ARM: shmobile: Break out R-Car SYSC PM code Break out the R-Car SYSC power management code from the r8a7779 SoC code. With this new shared R-Car SYSC code base it is possible to hook in Generation 2 SoCs as well. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

ARM: shmobile: R-Car: Shrink rcar_sysc_ch size Shrink the individual fields in struct rcar_sysc_ch, as unsigned long or int is overkill: - chan_offs contains a register offset relative to a base value (< 512), - chan_bit and isr_bit contain bit indices (0-31). This reduces the size of each instance from 3 (4 on 64-bit) 32-bit words to 1 32-bit word.
