Using\na platform_device_id table instead of DT compatible matching avoids the\nneed for a separate compatible property in the \"regulators\" node, which\nsimplifies the DT bindings and makes the parent MFD device responsible\nfor selecting the correct regulator driver for the PMIC.\n\nHowever, this means that the regulator device is not automatically\nassociated with the \"regulators\" node. Tell the regulator core to\nperform device tree lookups using the parent MFD device instead of\nthe regulator sub-device and set the .regulators_node member in all\nregulator definitions so that the \"regulators\" sub-node is used.\n\nAcked-by: Mark Brown \nSigned-off-by: Otto Pflüger \n---\n drivers/regulator/sc2731-regulator.c | 10 +++++++++-\n 1 file changed, 9 insertions(+), 1 deletion(-)","diff":"diff --git a/drivers/regulator/sc2731-regulator.c b/drivers/regulator/sc2731-regulator.c\nindex 5447e1a47d15..93c8156c5110 100644\n--- a/drivers/regulator/sc2731-regulator.c\n+++ b/drivers/regulator/sc2731-regulator.c\n@@ -131,6 +131,7 @@ static const struct regulator_ops sc2731_regu_linear_ops = {\n \t\t\t vstep, vmin, vmax) {\t\t\t\\\n \t.name\t\t\t= #_id,\t\t\t\t\\\n \t.of_match\t\t= of_match_ptr(#_id),\t\t\\\n+\t.regulators_node\t= of_match_ptr(\"regulators\"),\t\\\n \t.ops\t\t\t= &sc2731_regu_linear_ops,\t\\\n \t.type\t\t\t= REGULATOR_VOLTAGE,\t\t\\\n \t.id\t\t\t= SC2731_##_id,\t\t\t\\\n@@ -226,7 +227,7 @@ static int sc2731_regulator_probe(struct platform_device *pdev)\n \t\treturn ret;\n \t}\n \n-\tconfig.dev = &pdev->dev;\n+\tconfig.dev = pdev->dev.parent;\n \tconfig.regmap = regmap;\n \n \tfor (i = 0; i < ARRAY_SIZE(regulators); i++) {\n@@ -242,12 +243,19 @@ static int sc2731_regulator_probe(struct platform_device *pdev)\n \treturn 0;\n }\n \n+static const struct platform_device_id sc2731_regulator_id_table[] = {\n+\t{ \"sc2731-regulator\" },\n+\t{ }\n+};\n+MODULE_DEVICE_TABLE(platform, sc2731_regulator_id_table);\n+\n static struct platform_driver sc2731_regulator_driver = {\n \t.driver = {\n \t\t.name = \"sc27xx-regulator\",\n \t\t.probe_type = PROBE_PREFER_ASYNCHRONOUS,\n \t},\n \t.probe = sc2731_regulator_probe,\n+\t.id_table = sc2731_regulator_id_table,\n };\n \n module_platform_driver(sc2731_regulator_driver);\n","prefixes":["v2","5/5"]}
