MIPS: alchemy: xxs1500: add gpio-au1000.h header file

2021-05-25T13:16:23+00:00

board-xxs1500.c references 2 functions without declaring them, so add
the header file to placate the build.

../arch/mips/alchemy/board-xxs1500.c: In function 'board_setup':
../arch/mips/alchemy/board-xxs1500.c:56:2: error: implicit declaration of function 'alchemy_gpio1_input_enable' [-Werror=implicit-function-declaration]
   56 |  alchemy_gpio1_input_enable();
../arch/mips/alchemy/board-xxs1500.c:57:2: error: implicit declaration of function 'alchemy_gpio2_enable'; did you mean 'alchemy_uart_enable'? [-Werror=implicit-function-declaration]
   57 |  alchemy_gpio2_enable();

MIPS: Alchemy: Use DEFINE_SPINLOCK() for spinlock

2021-04-12T14:54:57+00:00

spinlock can be initialized automatically with DEFINE_SPINLOCK()
rather than explicitly calling spin_lock_init().

driver core: lift dma_default_coherent into common code

2021-02-13T08:51:45+00:00

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

2021-02-13T08:51:45+00:00

Replace the global coherentio enum, and the hw_coherentio (fake) boolean
variables with a single boolean dma_default_coherent flag.

MIPS/alchemy: factor out the DMA coherent setup

2021-02-13T08:51:45+00:00

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.

MIPS: Remove empty prom_free_prom_memory functions

2021-01-07T16:11:33+00:00

Most of the prom_free_prom_memory functions are empty. With
a new weak prom_free_prom_memory() we can remove all of them.

MIPS: Alchemy: Fix memleak in alchemy_clk_setup_cpu

2020-11-17T11:53:57+00:00

If the clk_register fails, we should free h before
function returns to prevent memleak.

MIPS: replace add_memory_region with memblock

2020-10-12T10:01:36+00:00

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.

MIPS: alchemy: Share prom_init implementation

MIPS: alchemy: Fix build breakage, if TOUCHSCREEN_WM97XX is disabled
