Now that the Amstrad Delta on-board latches have been converted to GPIO devices, use the generic driver to control on-board LEDs which hang off those latches.
Depends on patch 2/7 "ARM: OMAP1: ams-delta: convert latches to basic_mmio_gpio" Signed-off-by: Janusz Krzysztofik <[email protected]> --- Changes against initial version: * no functional changes, * refreshed on top of v2 of patch 2/7, * dropped leading underscores from local symbols, variable and function names (no namespace conflicts expected). arch/arm/mach-omap1/Kconfig | 1 + arch/arm/mach-omap1/board-ams-delta.c | 87 +++++++++++--------- arch/arm/plat-omap/include/plat/board-ams-delta.h | 19 ----- 3 files changed, 49 insertions(+), 58 deletions(-) diff --git a/arch/arm/mach-omap1/Kconfig b/arch/arm/mach-omap1/Kconfig index d2606b1..ed7e864 100644 --- a/arch/arm/mach-omap1/Kconfig +++ b/arch/arm/mach-omap1/Kconfig @@ -156,6 +156,7 @@ config MACH_AMS_DELTA depends on ARCH_OMAP1 && ARCH_OMAP15XX select FIQ select GPIO_GENERIC_PLATFORM + select LEDS_GPIO_REGISTER help Support for the Amstrad E3 (codename Delta) videophone.
