2021-02-02ARM: dts: mmp3-dell-ariel: Replace SSP2 with spi-gpioLubomir Rintel1-1/+12
The firmware leaves the pins in GPIO mode. Until we have a proper pinmux driver hooked on we just need to bitbang SPI. No big deal, this is just used for the power button and performance is not important.

2021-02-02ARM: dts: mmp3-dell-ariel: Add the power button nodeLubomir Rintel1-1/+9
This adds support for the power button attached to the Embedded Controller on a Dell Wyse 3020 "Ariel" board. However, while the EC itself is controlled via I2C, the input capability for the power button acts as a separate device attached to the SPI, hence it has a separate device node.

2021-02-01ARM: 9050/1: Kconfig: Select ARCH_HAVE_NMI_SAFE_CMPXCHG where possibleDaniel Thompson1-0/+1
Currently ARCH_HAVE_NMI_SAFE_CMPXCHG is not set on Arm systems and this makes it impossible to enable features such as ftrace histogram triggers on Arm platforms. Most Arm systems are NMI safe simply because there is no NMI but this isn't universally true meaning we cannot set ARCH_HAVE_NMI_SAFE_CMPXCHG for all Arm devices. However the load/store exclusive implementation of cmpxchg is NMI-safe and this implementation is used ARMv6k and later. Let's select ARCH_HAVE_NMI_SAFE_CMPXCHG for these systems. Note that ARMv6 uses load/store exclusive for 32-bit cmpxchg but relies on interrupt masking for 8- and 16-bit operations. This patch is conservative and does not change behaviour for CPU_V6.

2021-02-01ARM: 9046/1: decompressor: Do not clear SCTLR.nTLSMD for ARMv7+ coresVladimir Murzin1-2/+2
It was observed that decompressor running on hardware implementing ARM v8.2 Load/Store Multiple Atomicity and Ordering Control (LSMAOC), say, as guest, would stuck just after: Uncompressing Linux... done, booting the kernel. The reason is that it clears nTLSMD bit when disabling caches: nTLSMD, bit [3] When ARMv8.2-LSMAOC is implemented: No Trap Load Multiple and Store Multiple to Device-nGRE/Device-nGnRE/Device-nGnRnE memory. 0b0 All memory accesses by A32 and T32 Load Multiple and Store Multiple at EL1 or EL0 that are marked at stage 1 as Device-nGRE/Device-nGnRE/Device-nGnRnE memory are trapped and generate a stage 1 Alignment fault. 0b1 All memory accesses by A32 and T32 Load Multiple and Store Multiple at EL1 or EL0 that are marked at stage 1 as Device-nGRE/Device-nGnRE/Device-nGnRnE memory are not trapped. This bit is permitted to be cached in a TLB. This field resets to 1. Otherwise: Reserved, RES1 So as effect we start getting traps we are not quite ready for. Looking into history it seems that mask used for SCTLR clear came from the similar code for ARMv4, where bit[3] is the enable/disable bit for the write buffer. That not applicable to ARMv7 and onwards, so retire that bit from the masks.

2021-02-01ARM: 9045/1: uncompress: Validate start of physical memory against passed DTBGeert Uytterhoeven4-7/+172
Currently, the start address of physical memory is obtained by masking the program counter with a fixed mask of 0xf8000000. This mask value was chosen as a balance between the requirements of different platforms. However, this does require that the start address of physical memory is a multiple of 128 MiB, precluding booting Linux on platforms where this requirement is not fulfilled. Fix this limitation by validating the masked address against the memory information in the passed DTB. Only use the start address from DTB when masking would yield an out-of-range address, prefer the traditional method in all other cases. Note that this applies only to the explicitly passed DTB on modern systems, and not to a DTB appended to the kernel, or to ATAGS. The appended DTB may need to be augmented by information from ATAGS, which may need to rely on knowledge of the start address of physical memory itself. This allows to boot Linux on r7s9210/rza2mevb using the 64 MiB of SDRAM on the RZA2MEVB sub board, which is located at 0x0C000000 (CS3 space), i.e. not at a multiple of 128 MiB.

The build robots have discovered that uncompress debugging and semihosting does not play well together. This is due to many factors but in general semihosting debug needs to be rewritten to work the same way as any LL_DEBUG, e.g. with a header in arch/arm/include/debug/semihosting.S This is a long term solution and needs testing on real hardware and/or software models using semihosting.

This adds a "HPA1" prefix to the amplifiers on both audio cards, this is done in order to get more consistency for userspace running on RDU2 and RDU3, where we have two amplifiers on a single card device in the "Zest" configuration. Also adjust the card names to the new standard expected by userspace.

2021-01-30ARM: dts: imx6: RDU2: only trigger IRQ on falling edge ucs1002 ALERT pinLucas Stach1-1/+1
The ALERT signaling happens on the falling edge of the signal, as rising edge doesn't really have any notion, as it may happen much later (due to shared IRQ line) or too early if the chip resolves the fault itself. So only trigger the IRQ on the edge we are actually interested in. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2021-01-30ARM: dts: imx6: RDU2: enable RMI4 reduced reportingLucas Stach1-0/+2
To use the reduced reporting mode the threshold values need to be set explicitly. Configure the threshold to be less than 0.5% of the full touchscreen range.

2021-01-29ARM: tegra: ouya: Fix eMMC on specific bootloadersPeter Geis1-2/+2
Ouya fails to detect the eMMC module when booted via certain bootloaders. Fastboot and hard-kexec bootloaders fail while u-boot does not. It was discovered that the issue manifests if the sdmmc4 alternate configuration clock pin is input disabled. Ouya uses sdmmc4 in the primary pin configuration. It is unknown why this occurs, though it is likely related to other eMMC limitations experienced on Ouya. For now, fix it by enabling input on cam_mclk_pcc0.
