The opp core (drivers/opp/core.c:_generic_set_opp_regulator) does not support multiple regulators, so we'll need custom handlers. 2. Generally, platforms with 2 regulators have platform-specific constraints on how the voltages should be set (e.g. minimum/maximum voltage difference between them), so we should not just create generic handlers that simply change the voltages without taking care of those constraints. Disable devfreq for now on those GPUs.

Signed-off-by: Nicolas Boichat Reviewed-by: Tomeu Vizoso Reviewed-by: Steven Price --- (no changes since v7) Changes in v7: - Fix GPU ID in commit message Changes in v6: - Context conflicts, reflow the code. - Use ARRAY_SIZE for power domains too. Changes in v5: - Change power domain name from 2d to core2. Changes in v4: - Add power domain names. Changes in v3: - Match mt8183-mali instead of bifrost, as we require special handling for the 2 regulators and 3 power domains. drivers/gpu/drm/panfrost/panfrost_drv.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/drivers/gpu/drm/panfrost/panfrost_drv.c b/drivers/gpu/drm/panfrost/panfrost_drv.c index 83a461bdeea8..ca07098a6141 100644 --- a/drivers/gpu/drm/panfrost/panfrost_drv.c +++ b/drivers/gpu/drm/panfrost/panfrost_drv.c @@ -665,6 +665,15 @@ static const struct panfrost_compatible amlogic_data = { .vendor_quirk = panfrost_gpu_amlogic_quirk, }; +const char * const mediatek_mt8183_supplies[] = { "mali", "sram" }; +const char * const mediatek_mt8183_pm_domains[] = { "core0", "core1", "core2" }; +static const struct panfrost_compatible mediatek_mt8183_data = { + .num_supplies = ARRAY_SIZE(mediatek_mt8183_supplies), + .supply_names = mediatek_mt8183_supplies, + .num_pm_domains = ARRAY_SIZE(mediatek_mt8183_pm_domains), + .pm_domain_names = mediatek_mt8183_pm_domains, +}; + static const struct of_device_id dt_match[] = { /* Set first to probe before the generic compatibles */ { .compatible = "amlogic,meson-gxm-mali", @@ -681,6 +690,7 @@ static const struct of_device_id dt_match[] = { { .compatible = "arm,mali-t860", .data = &default_data, }, { .compatible = "arm,mali-t880", .data = &default_data, }, { .compatible = "arm,mali-bifrost", .data = &default_data, }, + { .compatible = "mediatek,mt8183-mali", .data = &mediatek_mt8183_data }, {} }; MODULE_DEVICE_TABLE(of, dt_match);
