This series adds the plain basic support for booting a bare
kernel on the RZ/N1D-DB Board. It's been trimmed to the strict
minimum as a 'base', further patches that could add the
rest of the support.
Note on the clock driver: Current usage of the clocks on Linux
involves Linux 'claiming' all of them, disabling the one it doesn't
need and so on.
On *this* architecture it can't be done, there is at least one other
OS running on the CM3 core that claims it's own clock; Linux can claim
some others but definitely not start disabling stuff it isn't supposed to.
Thanks for the comments on the previous versions!
v9:
+ Added Reviewed mentions as appropriate.
+ Tweaked the detection code for clocks that are already in use.
(Now check the reset bits, as some clocks gates are marked as 'enabled'
when still in reset (!)).
+ Added external clocks to the sysctrl node.
+ Reworked the clock driver to be a platform one, not an OF one.
v8:
+ Added Reviewed mentions as appropriate.
+ Moved some of the clocks #defines into the driver
+ Tweaked the pointer arithmetics in the clock driver.
+ Removed clk_readl/writel
+ Use CLK_IS_CRITICAL instead of my own flag
+ Also added that critical section to the dualgate object.
+ Few other nitpick fixed.
+ Rebased on next-20180604
v7:
+ Removed mention of 'rz[/]n1' from everywhere.
+ Removed unwanted documentation.
+ Renamed clock node back to sysctrl.
+ Renamed rzn1-clocks.h to r9a06g032-sysctrl.h to match
+ Made the clock driver claim the sysctrl node.
+ Fixed a couple of 'sparse' warning in the clock driver.
v6:
+ Fix for suggestion by Geert Uytterhoeven
+ Removed "renesas,rzn1" from the board bindings
+ Removed patches already merged.
+ Removed reboot driver
+ Added a whole clock infrastructure.
+ Rebased on next-20180517
v5:
+ Given the problems I have with getting in some structure around the
sysctrl block, I've removed the MFD, I've now attached the reboot
driver on it's own pair of registers.
+ Rebased on next-20180417
v4:
+ Fixes for suggestions by Simon Horman
+ Fixes for suggestions by Jacopo Mondi
+ Fixes for suggestions by Geert Uytterhoeven
+ Renamed the r9a06g0xx.dtsi file, given up on trying to get a family
common file in, so dropped potential RZ/N1S support and now only
focus on RZ/N1D for this patchset.
+ Added 'always-on' to the architected timer node, because it is.
+ Added ARCH_R9A06G032, to match others patterns like RCAR
+ Sorted the .dts files, added empty lines as required.
+ Fixed patch prefixes to match git-log for bindings&dts
+ Merged board .dts & Makefile changes together
+ Rebased on next-20180410
v3:
+ Fixes for suggestions by Geert Uytterhoeven
+ Removed SoC Specific renesas,r9a06g032-xxx, as it's not needed for now.
+ Kept renesas,rzn1 as a family/generic for this family.
+ Fixed a couple of the commit messages.
+ Added Geert's Reviewed-By where appropriate.
v2:
+ Fixes for suggestions by Simon Horman
+ Fixes for suggestions by Rob Herring
+ Fixes for suggestions by Geert Uytterhoeven
+ Removed the mach file
+ Added a MFD base for the sysctrl block
+ Added a regmap based sub driver for the reboot handler
+ Renamed the files to match shmobile conventions
+ Adapted the compatible= strings to reflect 'family' vs 'part'
distinction.
+ Removed the sysctrl.h file entirelly.
+ Fixed every warnings from the DTC compiler on W=12 mode.
+ Split the device-tree patches from the code.
