microblaze: fix iounmap prototype

2018-01-17T12:34:35Z

The missing 'volatile' keyword on the iounmap argument leads to lots of harmless warnings in an allmodconfig build: sound/pci/echoaudio/echoaudio.c:1879:10: warning: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type [-Wdiscarded-qualifiers] Signed-off-by: Arnd Bergmann Signed-off-by: Michal Simek

video/fbdev, asm/io.h: Remove ioremap_writethrough()

2015-06-07T13:28:57Z

Replace all calls to ioremap_writethrough() with ioremap_wt(). Remove ioremap_writethrough() too.

arch/*/io.h: Add ioremap_wt() to all architectures

2015-06-07T13:28:57Z

Add ioremap_wt() to all arch-specific asm/io.h headers which define ioremap_wc() locally. These headers do not include . Some of them include , but ioremap_wt() is defined for consistency since they define all ioremap_xxx locally. In all architectures without Write-Through support, ioremap_wt() is defined indentical to ioremap_nocache(). frv and m68k already have ioremap_writethrough(). On those we add ioremap_wt() indetical to ioremap_writethrough() and defines ARCH_HAS_IOREMAP_WT in both architectures. The ioremap_wt() interface is exported to drivers.

microblaze: io: remove dummy relaxed accessor macros

2014-10-20T17:49:17Z

These are now defined by asm-generic/io.h, so we don't need the private definitions anymore. Acked-by: Michal Simek Signed-off-by: Will Deacon

microblaze: Cleanup PCI_DRAM_OFFSET handling

2014-06-04T04:59:57Z

PCI_DRAM_OFFSET/pci_dram_offset is 0 all the time and there is no difference for PCI and !PCI cases. Also remove the whole code which setup archdata.dma_data which is completely unused. Signed-off-by: Michal Simek

microblaze: Use asm-generic/io.h

2014-04-07T12:25:53Z

Using generic io.h will narrow down code duplication in architecture io.h. - define PCI_IOBASE - remove non existing pci_io_base extern Signed-off-by: Michal Simek

microblaze: Define readq and writeq IO helper function

2014-02-10T06:42:03Z

Some drivers check if readq/writeq functions are defined. If not internal driver functions are used which cause compilation failures. Signed-off-by: Michal Simek

microblaze: Define read/write{b,w,l}_relaxed MMIO

2014-01-27T10:26:32Z

More and more ARM specific drivers is using MMIO readX/writeX_relaxed IO functions and Microblaze can shared some drivers with ARM too. This patch adds relaxed IO accessor macros to prevent compilation failures. Signed-off-by: Michal Simek

microblaze: Use proper casting for inb/inw/inl in io.h

2013-05-23T06:49:33Z

We are going to move to asm-generic/io.h but let's fix compilation warnings first for 3.10. Warning message: arch/microblaze/include/asm/io.h:126:26: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] #define inb(port) readb((u8 *)((port))) ...
