This release cycle the diffstat is quite nice, in that we're removing 3x the amount of code that's being added.

There's also removal of display initialization code for OMAP that is no longer needed.

Device tree nodes for each power domain should use generic "power-domain" name, so using it as a domain name doesn't give much benefits. This patch adds support for human readable names defined in 'label' property. Such names are visible to userspace and makes debugging much easier. When no 'label' property is found, driver keeps using the name constructed from full node name.

Some extensions to the power-domain driver to support domains in hiword registers (write-mask in upper 16bit) and domain-definitions for the rk3328 soc. 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>

2017-01-06soc: rockchip: add driver handling grf setupHeiko Stuebner3-0/+145
The General Register Files are an area of registers containing a lot of single-bit settings for numerous components as well full components like usbphy control. 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.

Pull clk updates from Stephen Boyd: "This is a fairly quiet release. We don't have any patches to the core framework. The only patch that can even be considered "core" adds another clk_get() variant. The rest of the changes are in drivers for various SoCs, and we have a few bits for ARM shmobile architecture code (dts and mach) due to the dependency we're breaking between shmobile architecture code and its clk driver. Those shmobile bits have also been pulled into arm-soc tree.

We get the following warning with the driver is compiled in: WARNING: modpost: Found 1 section mismatch(es). To see full details build your kernel with: 'make CONFIG_DEBUG_SECTION_MISMATCH=y' With CONFIG_DEBUG_SECTION_MISMATCH enabled, the details are reported: WARNING: vmlinux.o(.text+0x55d014): Section mismatch in reference from the function fsl_guts_probe() to the function .init.text:of_flat_dt_get_machine_name() The function fsl_guts_probe() references the function __init of_flat_dt_get_machine_name(). This is often because fsl_guts_probe lacks a __init annotation or the annotation of of_flat_dt_get_machine_name is wrong. This patch fixes the issue by using the normal DT/OF API rather than the of_flat_* one.
