2015-03-11ARM: STi: Add STiH410 SoC supportFabrice GASNIER1-0/+1
This patch adds support to STiH410 SoC. Please note "st,stih410" is already present in device tree. The problem is that it is missing the entry in the match table, and so the L2 cache and other cpus than 0 don't get initialized.

git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v4.0/fixes ARM: OMAP2+: first set of hwmod and PRCM fixes for v4.0-rc This series fixes the following bugs: - a lockdep problem with the OMAP hwmod code; - incorrect PCIe hwmod data for the DRA7xx chips; - the clockdomain handling in the hardreset deassertion code, preventing idle; - the use of an IRQ status register rather than an IRQ enable register in the OMAP4 PRM code.

2015-03-06ARM: dts: OMAP5: fix polling intervals for thermal zonesTero Kristo3-2/+6
OMAP4 has a finer counter granularity, which allows for a delay of 1000ms in the thermal zone polling intervals. OMAP5 has a different counter mechanism, which allows at maximum a 500ms timer. Adjust the cpu thermal zone polling interval accordingly.

2015-03-06ARM: dts: OMAP5: Fix the bypass clock source for dpll_iva and othersRavikumar Kattekola1-4/+37
Fixes 85dc74e9 (ARM: dts: omap5 clock data) On OMAP54xx, For DPLL_IVA, the ref clock(CLKINP) is connected to sys_clk1 and the bypass input(CLKINPULOW) is connected to iva_dpll_hs_clk_div clock. But the bypass input is not directly routed to bypass clkout instead both CLKINP and CLKINPULOW are connected to bypass clkout via a mux. This mux is controlled by the bit - CM_CLKSEL_DPLL_IVA[23]:DPLL_BYP_CLKSEL and it's POR value is zero which selects the CLKINP as bypass clkout. which means iva_dpll_hs_clk_div is not the bypass clock for dpll_iva_ck Fix this by adding another mux clock as parent in bypass mode. This design is common to most of the PLLs and the rest have only one bypass clock.

2015-03-03pm: at91: Workaround DDRSDRC self-refresh bug with LPDDR1 memories.Peter Rosin1-5/+38
The DDRSDR controller fails miserably to put LPDDR1 memories in self-refresh. Force the controller to think it has DDR2 memories during the self-refresh period, as the DDR2 self-refresh spec is equivalent to LPDDR1, and is correctly implemented in the controller. Assume that the second controller has the same fault, but that is untested.

2015-03-03pm: at91: pm_slowclock: fix suspend/resume hang up in timeoutsSylvain Rochet1-29/+4
Removed timeout on XTAL, PLL lock and Master Clock Ready, hang if something went wrong instead of continuing in unknown condition. There is not much we can do if a PLL lock never ends, we are running in SRAM and we will not be able to connect back the sdram or ddram in order to be able to fire up a message or just panic. As a bonus, not decounting the timeout register in slow clock mode reduce cumulated suspend time and resume time from ~17ms to ~15ms.

2015-03-01ARM: OMAP4+: PRM: fix omap4 version of prm_save_and_clear_irqenTero Kristo1-2/+2
This was incorrectly reading the irq status registers during the save and clear, instead of the irq enable. This worked because there is only one user for the prcm interrupts currently, namely the io-chain. Whenever the function was called, an io-chain interrupt was both pending and enabled.

2015-03-01ARM: OMAP2+: hwmod: fix deassert hardreset clkdm usecountingTero Kristo1-5/+4
Deasserting hardreset increases the usecount for the hwmod parent clockdomain always, however usecount is only decreased at end in certain error cases. This causes software supervised clockdomains to remain always on, preventing idle. Fixed by always releasing the hwmods clockdomain parent when exiting the function.

2015-02-28mm: add missing __PAGETABLE_{PUD,PMD}_FOLDED definesKirill A. Shutemov6-0/+10
Core mm expects __PAGETABLE_{PUD,PMD}_FOLDED to be defined if these page table levels folded. Usually, these defines are provided by <asm-generic/pgtable-nopmd.h> and <asm-generic/pgtable-nopud.h>. But some architectures fold page table levels in a custom way. They need to define these macros themself. This patch adds missing defines. The patch fixes mm->nr_pmds underflow and eliminates dead __pmd_alloc() and __pud_alloc() on architectures without these page table levels. Signed-off-by: Kirill A.

2015-02-28x86: Init per-cpu shadow copy of CR4 on 32-bit CPUs tooSteven Rostedt1-0/+6
Commit: 1e02ce4cccdc ("x86: Store a per-cpu shadow copy of CR4") added a shadow CR4 such that reads and writes that do not modify the CR4 execute much faster than always reading the register itself. The change modified cpu_init() in common.c, so that the shadow CR4 gets initialized before anything uses it. Unfortunately, there's two cpu_init()s in common.c. There's one for 64-bit and one for 32-bit. The commit only added the shadow init to the 64-bit path, but the 32-bit path needs the init too.
