git://git.kernel.org/pub/scm/linux/kernel/git/mani/linux-actions into arm/dt Actions Semi ARM DT changes for v5.12: Updates to the existing S500 ARM SoC. Support has been added for CMU (Clock Management Unit), Reset controller, DMA, Pinctrl/GPIO, MMC, I2C and SIRQ (interrupt controller). Since the CMU support is added, the dummy fixed clock used for the UART controller has been removed for all S500 based boards and proper UART clock from CMU is used. Added uSD support and I2C pinctrl configuration for Roseapplepi board based on S500 SoC. This will make the board boot mainline with a distro from uSD card. The I2C pinctrl config is added specifically for the PMIC which is currently under review. * tag 'actions-arm-dt-for-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/mani/linux-actions: arm: dts: owl-s500-roseapplepi: Add I2C pinctrl configuration arm: dts: owl-s500-roseapplepi: Add uSD support arm: dts: owl-s500: Add SIRQ controller arm: dts: owl-s500: Add I2C support arm: dts: owl-s500: Add MMC support arm: dts: owl-s500: Add pinctrl & GPIO support arm: dts: owl-s500: Add DMA controller arm: dts: owl-s500: Add Reset controller arm: dts: owl-s500: Set CMU clocks for UARTs arm: dts: owl-s500: Add Clock Management Unit Link: https://lore.kernel.org/r/20210205050346.GA7619@thinkpad Signed-off-by: Arnd Bergmann <arnd@arndb.de>

This is caused by machine_kexec() trying to set the kernel text to be read/write, so it can poke values into the relocation code before copying it - and an interrupt occuring which changes the page tables. The subsequent writes then hit read-only sections that trigger a data abort resulting in the above oops. Fix this by copying the relocation code, and then writing the variables into the destination, thereby avoiding the need to make the kernel text read/write.

Without DT aliases, the numbering of mmc interfaces is unpredictable. Adding them makes it possible to refer to devices consistently. The popular suggestion to use UUIDs obviously doesn't work with a blank device fresh from the factory.

2021-02-03ARM: dts: meson: add the AO ARC remote processorMartin Blumenstingl3-0/+49
The 32-bit Amlogic Meson SoCs embed an ARC processor in the Always-On power domain which is typically used for managing system suspend. The memory for this ARC core is taken from the AHB SRAM area. Depending on the actual SoC a different ARC core is used: - Meson6 and earlier: some ARCv1 ISA based core (probably an ARC625) - Meson8 and later: an ARC EM4 (ARCv2 ISA) based core Add the device-tree node for this remote-processor along with the required SRAM sections, clocks and reset-lines. Also use the SoC-specific compatible string to manage any differences (should they exist). On Meson8, Meson8b and Meson8m2 the "secbus2" IO region is needed as some bits need to be programmed there. Add this IO region for those SoCs as well.

2021-02-03ARM: dts: lpc32xx: Revert set default clock rate of HCLK PLLAlexandre Belloni1-3/+0
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).

Fix the phy-mode description to correctly reflect this so that the implementation doesn't reconfigure the delays incorrectly.
