ARM: mach-shmobile: sh7372 A4R support (v4)
This change adds support for the sh7372 A4R power domain. The sh7372 A4R hardware power domain contains the SH CPU Core and a set of I/O devices including multimedia accelerators and I2C controllers. One special case about A4R is the INTCS interrupt controller that needs to be saved and restored to keep working as expected. Also the LCDC hardware blocks are in a different hardware power domain but have their IRQs routed only through INTCS. So as long as LCDCs are active we cannot power down INTCS because that would risk losing interrupts. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
