Hi Andy,
This series patches ware verified on my github with RK3368 evb and
RK30236 board.

This driver parse the reboot commands like "reboot loader"
and "reboot recovery" to get a boot mode described in the
device tree , then call the corresponding write interfae
to store the boot mode in some place like special register
or ram , which can be read by the bootloader after system
reboot.
This is commonly done on Android based devices, in order to
reboot the device into fastboot or recovery mode.
Changes in v4:
- remove mode-maskrom
- rename mode-fastboot to mode-bootloader to keep compatible with the exiting Android device
- make this driver depends on OF to avoid kbuild test error
Changes in v3:
- descirbe all reboot mode as properity instead of subnode
- scan multi properities
- add mask value for some platform which only use some bits of the register
to store boot mode magic value
- descirbe all reboot mode as property instead of subnode
- add rk3036 support
- descirbe all reboot mode as properity instead of subnode
Changes in v2:
- move to dir drivers/power/reset/
- make syscon-reboot-mode a generic driver
- make this node as a subnode of PMU
- make this node as a subnode of pmugrf
Changes in v1:
- fix the embarrassed compile warning
- correct the maskrom magic number
- check for the normal reboot
- correct the maskrom magic number
- use macro defined in rockchip_boot-mode.h for reboot-mode DT node

dt-bindings: power: reset: add document for reboot-mode driver
power: reset: add reboot mode driver
ARM: dts: rockchip: add syscon-reboot-mode DT node
ARM64: dts: rockchip: add syscon-reboot-mode DT node
