From 974cc7b93441a0e78f030495436d1be7eb7c208d Mon Sep 17 00:00:00 2001 From: Pawel Moll Date: Wed, 23 Apr 2014 10:49:31 +0100 Subject: mfd: vexpress: Define the device as MFD cells This patch - finally, after over 6 months! :-( - addresses Samuel's request to split the vexpress-sysreg driver into smaller portions and define the device in a form of MFD cells: * LEDs code has been completely removed and replaced with "gpio-leds" nodes in the tree (referencing dedicated GPIO subnodes in sysreg - bindings documentation updated); this also better fits the reality as some variants of the motherboard don't have all the LEDs populated * syscfg bridge code has been extracted into a separate driver (placed in drivers/misc for no better place) * all the ID & MISC registers are defined as sysconf making them available for other drivers should they need to use them (and also to the user via /sys/kernel/debug/regmap which can be helpful in platform debugging) Signed-off-by: Pawel Moll Acked-by: Lee Jones --- drivers/misc/Kconfig | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'drivers/misc/Kconfig') diff --git a/drivers/misc/Kconfig b/drivers/misc/Kconfig index 8baff0effc7d..d9663ef90ce8 100644 --- a/drivers/misc/Kconfig +++ b/drivers/misc/Kconfig @@ -515,6 +515,15 @@ config SRAM the genalloc API.
