Bring up the SM6125 DPU now that all preliminary series (such as INTF
TE) have been merged (for me to test the hardware properly), and most
other conflicting work (barring ongoing catalog *improvements*) has made
its way in as well or is still being discussed.
The second part of the series complements that by immediately utilizing
this hardware in DT, and even enabling the MDSS/DSI nodes complete with
a 6.0" 1080x2520 panel for Sony's Seine PDX201 (Xperia 10 II).
The last patch ("sm6125-seine: Configure MDSS, DSI and panel") depends
on (an impending v2 of) my Sony panel collection series [1].

Changes in v3:
- Drop status="disabled" from MDSS dt-bindings example;
- Use "nom" instead of "svs" OPP for dsi-phy PD, matching downstream;
- Add "retention" OPP to dispcc PD;
- Reword dsi-phy required-opps documentation;
- Rebased on latest -next and fixed conflicts in DT and DPU catalog;
- Link to v2: https://lore.kernel.org/r/20230627-sm6125-dpu-v2-0-03e430a2078c@xxxxxxxxxxxxxx
Changes in v2:
- Moved dispcc DT clock reordering to the right patch (--fixup on the
wrong hash) (Dmitry, Konrad multiple times);
- Drop removal of GCC_DISP_AHB_CLK in dispcc bindings. While it is
unused in the current driver, it is likely used to ensure a guaranteed
probe order between GCC and DISPCC downstream, as well as currently
relying on the fact that GCC_DISP_AHB_CLK is CLK_IS_CRITICAL and never
turned off (Bjorn);
- Add GCC_DISP_GPLL0_DIV_CLK_SRC at the end of the dispcc clock list to
maintain some form of ABI stability (Krzysztof);
- Use SoC-prefix format for 14nm DSI PHY qcom,sm6125-dsi-phy-14nm
compatible (Dmitry, Krzysztof);
- Add patch to drop unused regulators from QCM2290 14nm DSI PHY (Konrad,
Dmitry);
- Reuse QCM2290 14nm DSI PHY config struct for SM6125 compatible
(Konrad);
- s/sde/mdss in pdx201.dts pinctrl node names and labels (Konrad);
- Use MX power domain in DSI PHY with SVS OPP (Dmitry);
- Use CX power domain with (already-existing) OPP table in DSI CTRL
(Konrad, Dmitry);
- Rebased on top of DPU catalog rework [1] by inlining macro
invocations, and validated by diffing stripped dpu_hw_catalog.o that
there are no unexpected changes;
- Unset min_llcc_ib because this platform has no LLCC (Konrad);
- Fix UBWC comment to mention "encoding" version (Dmitry);
- Reordered DT nodes to follow Konrad's requested sorting;
- Add power-domains and required-opps properties to dsi-phy-14nm.yaml;
- Link to v1: https://lore.kernel.org/r/20230624-sm6125-dpu-v1-0-1d5a638cebf2@xxxxxxxxxxxxxx
The discussions and this list ran quite long, apologies if I missed or
mis-resolved anything in advance!
