From 22161f3eb65dc29434325736c4d780908fe3bf6a Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Tue, 18 Apr 2017 11:43:49 +0100 Subject: [PATCH] regulator: arizona-micsupp: Move pdata into a separate structure In preparation for sharing this driver with Madera, move the pdata for the micsupp regulator out of struct arizona_pdata into a dedicated pdata struct for this driver. As a result the code in arizona_micsupp_of_get_pdata() can be made independent of struct arizona. This patch also updates the definition of struct arizona_pdata and the use of this pdata in mach-crag6410-module.c Signed-off-by: Richard Fitzgerald Acked-by: Lee Jones Signed-off-by: Mark Brown --- MAINTAINERS | 1 + drivers/regulator/arizona-micsupp.c | 21 +++++++++++---------- include/linux/mfd/arizona/pdata.h | 3 ++- include/linux/regulator/arizona-micsupp.h | 21 +++++++++++++++++++++ 4 files changed, 35 insertions(+), 11 deletions(-) create mode 100644 include/linux/regulator/arizona-micsupp.h diff --git a/MAINTAINERS b/MAINTAINERS index c35e0cea7831..6ed8ef18e7b6 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -13623,6 +13623,7 @@ F: include/linux/mfd/arizona/ F: include/linux/mfd/wm831x/ F: include/linux/mfd/wm8350/ F: include/linux/mfd/wm8400* +F: include/linux/regulator/arizona* F: include/linux/wm97xx.h F: include/sound/wm????.h F: sound/soc/codecs/arizona.? diff --git a/drivers/regulator/arizona-micsupp.c b/drivers/regulator/arizona-micsupp.c index 5e38861e71d8..5f8b5a713311 100644 --- a/drivers/regulator/arizona-micsupp.c +++ b/drivers/regulator/arizona-micsupp.c @@ -30,6 +30,8 @@ #include #include +#include + struct arizona_micsupp { struct regulator_dev *regulator; struct arizona *arizona; @@ -199,28 +201,26 @@ static const struct regulator_init_data arizona_micsupp_ext_default = { .num_consumer_supplies = 1, }; -static int arizona_micsupp_of_get_pdata(struct device *dev, - struct arizona *arizona, +static int arizona_micsupp_of_get_pdata(struct arizona_micsupp_pdata *pdata, struct regulator_config *config, const struct regulator_desc *desc) { - struct arizona_pdata *pdata = &arizona->pdata; struct arizona_micsupp *micsupp = config->driver_data; struct device_node *np; struct regulator_init_data *init_data; - np = of_get_child_by_name(arizona->dev->of_node, "micvdd"); + np = of_get_child_by_name(config->dev->of_node, "micvdd"); if (np) { config->of_node = np; - init_data = of_get_regulator_init_data(dev, np, desc); + init_data = of_get_regulator_init_data(config->dev, np, desc); if (init_data) { init_data->consumer_supplies = &micsupp->supply; init_data->num_consumer_supplies = 1; - pdata->micvdd = init_data; + pdata->init_data = init_data; } } @@ -232,6 +232,7 @@ static int arizona_micsupp_probe(struct platform_device *pdev) struct arizona *arizona = dev_get_drvdata(pdev->dev.parent); const struct regulator_desc *desc; struct regulator_config config = { }; + struct arizona_micsupp_pdata *pdata = &arizona->pdata.micvdd; struct arizona_micsupp *micsupp; int ret; @@ -269,15 +270,15 @@ static int arizona_micsupp_probe(struct platform_device *pdev) if (IS_ENABLED(CONFIG_OF)) { if (!dev_get_platdata(arizona->dev)) { - ret = arizona_micsupp_of_get_pdata(&pdev->dev, arizona, - &config, desc); + ret = arizona_micsupp_of_get_pdata(pdata, &config, + desc); if (ret < 0) return ret; } } - if (arizona->pdata.micvdd) - config.init_data = arizona->pdata.micvdd; + if (pdata->init_data) + config.init_data = pdata->init_data; else config.init_data = &micsupp->init_data; diff --git a/include/linux/mfd/arizona/pdata.h b/include/linux/mfd/arizona/pdata.h index 64faeeff698c..43e875f9850c 100644 --- a/include/linux/mfd/arizona/pdata.h +++ b/include/linux/mfd/arizona/pdata.h @@ -12,6 +12,7 @@ #define _ARIZONA_PDATA_H #include +#include #define ARIZONA_GPN_DIR_MASK 0x8000 /* GPN_DIR */ #define ARIZONA_GPN_DIR_SHIFT 15 /* GPN_DIR */ @@ -79,7 +80,7 @@ struct arizona_pdata { int ldoena; /** GPIO controlling LODENA, if any */ /** Regulator configuration for MICVDD */ - struct regulator_init_data *micvdd; + struct arizona_micsupp_pdata micvdd; /** Regulator configuration for LDO1 */ struct regulator_init_data *ldo1; diff --git a/include/linux/regulator/arizona-micsupp.h b/include/linux/regulator/arizona-micsupp.h new file mode 100644 index 000000000000..616842619c00 --- /dev/null +++ b/include/linux/regulator/arizona-micsupp.h @@ -0,0 +1,21 @@ +/* + * Platform data for Arizona micsupp regulator + * + * Copyright 2017 Cirrus Logic + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + */ + +#ifndef ARIZONA_MICSUPP_H +#define ARIZONA_MICSUPP_H + +struct regulator_init_data; + +struct arizona_micsupp_pdata { + /** Regulator configuration for micsupp */ + const struct regulator_init_data *init_data; +}; + +#endif
