Subject: [PATCH v2 0/2] Chunk splitting of spi transfers
Date: Sat, 10 Mar 2018 15:50:48 +0000 [thread overview]
Message-ID: <cover.1520691344.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 v2:
-Change the order of the two patches in the patchset.
-Undo the spurious blank line deletions
-Remove bcm2835_spi_transfer_one_message and add spi_split_transfers_maxsize
in __spi_pump_messages. This solves the DMA time out error.
