2016-03-07bcma: move parallel flash support to separated fileRafał Miłecki
This follows the way of handling other flashes and cleans code a bit. As next task we will want to move flash code to ChipCommon driver as: 1) Flash controllers are accesible using ChipCommon registers 2) This code isn't MIPS specific This change prepares bcma for that.

2015-08-18bcma: switch GPIO portions to use GPIOLIB_IRQCHIPLinus Walleij
This switches the BCMA GPIO driver to use GPIOLIB_IRQCHIP to handle its interrupts instead of rolling its own copy of the irqdomain handling etc. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-06-08bcma: lower dependency of BCMA_DRIVER_PCI_HOSTMODERafał Miłecki
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 <zajec5@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-03-13Revert "bcma: Kconfig: Let it depend on PCI"Rafał Miłecki
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.

2015-03-13bcma: allow disabling (not building) PCI driverRafał Miłecki
It isn't required for bcma bus on SoCs, so provide some empty functions and allow disabling it. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-03-05bcma: prepare Kconfig symbol for PCI driverRafał Miłecki
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.

2014-01-23bcma: gpio: add own IRQ domainRafał Miłecki
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.

2013-01-02bcma: BCMA_DRIVER_GPIO should depend on GPIOLIB instead of selecting itGeert Uytterhoeven
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: In file included from include/linux/bcma/bcma.h:8, from drivers/bcma/bcma_private.h:9, from drivers/bcma/main.c:9: include/linux/bcma/bcma_driver_chipcommon.h:582: error: field ‘gpio’ has incomplete type In file included from include/linux/bcma/bcma.h:12, from drivers/bcma/bcma_private.h:9, from drivers/bcma/main.c:9: include/linux/ssb/ssb.h:440: error: field ‘gpio’ has incomplete type make[4]: *** [drivers/bcma/main.o] Error 1 make[3]: *** [drivers/bcma/] Error 2 Turn the select into a dependency to fix this.

2012-11-21bcma: add GPIO driverHauke Mehrtens
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.

2012-04-10bcma: fix build error on MIPS; implicit pcibios_enable_devicePaul Gortmaker
The following is seen during allmodconfig builds for MIPS: drivers/bcma/driver_pci_host.c:518:2: error: implicit declaration of function 'pcibios_enable_device' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[3]: *** [drivers/bcma/driver_pci_host.o] Error 1 Most likey introduced by commit 49dc9577155576b10ff79f0c1486c816b01f58bf "bcma: add PCIe host controller" Add the header instead of implicitly assuming it will be present. Sounds like a good idea, but that alone doesn't fix anything. The real problem is that the Kconfig has settings related to whether PCI is possible, i.e. config BCMA_HOST_PCI_POSSIBLE bool depends on BCMA && PCI = y default y config BCMA_HOST_PCI bool "Support for BCMA on PCI-host bus" depends on BCMA_HOST_PCI_POSSIBLE ...but what is missing is that BCMA_DRIVER_PCI_HOSTMODE doesn't have any dependencies on the above.

2011-08-08bcma: add SOC busHauke Mehrtens
This patch adds support for using bcma on a Broadcom SoC as the system bus. An SoC like the bcm4716 could register this bus and use it to searches for the bcma cores and register the devices on this bus. BCMA_HOSTTYPE_NONE was intended for SoCs at first but BCMA_HOSTTYPE_SOC is a better name.

2011-05-10bcma: add Broadcom specific AMBA bus driverRafał Miłecki
Broadcom has released cards based on a new AMBA-based bus type. From a programming point of view, this new bus type differs from AMBA and does not use AMBA common registers. It also differs enough from SSB. We decided that a new bus driver is needed to keep the code clean. In its current form, the driver detects devices present on the bus and registers them in the system. It allows registering BCMA drivers for specified bus devices and provides them basic operations. The bus driver itself includes two important bus managing drivers: ChipCommon core driver and PCI(c) core driver. They are early used to allow correct initialization. Currently code is limited to supporting buses on PCI(e) devices, however the driver is designed to be used also on other hosts. The host abstraction layer is implemented and already used for PCI(e). Support for PCI(e) hosts is working and seems to be stable (access to 80211 core was tested successfully on a few devices). We can still optimize it by using some fixed windows, but this can be done later without affecting any external code. Windows are just ranges in MMIO used for accessing cores on the bus.
