Fix this by introducing two new callback suspend_mem and suspend_standby. If a bus or drivers does not need to care about this distinction we fallback to suspend. This will allow to do not update the current bus or drivers. This is needed as example by at91 OHCI, UDC and atmel serial Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD ---------------------------------------------------------------- Jean-Christophe PLAGNIOL-VILLARD (6): pm: add suspend_mem and suspend_standby support platform: pm: add suspend_mem and suspend_standby support tty: atmel_serial: switch pm ops usb: ohci-at91: switch pm ops usb: at91_ude: switch pm ops arm: at91: drop at91_suspend_entering_slow_clock arch/arm/mach-at91/include/mach/board.h | 3 --- arch/arm/mach-at91/pm.c | 24 ------------------------ drivers/base/platform.c | 40 ++++++++++++++++++++++++++++++++++++++++ drivers/base/power/main.c | 12 ++++++++++++ drivers/tty/serial/atmel_serial.c | 52 +++++++++++++++++++++++++++------------------------- drivers/usb/gadget/at91_udc.c | 34 +++++++++++++++++++++++----------- drivers/usb/host/ohci-at91.c | 38 ++++++++++++++++++++++++-------------- include/linux/platform_device.h | 6 ++++++ include/linux/pm.h | 9 +++++++++ kernel/power/suspend.c | 16 ++++++++++++++-- 10 files changed, 155 insertions(+), 79 deletions(-) Best Regards, J.
