This driver register pm_power_off with snvs power off function. If your boards NOT use PMIC_ON_REQ to turn on/off external pmic, or use other pin to do, please disable the driver in dts, otherwise, your pm_power_off maybe overwrote by this driver. Signed-off-by:

The newly introduced LS1021A SoC selects CONFIG_SOC_FSL, which is originally symbol used for the PowerPC based platforms and guards lots of code that does not build on ARM. This breaks allmodconfig, so let's remove it for now, until either all those drivers are fixed or they use a dependency on IMX instead. Signed-off-by:

With the clock assignment device tree changes, the clocks get initialized properly but the search for those clocks fails with errors: [ 0.000000] i.MX clk 4: register failed with -17 [ 0.000000] i.MX clk 5: register failed with -17 This is because the module can't find those clocks anymore, and tries to initialize fixed clocks with the same name. Get the clock modules input clocks from the assigned clocks by default by using of_clk_get_by_name(). If this function returns not a valid clock, fall back to the old behaviour and search the input clock from the device tree's /clocks/$name node. Signed-off-by:

The ARM clock is a virtual clock feeding the ARM partition of the SoC. It controls multiple other clocks to ensure the right sequencing when cpufreq changes the CPU clock rate. Signed-off-by:

This implements a virtual clock used to abstract away all the steps needed in order to change the ARM clock, so we don't have to push all this clock handling into the cpufreq driver. While it will be used for i.MX53 at first it is generic enough to be used on i.MX6 later on. Signed-off-by:

Add the ARM Global Timer as clocksource/scheduler clock option and use it as default scheduler clock. This leaves the PIT timer for other users e.g. the secondary Cortex-M4 core. Also, the Global Timer has double the precission (running at pheripheral clock compared to IPG clock) and a 64-bit incrementing counter register. We still keep the PIT timer as an secondary option in case the ARM Global Timer is not available. Signed-off-by:

For LPDDR2 platform, no need to enable weak2P5 in DSM mode, it can be pulled down to save power(~0.65mW). And per design team's recommendation, we should disconnect VDDHIGH and SNVS in DSM mode on i.MX6SL. Signed-off-by:

As the DDR/IO and MMDC setting are different on LPDDR2 and DDR3, we used cpu type to decide how to do these settings in suspend before which is NOT flexible, take i.MX6SL for example, although it has LPDDR2 on EVK board, but users can also use DDR3 on other boards, so it is better to read the DDR type from MMDC then decide how to do related settings.

The i.MX fixes for 3.18, 2nd round: - Fix a regression on Vybrid platform which is caused by commit dc4805c2 (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3 driver), and results in a missing configuration on PLL clocks. - Fix a regression with i.MX defconfig files where CONFIG_SPI option gets lost accidentally.

Since 64546e9f ("ARM: imx_v6_v7_defconfig updates") and commit 0650f855 ("ARM: imx_v4_v5_defconfig: Select CONFIG_IMX_WEIM") CONFIG_SPI selection was dropped by savedefconfig for imx_v4_v5_defconfig and imx_v6_v7_defconfig. In order to keep the same behaviour as previous kernel versions and avoid regressions, let's add CONFIG_SPI option back. Signed-off-by:

So far, the required PLL's (PLL1/PLL2/PLL5) have been initialized by boot loader and the kernel code defined fixed rates according to those default configurations. Beginning with the USB PLL7 the code started to initialize the PLL's itself (using imx_clk_pllv3). However, since commit dc4805c2 (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3 driver) imx_clk_pllv3 no longer takes care of the ENABLE and BYPASS bits, hence the USB PLL were not configured correctly anymore. This patch not only fixes those USB PLL's, but also makes use of the imx_clk_pllv3 for all PLL's and alignes the code with the PLL support of the i.MX6 series. Signed-off-by:

Pull MTD fixes from Brian Norris: "Three main MTD fixes for 3.18: - A regression from 3.16 which was noticed in 3.17. With the restructuring of the m25p80.c driver and the SPI NOR library framework, we omitted proper listing of the SPI device IDs. This means m25p80.c wouldn't auto-load (modprobe) properly when built as a module. For now, we duplicate the device IDs into both modules. - The OMAP / ELM modules were depending on an implicit link ordering. Use deferred probing so that the new link order (in 3.18-rc) can still allow for successful probing. - Fix suspend/resume support for LH28F640BF NOR flash" * tag 'for-linus-20141102' of git://git.infradead.org/linux-mtd: mtd: cfi_cmdset_0001.c: fix resume for LH28F640BF chips mtd: omap: fix mtd devices not showing up mtd: m25p80,spi-nor: Fix module aliases for m25p80 mtd: spi-nor: make spi_nor_scan() take a chip type name, not spi_device_id mtd: m25p80: get rid of spi_get_device_id -

The sk_prot is irda's own set of protocol handlers, so irda should statically know what that function is anyway, without using an indirect pointer. And as it happens, we know *exactly* what that pointer is statically: it's NULL, because irda doesn't define a disconnect operation. So calling that function is doubly wrong, and will just cause an oops. Reported-by:

In order to access the shadow VMCS, we need to load it. At this point, vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If we now get preempted by Linux, vmx_vcpu_put and, on return, the vmx_vcpu_load will work against the wrong vmcs. That can cause copy_shadow_to_vmcs12 to corrupt the vmcs12 state. Fix the issue by disabling preemption during the copy operation. copy_vmcs12_to_shadow is safe from this issue as it is executed by vmx_vcpu_run when preemption is already disabled before vmentry. This bug is exposed by running Jailhouse within KVM on CPUs with shadow VMCS support. Jailhouse never expects an interrupt pending vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12 is preempted, the active VMCS happens to have the virtual interrupt pending flag set in the CPU-based execution controls.

Commit d1442d85 ("KVM: x86: Handle errors when RIP is set during far jumps") introduced a bug that caused the fix to be incomplete. Due to incorrect evaluation, far jump to segment with L bit cleared (i.e., 32-bit segment) and RIP with any of the high bits set (i.e, RIP[63:32] != 0) set may not trigger #GP. As we know, this imposes a security problem. In addition, the condition for two warnings was incorrect. Fixes: d1442d85Reported-by:
