[PATCH v2 0/9] Fix DSI host idx detection on HW revision clash

[PATCH v2 0/9] Fix DSI host idx detection on HW revision clash

[Konrad Dybcio]

v1 -> v2:
- squash the 2d-array-ification and fixing up the logic into one patch
- drop num_variants, loop over VARIANTS_MAX*DSI_MAX unconditionally
- drop inadequate Fixes: tags
- pick up rbs

v1: https://lore.kernel.org/linux-arm-msm/20230211115110.1462920-1-konrad.dybcio@linaro.org/


Some DSI host versions are implemented on multiple SoCs which use
vastly different register maps. This messes with our current
assumptions of being able to map {dsi0, dsi1} to {reg0, reg1}.
Solve that by adding a way of specifying multiple sets of base
registers and try comparing them against the register specified in DT
until we find a match.

This removes the need for the QCM2290-specific compatible which was
used in the SM6115 DT (which uses DSIv2.4.1, just like SC7180).
The series also takes care of that.

Tested on SM6115P Lenovo Tab P11 and SM8350 PDX215

[PATCH v2 2/9] drm/msm/dsi: Get rid of msm_dsi_config::num_dsi

In preparation for supporting multiple sets of possible base registers,
remove the num_dsi variable. We're comparing the io_start array contents
with the reg value from the DTS, so it will either match one of the
expected values or don't match against a zero (which we get from partial
array initialization).

[PATCH v2 3/9] drm/msm/dsi: Fix DSI index detection when version clash occurs

[Konrad Dybcio]

Currently, we allow for MAX_DSI entries in io_start to facilitate for
MAX_DSI number of DSI hosts at different addresses. The configuration
is matched against the DSI CTRL hardware revision read back from the
component. We need a way to resolve situations where multiple SoCs
with different register maps may use the same version of DSI CTRL. In
preparation to do so, make msm_dsi_config a 2d array where each entry
represents a set of configurations adequate for a given SoC.

This is totally fine to do, as the only differentiating factors
between same-version-different-SoCs configurations are the number of
DSI hosts (1 or 2, at least as of today) and the set of base registers.
The regulator setup is the same, because the DSI hardware is the same,
regardless of the SoC it was implemented in.

In addition to that, update the matching logic such that it will loop
over VARIANTS_MAX variants, making sure they are all taken into account.

[PATCH v2 3/9] drm/msm/dsi: Fix DSI index detection when version clash occurs

[Konrad Dybcio]

Currently, we allow for MAX_DSI entries in io_start to facilitate for
MAX_DSI number of DSI hosts at different addresses. The configuration
is matched against the DSI CTRL hardware revision read back from the
component. We need a way to resolve situations where multiple SoCs
with different register maps may use the same version of DSI CTRL. In
preparation to do so, make msm_dsi_config a 2d array where each entry
represents a set of configurations adequate for a given SoC.

This is totally fine to do, as the only differentiating factors
between same-version-different-SoCs configurations are the number of
DSI hosts (1 or 2, at least as of today) and the set of base registers.
The regulator setup is the same, because the DSI hardware is the same,
regardless of the SoC it was implemented in.

In addition to that, update the matching logic such that it will loop
over VARIANTS_MAX variants, making sure they are all taken into account.

[PATCH v2 5/9] drm/msm/dsi: dsi_cfg: Merge SC7180 config into SDM845

[Konrad Dybcio]

The configs are identical, other than the number of *maximum* DSI
hosts allowed. This isn't an issue, unless somebody deliberately
tries to access the inexistent host by adding a dt node for it.

Remove the SC7180 struct and point the hw revision match to the
SDM845's one. On a note, this could have been done back when
7180 support was introduced.

[PATCH v2 6/9] drm/msm/dsi: Switch the QCM2290-specific compatible to index autodetection

[Konrad Dybcio]

Now that the logic can handle multiple sets of registers, move
the QCM2290 to the common logic and mark it deprecated. This allows us
to remove a couple of structs, saving some memory.

[PATCH v2 6/9] drm/msm/dsi: Switch the QCM2290-specific compatible to index autodetection

[Konrad Dybcio]

Now that the logic can handle multiple sets of registers, move
the QCM2290 to the common logic and mark it deprecated. This allows us
to remove a couple of structs, saving some memory.

This looks incomplete. You also need to add it to MDSS binding.
