Date: Fri, 31 Aug 2018 14:34:02 +0200 From: Philipp Zabel <p.zabel@...gutronix.de> To: Lee Jones <lee.jones@...aro.org> Cc: linux-kernel@...r.kernel.org, kernel@...gutronix.de, Marek Vasut <marek.vasut+renesas@...il.com>, Mark Brown <broonie@...nel.org>, Geert Uytterhoeven <geert+renesas@...der.be> Subject: [PATCH] regulator: da9063: fix DT probing with constraints Commit 1c892e38ce59 ("regulator: da9063: Handle less LDOs on DA9063L") reordered the da9063_regulator_info[] array, but not the DA9063_ID_* regulator ids and not the da9063_matches[] array, because ids are used as indices in the array initializer. This mismatch between regulator id and da9063_regulator_info[] array index causes the driver probe to fail because constraints from DT are not applied to the correct regulator: da9063 0-0058: Device detected (chip-ID: 0x61, var-ID: 0x50) DA9063_BMEM: Bringing 900000uV into 3300000-3300000uV DA9063_LDO9: Bringing 3300000uV into 2500000-2500000uV DA9063_LDO1: Bringing 900000uV into 3300000-3300000uV DA9063_LDO1: failed to apply 3300000-3300000uV constraint(-22) This patch reorders the DA9063_ID_* as apparently intended, and with them the entries in the da90630_matches[] array.
