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

2015-06-07T13:28:57+00:00

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.

mn10300: add io{read,write}{16,32}be functions

2015-04-23T03:37:56+00:00

These functions are used in various drivers, including the latest version of the 8250 driver. The latter causes the following build failure. drivers/tty/serial/8250/8250_core.c: In function 'mem32be_serial_out': drivers/tty/serial/8250/8250_core.c:456:2: error: implicit declaration of function 'iowrite32be' drivers/tty/serial/8250/8250_core.c: In function 'mem32be_serial_in': drivers/tty/serial/8250/8250_core.c:462:2: error: implicit declaration of function 'ioread32be' Cc: Kevin Cernekee Acked-by: Greg Kroah-Hartman Fixes: c627f2ceb692 ("serial: 8250: Add support for big-endian MMIO accesses") Signed-off-by: Guenter Roeck Signed-off-by: Rob Herring

mn10300: io: implement dummy relaxed accessor macros for writes

2014-10-20T17:49:18+00:00

write{b,w,l}_relaxed are implemented by some architectures in order to permit memory-mapped I/O accesses with weaker barrier semantics than the non-relaxed variants. This patch adds dummy macros for the write accessors to mn10300, in the same vein as the dummy definitions for the relaxed read accessors. Cc: David Howells Signed-off-by: Will Deacon

MN10300: Use asm-generic/pci_iomap.h

2012-12-12T15:46:15+00:00

The declarations from MN10300's pci_iomap() was removed by commit 34f1bdee1910f7efe3c32e1a891dba4fd21cb3b6 but asm-generic/pci_iomap.h wasn't then #included from asm/io.h. Signed-off-by: David Howells

MN10300: Handle cacheable PCI regions in pci_iomap()

2012-12-12T15:46:14+00:00

Handle cacheable PCI regions in pci_iomap(). If IORESOURCE_CACHEABLE is set then we AND away the 0x20000000 "flag". Signed-off-by: David Howells

mn10300: switch to GENERIC_PCI_IOMAP

2011-12-04T14:00:17+00:00

The pci_iomap variant that arch/mn10300/unit-asb2305/pci-iomap.c uses differs from the generic one in that it does not use ioremap_nocache for PCI addresses. However, it turns out that PCI addresses are automatically noncached, so switching to ioremap_nocache and to the generic implementation is safe. Signed-off-by: Michael S. Tsirkin

mn10300: add missing __iomap markers
