controller. Any usage of power domains by the Raspberry Pi
firmware means that Linux usage of the same power domain

ARM: bcm2835: add rpi power domain driver This patch adds support for several power domains on Raspberry Pi, including USB (so it can be enabled even if the bootloader didn't do it), and graphics. This patch is the combined work of Eric Anholt (who wrote USB support inside of the Raspberry Pi firmware driver, and wrote the non-USB domain support) and Alexander Aring (who separated the original USB work out from the firmware driver).

ARM: bcm2835: clarify RASPBERRYPI_FIRMWARE dependency The firmware driver can be a loadable module, but the power domain can only be built-in, so we get a build error in an allmodconfig kernel: :(.text+0x17e59c): undefined reference to `rpi_firmware_property' :(.text+0x17e51c): undefined reference to `rpi_firmware_get' :(.text+0x17e244): undefined reference to `rpi_firmware_property' This changes the dependency to only allow the power domain code to be enabled when the firmware driver is built-in. Other users of the firmware driver may still be loadable modules and not everyone needs the power domains, so we don't change the firmware code. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

soc: bcm: brcmstb: Add support for S2/S3/S5 suspend states (ARM) This commit adds support for the Broadcom STB S2/S3/S5 suspend states on ARM based SoCs. This requires quite a lot of code in order to deal with the different HW blocks that need to be quiesced during suspend: - DDR PHY SHIM - DDR memory controller and sequencer - control processor The final steps of the suspend execute in an on-chip SRAM and there is a little bit of assembly code in order to shut down the DDR PHY PLL and then go into a wfi loop until a wake-up even occurs. Conversely the resume part involves waiting for the DDR PHY PLL to come back up and resume executions where we left. For S3, because of our memory hashing (actual hashing code not included for simplicity, and is bypassed) we need to relocate the writable variables (stack) into SRAM shortly before suspending in order to leave the DRAM untouched and create a reliable hash of its contents. This code has been contributed by Brian Norris initially and has been incrementally fixed and updated to support new chips by a lot of people.
