Subject: [PATCH v3 0/2] Chunk splitting of spi transfers
Date: Mon, 12 Mar 2018 09:53:30 +0000 [thread overview]
Message-ID: <cover.1520848302.git.meghana.madhyastha@gmail.com> (raw)
-Call spi_split_transfers_maxsize in __spi_pump_messages
to split large chunks for spi dma transfers.
-Remove chunk splitting in the tinydrm spi helper (as now the core is
handling the chunk splitting).
Changes in v3:
-Remove max_chunk
-Remove tinydrm_spi_max_transfer_size()
-Change master->max_dma_len in patch 0/2 and explain why it is changed
