Multiple domains are prepared for the family, this patch prepares the common functions. Signed-off-by: Baoyou Xie <baoyou.xie@linaro.org> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

We don't currently have anything else for drivers/soc to merge, but I'd expect that to change as soon as we can start moving PM code into drivers with the recently posted SRAM changes. Anyways, sent as a separate pull request to make it easy to group the ARM SoC pull requests. * tag 'omap-for-v4.11/drivers-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: soc: ti: wkup_m3_ipc: Drop wait from wkup_m3_rproc_boot_thread Signed-off-by: Olof Johansson <olof@lixom.net>

Secondly a "driver" that attaches to the already existing grf nodes and is able to set static defaults for settings that cannot really be attached to any specific subsystem. Most GRF settings can already be set from drivers using them, but there are some behavioural settings like the mmc/jtag switch that cannot. As the commit message states this is really meant as a last line of defence for things that neither belong to a subsystem nor to the Having this here allows arm64 socs to have this as well and also moves another bit of code out of the arm32 mach-rockchip. * tag 'v4.11-armsoc-drivers1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip: ARM: rockchip: drop rk3288 jtag/mmc switch handling soc: rockchip: add driver handling grf setup dt-bindings: add used but undocumented rockchip grf compatible values soc: rockchip: power-domain: add power domain support for rk3328 dt-bindings: add binding for rk3328 power domains dt-bindings: power: add RK3328 SoCs header for idle-request soc: rockchip: power-domain: Support domain control in hiword-registers Signed-off-by: Olof Johansson <olof@lixom.net>

Therefore all used components are accessed via the syscon provided by the grf nodes or from the sub-devices created through the simple-mfd created from the grf node. Some settings are not used by anything but will need to be set up according to expectations on the kernel side. Best example is the force_jtag setting, which defaults to on and results in the soc switching the pin-outputs between jtag and sdmmc automatically depending on the card-detect status. This conflicts heavily with how the dw_mmc driver expects to do its work and also with the clock-controller, which has most likely deactivated the jtag clock due to it being unused. So far the handling of this setting was living in the mach-rockchip code for the arm32-based rk3288 but that of course doesn't work for arm64 socs and would also look ugly for further arm32 socs. Also always disabling this setting is quite specific to linux and its subsystems, other operating systems might prefer other settings, so that the bootloader cannot really set a sane default for all. So introduce a top-level driver for the grf that handles these settings that need to be a certain way but nobody cares about. Other needed settings might surface in the future and can then be added here, but only as a last option. Ideally general GRF settings should be handled in the driver needing them.
