This platform data was part of the ambition to support more SoCs, which in turn were never mass produced. Only a name remains of the MFD cell so switch to MFD_CELL_NAME(). Cc: Lee Jones Signed-off-by: Linus Walleij --- Lee: it'd be prefect if you could ACK this so the watchdog people can merge it, it shouldn't collide with any other changes to the PRCMU driver. --- drivers/mfd/db8500-prcmu.c | 13 +------------ drivers/watchdog/ux500_wdt.c | 13 ++----------- include/linux/platform_data/ux500_wdt.h | 18 ------------------ 3 files changed, 3 insertions(+), 41 deletions(-) delete mode 100644 include/linux/platform_data/ux500_wdt.h diff --git a/drivers/mfd/db8500-prcmu.c b/drivers/mfd/db8500-prcmu.c index c1d3e7c116cf..ccf6be922b39 100644 --- a/drivers/mfd/db8500-prcmu.c +++ b/drivers/mfd/db8500-prcmu.c @@ -36,7 +36,6 @@ #include #include #include -#include #include "db8500-prcmu-regs.h" /* Index of different voltages to be used when accessing AVSData */ @@ -2939,18 +2938,8 @@ static struct regulator_init_data db8500_regulators[DB8500_NUM_REGULATORS] = { }, }; -static struct ux500_wdt_data db8500_wdt_pdata = { - .timeout = 600, /* 10 minutes */ - .has_28_bits_resolution = true, -}; - static const struct mfd_cell common_prcmu_devs[] = { - { - .name = "ux500_wdt", - .platform_data = &db8500_wdt_pdata, - .pdata_size = sizeof(db8500_wdt_pdata), - .id = -1, - }, + MFD_CELL_NAME("ux500_wdt"), MFD_CELL_NAME("db8500-cpuidle"), }; diff --git a/drivers/watchdog/ux500_wdt.c b/drivers/watchdog/ux500_wdt.c index 072758106865..40f8cf1cb234 100644 --- a/drivers/watchdog/ux500_wdt.c +++ b/drivers/watchdog/ux500_wdt.c @@ -15,7 +15,6 @@ #include #include #include -#include #include @@ -23,7 +22,6 @@ #define WATCHDOG_MIN 0 #define WATCHDOG_MAX28 268435 /* 28 bit resolution in ms == 268435.455 s */ -#define WATCHDOG_MAX32 4294967 /* 32 bit resolution in ms == 4294967.295 s */ static unsigned int timeout = WATCHDOG_TIMEOUT; module_param(timeout, uint, 0); @@ -80,22 +78,15 @@ static struct watchdog_device ux500_wdt = { .info = &ux500_wdt_info, .ops = &ux500_wdt_ops, .min_timeout = WATCHDOG_MIN, - .max_timeout = WATCHDOG_MAX32, + .max_timeout = WATCHDOG_MAX28, }; static int ux500_wdt_probe(struct platform_device *pdev) { struct device *dev = &pdev->dev; int ret; - struct ux500_wdt_data *pdata = dev_get_platdata(dev); - - if (pdata) { - if (pdata->timeout > 0) - timeout = pdata->timeout; - if (pdata->has_28_bits_resolution) - ux500_wdt.max_timeout = WATCHDOG_MAX28; - } + timeout = 600; /* Default to 10 minutes */ ux500_wdt.parent = dev; watchdog_set_nowayout(&ux500_wdt, nowayout); diff --git a/include/linux/platform_data/ux500_wdt.h b/include/linux/platform_data/ux500_wdt.h deleted file mode 100644 index de6a4ad41e76..000000000000 --- a/include/linux/platform_data/ux500_wdt.h +++ /dev/null @@ -1,18 +0,0 @@ -/* SPDX-License-Identifier: GPL-2.0-only */ -/* - * Copyright (C) ST Ericsson SA 2011 - * - * STE Ux500 Watchdog platform data - */ -#ifndef __UX500_WDT_H -#define __UX500_WDT_H - -/** - * struct ux500_wdt_data - */ -struct ux500_wdt_data { - unsigned int timeout; - bool has_28_bits_resolution; -}; - -#endif /* __UX500_WDT_H */ -- 2.31.1
