bcma: lower dependency of BCMA_DRIVER_PCI_HOSTMODE

2015-06-08T11:33:26+00:00

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.

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

2015-03-13T14:25:54+00:00

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.

bcma: allow disabling (not building) PCI driver

2015-03-13T14:25:50+00:00

It isn't required for bcma bus on SoCs, so provide some empty functions
and allow disabling it.

bcma: prepare Kconfig symbol for PCI driver

2015-03-05T12:11:45+00:00

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.

bcma: Kconfig: Let it depend on PCI

2015-03-05T11:56:59+00:00

bcma also needs PCI, just like IOMEM and DMA, so let it depend on PCI,
or will cause building break for allmodconfig under c6x:

bcma: gpio: add own IRQ domain

2014-01-23T12:02:37+00:00

Input GPIO changes can generate interrupts, but we need kind of ACK for
them by changing IRQ polarity. This is required to stop hardware from
keep generating interrupts and generate another one on the next GPIO
state change.
This code allows using GPIOs with standard interrupts and add for
example GPIO buttons support.

bcma: BCMA_DRIVER_GPIO should depend on GPIOLIB instead of selecting it

2013-01-02T19:38:22+00:00

Commit cf0936b06d8e98a157630e99f647e2ff6d29d7ad ("bcma: add GPIO driver")
added BCMA_DRIVER_GPIO, which unconditionally selects GPIOLIB, causing
a Kconfig warning:

warning: (ARCH_REQUIRE_GPIOLIB && SSB_DRIVER_GPIO && BCMA_DRIVER_GPIO && MFD_TC6393XB && FB_VIA) selects GPIOLIB which has unmet direct dependencies (ARCH_WANT_OPTIONAL_GPIOLIB || ARCH_REQUIRE_GPIOLIB)

and build failure for m68k/allmodconfig:

bcma: add GPIO driver

2012-11-21T20:55:52+00:00

Register a GPIO driver to access the GPIOs provided by the chip.
The GPIOs of the SoC should always start at 0 and the other GPIOs could
start at a random position. There is just one SoC in a system and when
they start at 0 the number is predictable.
