2017-07-27ARM: ep93xx: normalize clk APIAlexander Sverdlin
It's a combination of the patch from Arnd Bergmann, which added empty stubs for clk_round_rate() and clk_set_parent() and a working trivial implementation of clk_get_parent(). The later is required for ADC driver. Signed-off-by: Alexander Sverdlin <alexander.sverdlin@gmail.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2017-07-27Merge branch 'parisc-4.13-3' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux Pull parisc fixes from Helge Deller: - The majority of lines changed are due to regenerated defconfig files. - The support for the Page Deallocation Table (PDT) which was merged in the merge window for 4.13 contained a bug which crashes the kernel if a bad page is reported by firmware. This is now fixed and the kernel messages will show which memory slot holds the broken DIMM. - Commit 3a166fc2d4ef ("kbuild: handle libs-y archives separately from built-in.o archives") broke linking the parisc kernel due to millicode symbols which can't be reached then any longer. This was fixed by modifying the parisc vmlinux.lds linker script. - If the stack checker panics on stack overflow, avoid recursive panics. - Some parisc machines can't physically power off and thus instead start after some time to flood the console by presumably detected soft lockups. Avoid this by disabling the lockup detectors before entering the endless for-next loop. - Dave Anglin provided fixes which prevents TLB speculation on flushed pages on PA8800/PA9000 CPUs. - Arvind Yadav sent a trivial patch to constify the attribute_group structure in our firmware on-board-flash storage driver (pdc_stable.c) * 'parisc-4.13-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Extend disabled preemption in copy_user_page parisc: Prevent TLB speculation on flushed pages on CPUs that only support equivalent aliases parisc: Suspend lockup detectors before system halt parisc: Show DIMM slot number which holds broken memory module parisc: Add function to return DIMM slot of physical address parisc: Fix crash when calling PDC_PAT_MEM PDT firmware function parisc: regenerate defconfig files parisc: pdc_stable: constify attribute_group structures. parisc: Merge millicode routines via linker script parisc: Disable further stack checks when panic occurs during stack check

2017-07-27ARM: shmobile: rcar-gen2: Add support for CPG/MSSR bindingsGeert Uytterhoeven
When using the new CPG/MSSR bindings, there is no longer a "renesas,rcar-gen2-cpg-clocks" node, and the code to obtain the external clock crystal frequency falls back to a default of 20 MHz. While this is correct for all upstream R-Car Gen2 and RZ/G1 boards, this is not necessarily the case for out-of-tree third party boards. Add support for finding the external clock crystal oscillator on RZ/G1M, and on R-Car H2, M2-W, and M2-N using the new CPG/MSSR bindings, through the corresponding "renesas,r8a77xx-cpg-mssr" nodes. Note that this is not needed on R-Car V2H and E2, and on RZ/G1E, as on those SoCs the arch_timer and generic counter clock is derived from the ZS clock instead.
