2021-02-03ARM: dts: lpc32xx: Revert set default clock rate of HCLK PLLAlexandre Belloni
This reverts commit c17e9377aa81664d94b4f2102559fcf2a01ec8e7. The lpc32xx clock driver is not able to actually change the PLL rate as this would require reparenting ARM_CLK, DDRAM_CLK, PERIPH_CLK to SYSCLK, then stop the PLL, update the register, restart the PLL and wait for the PLL to lock and finally reparent ARM_CLK, DDRAM_CLK, PERIPH_CLK to HCLK PLL. Currently, the HCLK driver simply updates the registers but this has no real effect and all the clock rate calculation end up being wrong. This is especially annoying for the peripheral (e.g. UARTs, I2C, SPI).

2021-02-03ARM: dts: sun7i: a20: bananapro: Fix ethernet phy-modeHermann Lauer
BPi Pro needs TX and RX delay for Gbit to work reliable and avoid high packet loss rates. The realtek phy driver overrides the settings of the pull ups for the delays, so fix this for BananaPro. Fix the phy-mode description to correctly reflect this so that the implementation doesn't reconfigure the delays incorrectly. This happened with commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx delay config").

2021-02-01ARM: 9050/1: Kconfig: Select ARCH_HAVE_NMI_SAFE_CMPXCHG where possibleDaniel Thompson
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 Murzin
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 Uytterhoeven
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.

2021-02-01ARM: 9039/1: assembler: generalize byte swapping macro into rev_lArd Biesheuvel
Take the 4 instruction byte swapping sequence from the decompressor's head.S, and turn it into a rev_l GAS macro for general use. While at it, make it use the 'rev' instruction when compiling for v6 or later.

2021-01-31ARM: dts: sunxi: Rename nmi_intc to r_intcSamuel Holland
The R_INTC block controls more than just the NMI, and it is a different hardware block than the NMI INTC found in some other Allwinner SoCs, so the label "nmi_intc" is inaccurate. Name it "r_intc" to match the compatible and to match the few references in the vendor documentation.

While the USB PHY Device Tree mandates that the name of the ID detect pin should be usb0_id_det-gpios, a significant number of device tree use usb0_id_det-gpio instead. This was functional because the GPIO framework falls back to the gpio suffix that is legacy, but we should fix this.

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 Stach
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>
