The number of register we can safely pass to at91_pm_suspend_in_sram is limited. Instead, pass the address to the at91_pm_data structure. The offsets are automatically generated to avoid hardcoding them. Acked-by: Wenyou Yang <wenyou.yang@atmel.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
