Pull ARM SoC updates from Olof Johansson: "A few SoC (code) changes have queued up this cycle, mostly for minor changes and some refactoring and cleanup of legacy platforms. This branch also contains a few of the fixes that weren't sent in by the end of the release (all fairly minor). - Adding an additional maintainer for the TEE subsystem (Sumit Garg) - Quite a significant modernization of the IXP4xx platforms by Linus Walleij, revisiting with a new PCI host driver/binding, removing legacy mach/* include dependencies and moving platform detection/config to drivers/soc. Also some updates/cleanup of platform data. - Core power domain support for Tegra platforms, and some improvements in build test coverage by adding stubs for compile test targets. - A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP support on i.MX7D, SoC ID setup for i.MX50, removal of platform data and board fixups for iMX6/7. ... and a few smaller changes and fixes for Samsung, OMAP, Allwinner, Rockchip" * tag 'arm-soc-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (53 commits) MAINTAINERS: Add myself as TEE subsystem reviewer ixp4xx: fix spelling mistake in Kconfig "Devce" -> "Device" hw_random: ixp4xx: Add OF support hw_random: ixp4xx: Add DT bindings hw_random: ixp4xx: Turn into a module hw_random: ixp4xx: Use SPDX license tag hw_random: ixp4xx: enable compile-testing pata: ixp4xx: split platform data to its own header soc: ixp4xx: move cpu detection to linux/soc/ixp4xx/cpu.h PCI: ixp4xx: Add a new driver for IXP4xx PCI: ixp4xx: Add device tree bindings for IXP4xx ARM/ixp4xx: Make NEED_MACH_IO_H optional ARM/ixp4xx: Move the virtual IObases MAINTAINERS: ARM/MStar/Sigmastar SoCs: Add a link to the MStar tree ARM: debug: add UART early console support for MSTAR SoCs ARM: dts: ux500: Fix LED probing ARM: imx: add smp support for imx7d ARM: imx6q: drop of_platform_default_populate() from init_machine arm64: dts: rockchip: Update RK3399 PCI host bridge window to 32-bit address memory soc/tegra: fuse: Fix Tegra234-only builds ...

pata: ixp4xx: split platform data to its own header

2021-06-17T13:31:04+00:00

Portable drivers cannot use mach/platform.h, so move the structure into its own header. With this, compile testing can be enabled. Signed-off-by: Arnd Bergmann Signed-off-by: Linus Walleij

m68k/q40: Replace q40ide driver with pata_falcon and falconide

2021-06-10T22:30:12+00:00

This allows m68k q40 systems to switch from the deprecated IDE subsystem to libata. Enhance the byte-swapping falconide and pata_falcon platform drivers to accept an irq resource, for use on q40. Atari ST-DMA IRQ arrangements seem to co-exist with q40 IRQ arrangements without too much mess. The new IO resources were added solely for the purpose of making request_region() reservations identical to those made by q40ide: these regions aren't used for actual IO.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

ata: separate PATA timings code from libata-core.c

2020-03-26T16:28:19+00:00

Separate PATA timings code from libata-core.c: * add PATA_TIMINGS config option and make corresponding PATA host drivers (and ATA ACPI code) select it * move following PATA timings code to libata-pata-timings.c: - ata_timing_quantize() - ata_timing_merge() - ata_timing_find_mode() - ata_timing_compute() * group above functions together in * include libata-pata-timings.c in the build when PATA_TIMINGS config option is enabled * cover ata_timing_cycle2mode() with CONFIG_ATA_ACPI ifdef (it depends on code from libata-core.c and libata-pata-timings.c while its only user is ATA ACPI) Code size savings on m68k arch using (modified) atari_defconfig: text data bss dec hex filename before: 39688 573 40 40301 9d6d drivers/ata/libata-core.o after: 37820 572 40 38432 9620 drivers/ata/libata-core.o Reviewed-by: Christoph Hellwig Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Jens Axboe

ata: make SATA_PMP option selectable only if any SATA host driver is enabled

2020-03-26T16:28:17+00:00

There is no reason to expose SATA_PMP config option when no SATA host drivers are enabled. To fix it add SATA_HOST config option, make all SATA host drivers select it and finally make SATA_PMP config options depend on it. This also serves as preparation for the future changes which optimize libata core code size on PATA only setups. CC: "James E.J. Bottomley" Reviewed-by: Martin K.

Add Buddha PATA controller driver. It enables libata support for the Buddha, Catweasel and X-Surf expansion boards on the Zorro expansion bus. Module removal is currently unsupported (the old IDE's buddha driver also doesn't support it).

ata: pata_acpi: Make PCI dependency explicit

2019-01-15T22:16:34+00:00

After commit 5d32a66541c4 (PCI/ACPI: Allow ACPI to be built without CONFIG_PCI set) dependencies on CONFIG_PCI that previously were satisfied implicitly through dependencies on CONFIG_ACPI have to be specified directly. PATA_ACPI is a PCI device driver but the PCI dependency has not been explicitly called out.

ata: remove redundant 'default n' from Kconfig

2018-10-10T20:11:16+00:00

'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ... Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Jens Axboe
