2020-01-06remove ioremap_nocache and devm_ioremap_nocacheChristoph Hellwig
ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Arnd Bergmann <arnd@arndb.de>
2018-08-09ssb: Remove SSB_WARN_ON, SSB_BUG_ON and SSB_DEBUGMichael Büsch
Use the standard WARN_ON instead. If a small kernel is desired, WARN_ON can be disabled globally. Also remove SSB_DEBUG. Besides WARN_ON it only adds a tiny debug check. Include this check unconditionally. Signed-off-by: Michael Buesch <m@bues.ch> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-08-09ssb: Remove home-grown printk wrappersMichael Büsch
Replace the ssb printk wrappers by standard print helpers. Also remove SSB_SILENT. Nobody should use it anyway. Originally submitted by Joe Perches <joe@perches.com>.

2013-01-03Drivers: ssb: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-02-01ssb: fix cardbus slot in hostmodeHauke Mehrtens

2011-12-08ssb: fix init regression with SoCsHauke Mehrtens
This fixes a Data bus error on some SoCs. The first fix for this problem did not solve it on all devices. commit 6ae8ec27868bfdbb815287bee8146acbefaee867 Author: Rafał Miłecki <zajec5@gmail.com> Date: Tue Jul 5 17:25:32 2011 +0200 ssb: fix init regression of hostmode PCI core In ssb_pcicore_fix_sprom_core_index() the sprom on the PCI core is accessed, but the sprom only exists when the ssb bus is connected over a PCI bus to the rest of the system and not when the SSB Bus is the main system bus. SoCs sometimes have a PCI host controller and there this code will not be executed, but there are some old SoCs with an PCI controller in client mode around and ssb_pcicore_fix_sprom_core_index() should not be called on these devices too. The PCI controller on these devices are unused, but without this fix it results in an Data bus error when it gets initialized.

2011-06-22ssb: add __devinit to some functionsHauke Mehrtens
Two functions in ssb are using register_pci_controller() which is __devinit. The functions ssb_pcicore_init_hostmode() and ssb_gige_probe() should also be __devinit. This fixes the following warning: WARNING: vmlinux.o(.text+0x2727b8): Section mismatch in reference from the function ssb_pcicore_init_hostmode() to the function .devinit.text:register_pci_controller() The function ssb_pcicore_init_hostmode() references the function __devinit register_pci_controller(). This is often because ssb_pcicore_init_hostmode lacks a __devinit annotation or the annotation of register_pci_controller is wrong. WARNING: vmlinux.o(.text+0x273398): Section mismatch in reference from the function ssb_gige_probe() to the function .devinit.text:register_pci_controller() The function ssb_gige_probe() references the function __devinit register_pci_controller().

2010-04-12MIPS: Fix SSB PCIcore IO resource managementAndreas Ferber
The SSB PCIcore code reused the IO resource fixup code from the original 2.4.x Broadcom patch for BCM47xx based devices, which was a quick hack for doing PCI IO resource configuration back then (the boot loader doesn't configure PCI devices on this platform). However, this code is no longer necessary since the kernel now can do PCI resource management fine all by itself, so remove the old code. When removing the code, it becomes obvious that the mem_offset setting in the PCIcore driver was wrong, however this was masked by the fixup code before, except in a few cases involving yenta_socket. For BCM47xx, the correct offset is 0, and since this is the only device using PCIcore in host mode, the offset can simply be removed unconditionally.
