Made the LVDS setup/teardown functions abort early in case of error
(adding a proper return value would require changes in several levels
of caller functions; perhaps could be done in a separate patch)
- Added the PHY properties to DT bindings
- Renamed lvds0_pins to lcd_lvds0_pins
- Rebased on top of drm/misc/kernel/for-linux-next
- Hopefully corrected the incomplete patch list of v2, which happened
due to an SMTP error
