* remove ioremap_nocache and devm_ioremap_nocacheChristoph Hellwig2020-01-061-1/+1
| | | | | | | | ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Arnd Bergmann <arnd@arndb.de>
* dma-mapping: drop the dev argument to arch_sync_dma_for_*Christoph Hellwig2019-11-201-3/+3
| | | | | | | | These are pure cache maintainance routines, so drop the unused struct device argument. Signed-off-by: Christoph Hellwig <hch@lst.de> Suggested-by: Daniel Vetter <daniel.vetter@ffwll.ch>
* sh: kernel: convert to SPDX identifiersKuninori Morimoto2018-12-281-4/+1
| | | | | | | | | | | | | Update license to use SPDX-License-Identifier instead of verbose license text.

* sh: use generic dma_noncoherent_opsChristoph Hellwig2018-08-021-12/+11

* sh: split arch/sh/mm/consistent.cChristoph Hellwig2018-08-021-0/+84
Half of the file just contains platform device memory setup code which is required for all builds, and half contains helpers for dma coherent allocation, which is only needed if CONFIG_DMA_NONCOHERENT is enabled.
