2022-05-07ARM: pxa/sa1100: move I/O space to PCI_IOBASEArnd Bergmann
PXA and StrongARM1100 traditionally map their I/O space 1:1 into virtual memory, using a per-bus io_offset that matches the base address of the ioremap mapping. In order for PXA to work in a multiplatform config, this needs to change so I/O space starts at PCI_IOBASE (0xfee00000). Since the pcmcia soc_common support is shared with StrongARM1100, both have to change at the same time. The affected machines are: - Anything with a PCMCIA slot now uses pci_remap_iospace, which is made available to PCMCIA configurations as well, rather than just PCI. The first PCMCIA slot now starts at port number 0x10000. - The Zeus and Viper platforms have PC/104-style ISA buses, which have a static mapping for both I/O and memory space at 0xf1000000, which can no longer work. It does not appear to have any in-tree users, so moving it to port number 0 makes them behave like a traditional PC. - SA1100 does support ISA slots in theory, but all machines that originally enabled this appear to have been removed from the tree ages ago, and the I/O space is never mapped anywhere. - The Nanoengine machine has support for PCI slots, but looks like this never included I/O space, the resources only define the location for memory and config space. With this, the definitions of __io() and IO_SPACE_LIMIT can be simplified, as the only remaining cases are the generic PCI_IOBASE and the custom inb()/outb() macros on RiscPC. S3C24xx still has a custom inb()/outb() in this here, but this is already removed in another branch. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2022-05-07ARM: pxa: remove support for MTD_XIPArnd Bergmann
Using MTD-XIP does not work on multiplatform kernels because it requires SoC specific register accesses to be done from low-level flash handling functions in RAM while the rest of the kernel sits in flash. I found no evidence of anyone still actually using this feature, so remove it from PXA to avoid spending a lot of time on actually making it work. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2022-05-07ARM: pxa: move plat-pxa to drivers/soc/Arnd Bergmann
There are two drivers in arch/arm/plat-pxa: mfp and ssp. Both of them should ideally not be needed at all, as there are proper subsystems to replace them. OTOH, they are self-contained and can simply be normal SoC drivers, so move them over there to eliminate one more of the plat-* directories.

2022-05-07ARM: mmp: remove tavorevb board supportArnd Bergmann
There are two tavorevb boards in the kernel, one using a PXA930 chip in mach-pxa, and one using the later PXA910 chip in mach-mmp. They use the same board number, which is generally a bad idea, and in a multiplatform kernel, we can end up with funny link errors like this one resulting from two boards gettting controlled by the same Kconfig symbol: arch/arm/mach-mmp/tavorevb.o: In function `tavorevb_init': tavorevb.c:(.init.text+0x4c): undefined reference to `pxa910_device_uart1' tavorevb.c:(.init.text+0x50): undefined reference to `pxa910_device_gpio' tavorevb.o:(.arch.info.init+0x54): undefined reference to `pxa910_init_irq' tavorevb.o:(.arch.info.init+0x58): undefined reference to `pxa910_timer_init' The mach-pxa TavorEVB seems much more complete than the mach-mmp one that supports only uart, gpio and ethernet. Further, I could find no information about the board on the internet aside from references to the Linux kernel, so I assume this was never available outside of Marvell and can be removed entirely. There is a third board named TavorEVB in the Kconfig description, but this refers to the "TTC_DKB" machine. The two are clearly related, so I change the Kconfig description to just list both names.

The clock register definitions are now used (almost) exclusively in the clk driver, and that relies on no other mach/*.h header files any more. Remove the dependency on mach/pxa*-regs.h by addressing the registers as offsets from a void __iomem * pointer, which is either passed from a board file, or (for the moment) ioremapped at boot time from a hardcoded address in case of DT (this should be moved into the DT of course).

2022-05-07ASoC: pxa: ac97: use normal MMIO accessorsArnd Bergmann
To avoid dereferencing hardwired constant pointers from a global header file, change the driver to use devm_platform_ioremap_resource for getting an __iomem pointer, and then using readl/writel on that. Each pointer dereference gets changed by a search&replace, which leads to a few overlong lines, but seems less risky than trying to clean up the code at the same time.

2022-05-07ARM/pxa/mfd/power/sound: Switch Tosa to GPIO descriptorsLinus Walleij
The Tosa device (Sharp SL-6000) has a mishmash driver set-up for the Toshiba TC6393xb MFD that includes a battery charger and touchscreen and has some kind of relationship to the SoC sound driver for the AC97 codec. Other devices define a chip like this but seem only half-implemented, not really handling battery charging etc. This patch switches the Toshiba MFD device to provide GPIO descriptors to the battery charger and SoC codec. As a result some descriptors need to be moved out of the Tosa boardfile and new one added: all SoC GPIO resources to these drivers now comes from the main boardfile, while the MFD provide GPIOs for its portions. As a result we can request one GPIO from our own GPIO chip and drop two hairy callbacks into the board file. This platform badly needs to have its drivers split up and converted to device tree probing to handle this quite complex relationship in an orderly manner. I just do my best in solving the GPIO descriptor part of the puzzle. Please don't ask me to fix everything that is wrong with these driver to todays standards, I am just trying to fix one aspect. I do try to use modern devres resource management and handle deferred probe using new functions where appropriate.

2022-05-07arm64: kdump: Reimplement crashkernel=XChen Zhou
There are following issues in arm64 kdump: 1. We use crashkernel=X to reserve crashkernel in DMA zone, which will fail when there is not enough low memory. 2. If reserving crashkernel above DMA zone, in this case, crash dump kernel will fail to boot because there is no low memory available for allocation. To solve these issues, introduce crashkernel=X,[high,low]. The "crashkernel=X,high" is used to select a region above DMA zone, and the "crashkernel=Y,low" is used to allocate specified size low memory.

Add fn and fn_arg members into struct kernel_clone_args and test for them in copy_thread (instead of testing for PF_KTHREAD | PF_IO_WORKER). This allows any task that wants to be a user space task that only runs in kernel mode to use this functionality. The code on x86 is an exception and still retains a PF_KTHREAD test because x86 unlikely everything else handles kthreads slightly differently than user space tasks that start with a function. The functions that created tasks that start with a function have been updated to set ".fn" and ".fn_arg" instead of ".stack" and ".stack_size". These functions are fork_idle(), create_io_thread(), kernel_thread(), and user_mode_thread(). Link: https://lkml.kernel.org/r/20220506141512.516114-4-ebiederm@xmission.com Signed-off-by: "Eric W.

2022-05-07ARM: dts: imx6ull-colibri: use pull-down for adc pinsPhilippe Schenker
Disable the keeper and enable a 100k pull-down on the ADC pins as per the following note in section 13.2 of the i.MX 6ULL Application Processor Reference Manual, Rev. 1, 11/2017 [1]: The keeper causes an undesired jump behavior in ADC. To avoid the problem, disable keeper before starting ADC.
