| 2024-12-02 | dmaengine: loongson2-apb: Change GENMASK to GENMASK_ULL | Binbin Zhou | |
| Fix the following smatch static checker warning: drivers/dma/loongson2-apb-dma.c:189 ls2x_dma_write_cmd() warn: was expecting a 64 bit value instead of '~(((0)) + (((~((0))) - (((1)) << (0)) + 1) & (~((0)) >> ((8 * 4) - 1 - (4)))))' The GENMASK macro used "unsigned long", which caused build issues when using a 32-bit toolchain because it would try to access bits > 31. This patch switches GENMASK to GENMASK_ULL, which uses "unsigned long long". Fixes: 71e7d3cb6e55 ("dmaengine: ls2x-apb: New driver for the Loongson LS2X APB DMA controller") Reported-by: Dan Carpenter <dan.carpenter@linaro.org> Closes: https://lore.kernel.org/all/87cdc025-7246-4548-85ca-3d36fdc2be2d@stanley.mountain/ Signed-off-by: Binbin Zhou <zhoubinbin@loongson.cn> Link: https://lore.kernel.org/r/20241028093413.1145820-1-zhoubinbin@loongson.cn Signed-off-by: Vinod Koul <vkoul@kernel.org> | |||
| 2024-10-23 | dmaengine: loongson2-apb: Rename the prefix ls2x to loongson2 | Binbin Zhou | |
| Since commit e06c43231214 ("dmaengine: Loongson1: Add Loongson-1 APB DMA driver"), the Loongson-1 dma controller was added. Unfortunately their naming has not been standardized, as CPUs belonging to the same Loongson family, we expect to standardize the naming for ease of understanding.
