drm/msm/dsi: Fix DSI index detection when version clash occurs 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.

drm/msm/dsi: Take advantage of devm_regulator_bulk_get_const() As of the commit 1de452a0edda ("regulator: core: Allow drivers to define their init data as const") we no longer need to do copying of regulator bulk data from initdata to something dynamic. Let's take advantage of that. In addition to saving some code, this also moves us to using ARRAY_SIZE() to specify how many regulators we have which is less error prone. This gets rid of some layers of wrappers which makes it obvious that we can get rid of an extra error print. devm_regulator_bulk_get_const() prints errors for you so you don't need an extra layer of printing. In all cases here I have preserved the old settings without any investigation about whether the loads being set are sensible. In the cases of some of the PHYs if several PHYs in the same file used exactly the same settings I had them point to the same data structure. NOTE: Though I haven't done the math, this is likely an overall savings in terms of "static const" data. We previously always allocated space for 8 supplies. Each of these supplies took up 36 bytes of data (32 for name, 4 for an int).

drm/msm/dsi: Don't get DSI index from DT The DSI host and PHY driver currently expects the DT bindings to provide custom properties "qcom,dsi-host-index" and "qcom,dsi-phy-index" so that the driver can identify which DSI instance it is. The binding isn't acceptable, but the driver still needs to figure out what its instance id. This is now done by storing the mmio starting addresses for each DSI instance in every SoC version in the driver. The driver then identifies the index number by trying to match the stored address with comparing the resource start address we get from DT. We don't have compatible strings for DSI PHY on each SoC, but only the DSI PHY type. We only support one SoC version for each PHY type, so we get away doing the same thing above for the PHY driver. We can revisit this when we support two SoCs with the same DSI PHY. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
