bcma: lower dependency of BCMA_DRIVER_PCI_HOSTMODE

2015-06-08T11:33:26Z

This extension of BCMA_DRIVER_PCI has no reason to depend on BCMA_HOST_PCI. User may just want to have PCI device attached to SoC registered without enabling any extra client mode code. This can be useful when having non-bcma PCI device attached or when using other PCI driver. Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo

bcma: use absolute base for SoC GPIO pins

2015-05-09T13:28:06Z

On some BCM5301x ARM devices, user space still needs to control some system GPIO pins for which no driver exists. This is a lot easier to do with a predictable GPIO base. Signed-off-by: Felix Fietkau Signed-off-by: Kalle Valo

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2015-04-17T19:50:54Z

Pull MIPS updates from Ralf Baechle: "This is the main pull request for MIPS for Linux 4.1. Most noteworthy: - Add more Octeon-optimized crypto functions - Octeon crypto preemption and locking fixes - Little endian support for Octeon - Use correct CSR to soft reset Octeons - Support LEDs on the Octeon-based DSR-1000N - Fix PCI interrupt mapping for the Octeon-based DSR-1000N - Mark prom_free_prom_memory() as __init for a number of systems - Support for Imagination's Pistachio SOC. This includes arch and CLK bits. I'd like to merge pinctrl bits later - Improve parallelism of csum_partial for certain pipelines - Organize DTB files in subdirs like other architectures - Implement read_sched_clock for all MIPS platforms other than Octeon - Massive series of 38 fixes and cleanups for the FPU emulator / kernel - Further FPU remulator work to support new features. This sits on a separate branch which also has been pulled into the 4.1 KVM branch - Clean up and fixes for the SEAD3 eval board; remove unused file - Various updates for Netlogic platforms - A number of small updates for Loongson 3 platforms - Increase the memory limit for ATH79 platforms to 256MB - A fair number of fixes and updates for BCM47xx platforms - Finish the implementation of XPA support - MIPS FDC support. No, not floppy controller but Fast Debug Channel :) - Detect the R16000 used in SGI legacy platforms - Fix Kconfig dependencies for the SSB bus support" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (265 commits) MIPS: Makefile: Fix MIPS ASE detection code MIPS: asm: elf: Set O32 default FPU flags MIPS: BCM47XX: Fix detecting Microsoft MN-700 & Asus WL500G MIPS: Kconfig: Disable SMP/CPS for 64-bit MIPS: Hibernate: flush TLB entries earlier MIPS: smp-cps: cpu_set FPU mask if FPU present MIPS: lose_fpu(): Disable FPU when MSA enabled MIPS: ralink: add missing symbol for RALINK_ILL_ACC MIPS: ralink: Fix bad config symbol in PCI makefile.

MIPS: BCM47xx: Move NVRAM header to the include/linux/.

2015-04-01T15:22:00Z

There are two reasons for having this header in the common place: 1) Simplifying drivers that read NVRAM entries. We will be able to safely call bcm47xx_nvram_* functions without #ifdef-s. 2) Getting NVRAM driver out of MIPS arch code. This is needed to support BCM5301X arch which also requires this NVRAM driver. Patch for that will follow once we get is reviewed.

bcma: gpio: use predictable base for all BCM47XX buses

2015-03-20T07:08:56Z

Some BCM47XX SoC routers have LEDs connected to extra PCIe bcma buses. Handling them in arch code requires predictable GPIO numbers. Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo

Revert "bcma: Kconfig: Let it depend on PCI"

2015-03-13T14:25:54Z

This reverts commit b09f5ec18b16b82f4db8a735e453332db7514275. Now that we have fully working BCMA_DRIVER_PCI symbol (in can be safely disabled), there is no risk bcma will try to use PCI code without PCI available. Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo

bcma: allow disabling (not building) PCI driver

2015-03-13T14:25:50Z

It isn't required for bcma bus on SoCs, so provide some empty functions and allow disabling it. Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo

bcma: move PCI IRQ control function to host specific code

2015-03-13T14:25:50Z

This function isn't really related to any bus core. It touches PCI device config registers only, so move it to the (PCI) host file. Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo

bcma: prepare Kconfig symbol for PCI driver

2015-03-05T12:11:45Z

Driver for PCIe core requires PCI to be enabled, however we shouldn't require it for the whole bus. Someone may be not interested in extra PCI devices and what's more there are SoCs without any PCI at all (like BCM5356C0, BCM5357*, BCM47186B0). For more details see Kconfig "help". Please note this patch doesn't allow disabling PCI drivers yet, as it requires more work on calls to bcma_core_pci_* functions. Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo
