This adds the new board-specific clock init in mach-davinci/dm355.c using the new common clock framework drivers. The #ifdefs are needed to prevent compile errors until the entire ARCH_DAVINCI is converted. Also clean up the #includes since we are adding some here. Signed-off-by: David Lechner <david@lechnology.com> --- v8 changes: - none v7 changes: - add clock platform device declarations - register platform devices instead of registering clocks directly - add davinci prefix to commit description v6 changes: - add blank lines between function calls arch/arm/mach-davinci/board-dm355-evm.c | 2 + arch/arm/mach-davinci/board-dm355-leopard.c | 2 + arch/arm/mach-davinci/davinci.h | 1 + arch/arm/mach-davinci/dm355.c | 88 +++++++++++++++++++++++++---- 4 files changed, 81 insertions(+), 12 deletions(-)
