MIPS: alchemy: Fix build error after ioremap cleanup

2020-04-20T11:31:38+00:00

IOremap changes caused following build error: arch/mips/alchemy/common/setup.c:99:9: error: implicit declaration of function +‘remap_pfn_range’; did you mean ‘io_remap_pfn_range’? +[-Werror=implicit-function-declaration] Fixed my including linux/mm.h Fixes: d399157283fb ("MIPS: cleanup fixup_bigphys_addr handling") Signed-off-by: Thomas Bogendoerfer

MIPS: cleanup fixup_bigphys_addr handling

2020-04-19T14:09:44+00:00

fixup_bigphys_addr is only provided by the alchemy platform. Remove all the stubs, and ensure we only call it if it is actually implemented. Also don't bother implementing io_remap_pfn_range if we don't have to, and move the remaining implementation to alchemy platform code.

MIPS: Sanitise coherentio semantics

2016-10-06T16:01:28+00:00

The coherentio variable has previously been used as a boolean value, indicating whether the user specified that coherent I/O should be enabled or disabled. It failed to take into account the case where the user does not specify any preference, in which case it makes sense that we should default to coherent I/O if the hardware supports it (hw_coherentio is non-zero). Introduce an enum to clarify the 3 different values of coherentio & use it throughout the code, modifying plat_device_is_coherent() & r4k_cache_init() to take into account the default case.

MIPS: Alchemy: remove declaration for set_cpuspec

2015-02-20T12:00:45+00:00

set_cpuspec() has been dropped with commit 074cf656700ddd1d2bd7f815f78e785418beb898 ("MIPS: Alchemy: remove cpu_table.") in late 2008. Signed-off-by: Manuel Lauss Cc: Linux-MIPS Patchwork: https://patchwork.linux-mips.org/patch/9150/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: remove old clock support

With the clock framework in place, remove unused functions and bits, and drop the CLK_IGNORE_UNUSED flag, which is now unneeded. Signed-off-by: Manuel Lauss Cc: Linux-MIPS Patchwork: https://patchwork.linux-mips.org/patch/7473/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: Default to noncoherent IO on Au1200 AB

CONFIG_DMA_COHERENT is no longer set; default to noncoherent io on Au1200 revision AB to make USB work. Signed-off-by: Manuel Lauss Cc: Linux-MIPS Patchwork: https://patchwork.linux-mips.org/patch/6745/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: Determine cohereny at runtime based on cpu type

2014-03-26T22:09:21+00:00

All Alchemy chips have coherent DMA, but for example the USB or AC97 peripherals on the Au1000/1500/1100 are not. This patch uses DMA_MAYBE_COHERENT on Alchemy and sets coherentio based on CPU type.
