MIPS: Alchemy: Use DEFINE_SPINLOCK() for spinlock

2021-04-12T14:54:57Z

spinlock can be initialized automatically with DEFINE_SPINLOCK() rather than explicitly calling spin_lock_init(). Reported-by: Hulk Robot Signed-off-by: Lifu Chen Signed-off-by: Thomas Bogendoerfer

driver core: lift dma_default_coherent into common code

2021-02-13T08:51:45Z

Lift the dma_default_coherent variable from the mips architecture code to the driver core. This allows an architecture to sdefault all device to be DMA coherent at run time, even if the kernel is build with support for DMA noncoherent device. By allowing device_initialize to set the ->dma_coherent field to this default the amount of arch hooks required for this behavior can be greatly reduced.

MIPS: refactor the runtime coherent vs noncoherent DMA indicators

2021-02-13T08:51:45Z

Replace the global coherentio enum, and the hw_coherentio (fake) boolean variables with a single boolean dma_default_coherent flag. Signed-off-by: Christoph Hellwig Signed-off-by: Thomas Bogendoerfer

MIPS/alchemy: factor out the DMA coherent setup

2021-02-13T08:51:45Z

Factor out a alchemy_dma_coherent helper that determines if the platform is DMA coherent. Also stop initializing the hw_coherentio variable, given that is only ever set to a non-zero value by the malta setup code. Signed-off-by: Christoph Hellwig Signed-off-by: Thomas Bogendoerfer

MIPS: Remove empty prom_free_prom_memory functions

2021-01-07T16:11:33Z

Most of the prom_free_prom_memory functions are empty. With a new weak prom_free_prom_memory() we can remove all of them. Signed-off-by: Thomas Bogendoerfer Acked-by: Florian Fainelli

MIPS: Alchemy: Fix memleak in alchemy_clk_setup_cpu

2020-11-17T11:53:57Z

If the clk_register fails, we should free h before function returns to prevent memleak. Fixes: 474402291a0ad ("MIPS: Alchemy: clock framework integration of onchip clocks") Reported-by: Hulk Robot Signed-off-by: Zhang Qilong Signed-off-by: Thomas Bogendoerfer

MIPS: replace add_memory_region with memblock

2020-10-12T10:01:36Z

add_memory_region was the old interface for registering memory and was already changed to used memblock internaly. Replace it by directly calling memblock functions. Signed-off-by: Thomas Bogendoerfer

MIPS: alchemy: Share prom_init implementation

2020-10-06T10:33:57Z

All boards have the same prom_init() function. Move it to common code and delete the duplicates. Signed-off-by: Thomas Bogendoerfer

MIPS: alchemy: Fix build error after ioremap cleanup

2020-04-20T11:31:38Z

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

2020-04-19T14:09:44Z

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.
