From d0f949e220fdf5ed1033e9f6e80749b05f2e7b70 Mon Sep 17 00:00:00 2001 From: Benjamin Gaignard Date: Fri, 20 Jan 2017 10:15:03 +0100 Subject: mfd: Add STM32 Timers driver This hardware block could at used at same time for PWM generation and IIO timers. PWM and IIO timer configuration are mixed in the same registers so we need a multi fonction driver to be able to share those registers. version 7: - rebase on v4.10-rc2 version 6: - rename files to stm32-timers - rename functions to stm32_timers_xxx version 5: - fix Lee comments about detect function - add missing dependency on REGMAP_MMIO version 4: - add a function to detect Auto Reload Register (ARR) size - rename the structure shared with other drivers version 2: - rename driver "stm32-gptimer" to be align with SoC documentation - only keep one compatible - use of_platform_populate() instead of devm_mfd_add_devices() Signed-off-by: Benjamin Gaignard Acked-by: Rob Herring Signed-off-by: Lee Jones --- drivers/mfd/Kconfig | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'drivers/mfd/Kconfig') diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig index 4ce3b6f11830..d0c14b88b24e 100644 --- a/drivers/mfd/Kconfig +++ b/drivers/mfd/Kconfig @@ -1621,6 +1621,17 @@ config MFD_STW481X in various ST Microelectronics and ST-Ericsson embedded Nomadik series. +config MFD_STM32_TIMERS + tristate "Support for STM32 Timers" + depends on (ARCH_STM32 && OF) || COMPILE_TEST + select MFD_CORE + select REGMAP + select REGMAP_MMIO + help + Select this option to enable STM32 timers driver used + for PWM and IIO Timer.
