gpiolib: split of_mm_gpio_chip out of linux/of_gpio.h

2023-03-06T10:33:01+00:00

This is a rarely used feature that has nothing to do with the client-side of_gpio.h. Split it out with a separate header file and Kconfig option so it can be removed on its own timeline aside from removing the of_gpio consumer interfaces.

powerpc/akebono: Fix unmet dependency errors

2021-02-08T13:10:50+00:00

The AKEBONO config has various selects under it, including some with user-selectable dependencies, which means those dependencies can be disabled. This leads to warnings from Kconfig. This can be seen with eg: $ make allnoconfig $ ./scripts/config --file build~/.config -k -e CONFIG_44x -k -e CONFIG_PPC_47x -e CONFIG_AKEBONO $ make olddefconfig WARNING: unmet direct dependencies detected for ATA Depends on [n]: HAS_IOMEM [=y] && BLOCK [=n] Selected by [y]: - AKEBONO [=y] && PPC_47x [=y] WARNING: unmet direct dependencies detected for NETDEVICES Depends on [n]: NET [=n] Selected by [y]: - AKEBONO [=y] && PPC_47x [=y] WARNING: unmet direct dependencies detected for ETHERNET Depends on [n]: NETDEVICES [=y] && NET [=n] Selected by [y]: - AKEBONO [=y] && PPC_47x [=y] WARNING: unmet direct dependencies detected for MMC_SDHCI Depends on [n]: MMC [=n] && HAS_DMA [=y] Selected by [y]: - AKEBONO [=y] && PPC_47x [=y] WARNING: unmet direct dependencies detected for MMC_SDHCI_PLTFM Depends on [n]: MMC [=n] && MMC_SDHCI [=y] Selected by [y]: - AKEBONO [=y] && PPC_47x [=y] The problem is that AKEBONO is using select to enable things that are not true dependencies, but rather things you probably want enabled in an AKEBONO kernel. That is what a defconfig is for. So drop those selects and instead move those symbols into the defconfig. This fixes all the kconfig warnings, and the result of make 44x/akebono_defconfig is the same before and after the patch.

powerpc: Remove Xilinx PPC405/PPC440 support

2020-05-28T13:24:34+00:00

The latest Xilinx design tools called ISE and EDK has been released in October 2013. New tool doesn't support any PPC405/PPC440 new designs. These platforms are no longer supported and tested. PowerPC 405/440 port is orphan from 2013 by commit cdeb89943bfc ("MAINTAINERS: Fix incorrect status tag") and commit 19624236cce1 ("MAINTAINERS: Update Grant's email address and maintainership") that's why it is time to remove the support fot these platforms.

powerpc/44x: Force PCI on for CURRITUCK

2019-02-21T13:10:15+00:00

The recent rework of PCI kconfig symbols exposed an existing bug in the CURRITUCK kconfig logic. It selects PPC4xx_PCI_EXPRESS which depends on PCI, but PCI is user selectable and might be disabled, leading to a warning: WARNING: unmet direct dependencies detected for PPC4xx_PCI_EXPRESS Depends on [n]: PCI [=n] && 4xx [=y] Selected by [y]: - CURRITUCK [=y] && PPC_47x [=y] Prior to commit eb01d42a7778 ("PCI: consolidate PCI config entry in drivers/pci") PCI was enabled by default for currituck_defconfig so we didn't see the warning. The bad logic was still there, it just required someone disabling PCI in their .config to hit it. Fix it by forcing PCI on for CURRITUCK, which seems was always the expectation anyway.

PCI: consolidate PCI config entry in drivers/pci

2018-11-23T02:45:34+00:00

There is no good reason to duplicate the PCI menu in every architecture. Instead provide a selectable HAVE_PCI symbol that indicates availability of PCI support, and a FORCE_PCI symbol to for PCI on and the handle the rest in drivers/pci.
