[ Upstream commit 3c1e5abcda64bed0c7bffa65af2316995f269a61 ] When calling spi_register_board_info(), Fixes: f869d42e580f ("MIPS: Alchemy: Improved DB1550 support, with audio and serial busses.") Signed-off-by: Christophe JAILLET Signed-off-by: Thomas Bogendoerfer Signed-off-by: Sasha Levin

MIPS: Alchemy: Fix an out-of-bound access in db1200_dev_setup()

2024-01-25T22:52:50+00:00

[ Upstream commit 89c4b588d11e9acf01d604de4b0c715884f59213 ] When calling spi_register_board_info(), we should pass the number of elements in 'db1200_spi_devs', not 'db1200_i2c_devs'.

MIPS: Alchemy: only build mmc support helpers if au1xmmc is enabled

2023-10-06T11:18:12+00:00

[ Upstream commit ef8f8f04a0b25e8f294b24350e8463a8d6a9ba0b ] While commit d4a5c59a955b ("mmc: au1xmmc: force non-modular build and remove symbol_get usage") to be built in, it can still build a kernel without MMC support and thuse no mmc_detect_change symbol at all. Add ifdefs to build the mmc support code in the alchemy arch code conditional on mmc support.

mmc: au1xmmc: force non-modular build and remove symbol_get usage

2023-09-06T20:28:37+00:00

commit d4a5c59a955bba96b273ec1a5885bada24c56979 upstream. au1xmmc is split somewhat awkwardly into the main mmc subsystem driver, and callbacks in platform_data that sit under arch/mips/ and are always built in. The latter than call mmc_detect_change through symbol_get. Remove the use of symbol_get by requiring the driver to be built in. In the future the interrupt handlers for card insert/eject detection should probably be moved into the main driver, and which point it can be built modular again.

MIPS: Alchemy: fix dbdma2

2023-06-21T13:59:13+00:00

[ Upstream commit 2d645604f69f3a772d58ead702f9a8e84ab2b342 ] Various fixes for the Au1200/Au1550/Au1300 DBDMA2 code: - skip cache invalidation if chip has working coherency circuitry. - invalidate KSEG0-portion of the (physical) data address. - force the dma channel doorbell write out to bus immediately with a sync.

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.
