2018-10-04ARM: dts: da850-lego-ev3: slow down A/DC as much as possibleDavid Lechner1-1/+2
Due to the electrical design of the A/DC circuits on LEGO MINDSTORMS EV3, if we are reading analog values as fast as possible (i.e. using DMA to service the SPI) the A/DC chip will read incorrect values - as much as 0.1V off when the SPI is running at 10MHz. (This has to do with the capacitor charge time when channels are muxed in the A/DC.) This patch slows down the SPI as much as possible (if CPU is at 456MHz, SPI runs at 1/2 of that, so 228MHz and has a max prescalar of 256, so we could get ~891kHz, but we're just rounding it to 1MHz). We also use the max allowable value for WDELAY to slow things down even more. These changes reduce the error of the analog values to about 5mV, which is tolerable. Commits a3762b13a596 ("spi: spi-davinci: Add support for SPI_CS_WORD") and e2540da86ef8 ("iio: adc: ti-ads7950: use SPI_CS_WORD to reduce CPU usage") introduce changes that allow DMA transfers to be used, so this slow down is needed now.

2018-10-04ARM: 8801/1: makefile: use ARMv3M mode for RiscPCJason A. Donenfeld1-1/+1
The purpose of CONFIG_CPU_32v3 is to avoid ldrh/strh on the RiscPC, which is pretty much an ARMv4 device, except its bus will choke on the half-words. The way to make the C compiler not output ldrh/strh is with -march=armv3, which doesn't support them in the ISA. However, this prevents certain cryptography code from working that uses instructions like umull. Fortunately there's also -march=armv3m that does support those, making it possible to continue assembling optimized cryptography routines for our beloved RiscPC. Signed-off-by: Jason A.

2018-10-04ARM: 8800/1: use choice for kernel unwindersStefan Agner1-16/+28
While in theory multiple unwinders could be compiled in, it does not make sense in practise. Use a choice to make the unwinder selection mutually exclusive and mandatory. Already before this commit it has not been possible to deselect FRAME_POINTER. Remove the obsolete comment. Furthermore, to produce a meaningful backtrace with FRAME_POINTER enabled the kernel needs a specific function prologue: mov ip, sp stmfd sp!, {fp, ip, lr, pc} sub fp, ip, #4 To get to the required prologue gcc uses apcs and no-sched-prolog. This compiler options are not available on clang, and clang is not able to generate the required prologue. Make the FRAME_POINTER config symbol depending on !clang.

2018-10-03KVM: arm/arm64: Rename kvm_arm_config_vm to kvm_arm_setup_stage2Marc Zyngier1-1/+5
VM tends to be a very overloaded term in KVM, so let's keep it to describe the virtual machine. For the virtual memory setup, let's use the "stage2" suffix.

2018-10-03kvm: arm64: Set a limit on the IPA sizeSuzuki K Poulose1-0/+2
So far we have restricted the IPA size of the VM to the default value (40bits). Now that we can manage the IPA size per VM and support dynamic stage2 page tables, we can allow VMs to have larger IPA. This patch introduces a the maximum IPA size supported on the host. This is decided by the following factors : 1) Maximum PARange supported by the CPUs - This can be inferred from the system wide safe value. 2) Maximum PA size supported by the host kernel (48 vs 52) 3) Number of levels in the host page table (as we base our stage2 tables on the host table helpers). Since the stage2 page table code is dependent on the stage1 page table, we always ensure that : Number of Levels at Stage1 >= Number of Levels at Stage2 So we limit the IPA to make sure that the above condition is satisfied. This will affect the following combinations of VA_BITS and IPA for different page sizes. Host configuration | Unsupported IPA ranges 39bit VA, 4K | [44, 48] 36bit VA, 16K | [41, 48] 42bit VA, 64K | [47, 52] Supporting the above combinations need independent stage2 page table manipulation code, which would need substantial changes. We could purse the solution independently and switch the page table code once we have it ready.

2018-10-03mtd: rawnand: Create a legacy struct and move ->IO_ADDR_{R, W} thereBoris Brezillon9-17/+18
We regularly have new NAND controller drivers that are making use of fields/hooks that we want to get rid of but can't because of all the legacy drivers that we might break if we do. So, instead of removing those fields/hooks, let's move them to a sub-struct which is clearly documented as deprecated. We start with the ->IO_ADDR_{R,W] fields.

2018-10-03mtd: rawnand: plat_nand: Pass a nand_chip object to all platform_nand_ctrl hooksBoris Brezillon14-47/+32
Let's make the raw NAND API consistent by patching all helpers and hooks to take a nand_chip object instead of an mtd_info one or remove the mtd_info object when both are passed. In order to do that, we first need to update the platform_nand_ctrl hooks to take a nand_chip object instead of an mtd_info. We add temporary plat_nand_xxx() wrappers to the do the mtd -> chip conversion, but those will be dropped when patching nand_chip hooks to take a nand_chip object.
