The #ifdefs are needed to prevent compile errors until the entire ARCH_DAVINCI is converted. Signed-off-by: David Lechner --- v7 changes: - register platform device instead of registering clocks directly - USB PHY clocks now treated as single device instead of registering them separately v6 changes: - rename stuff to match changes in "clk: davinci: New driver for TI DA8XX USB PHY clocks" - take advantage of syscon lookup changes in "mfd: syscon: Add syscon_register() function" arch/arm/mach-davinci/board-da830-evm.c | 8 +++++++- arch/arm/mach-davinci/board-omapl138-hawk.c | 9 +++++++-- arch/arm/mach-davinci/da8xx-dt.c | 8 +++++++- arch/arm/mach-davinci/include/mach/da8xx.h | 1 + arch/arm/mach-davinci/usb-da8xx.c | 26 ++++++++++++++++++++++++-- 5 files changed, 46 insertions(+), 6 deletions(-) diff --git a/arch/arm/mach-davinci/board-da830-evm.c b/arch/arm/mach-davinci/board-da830-evm.c index 3973124..6e77c45 100644 --- a/arch/arm/mach-davinci/board-da830-evm.c +++ b/arch/arm/mach-davinci/board-da830-evm.c @@ -110,6 +110,12 @@ static __init void da830_evm_usb_init(void) { int ret;
