mmc: renesas_sdhi_internal_dmac: set scatter/gather max segment size
Fix warning when running with CONFIG_DMA_API_DEBUG_SG=y by allocating a device_dma_parameters structure and filling in the max segment size. The size used is the result of a discussion with Renesas hardware engineers and unfortunately not found in the datasheet. renesas_sdhi_internal_dmac ee140000.sd: DMA-API: mapping sg segment longer than device claims to support [len=126976] [max=65536] Reported-by: NGeert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: NNiklas Söderlund <niklas.soderlund+renesas@ragnatech.se> [wsa: simplified some logic after validating intended dma_parms life cycle and added comment] Signed-off-by: NWolfram Sang <wsa+renesas@sang-engineering.com> Signed-off-by: NUlf Hansson <ulf.hansson@linaro.org>
