Subject: [PATCH v2 0/7] ARM: shmobile: koelsch reference: Enable DMA for QSPI
Date: Mon, 02 Jun 2014 13:42:04 +0000 [thread overview]
Message-ID: <1401716531-29794-1-git-send-email-geert+renesas@glider.be> (raw)
This patch series enables DMA support for QSPI on r8a7791/koelsch
reference. It's independent from the series "ARM: shmobile: koelsch
legacy: Enable DMA for QSPI", but it depends on the SHDMA work for r8a7790
by Ben Dooks (cfr. "[PATCH v2 0/9] Updates Renesas OF-DMA code").
Changes Compared to previous submission ("[PATCH/RFC 0/7] ARM: shmobile:
r8a7791: Add preliminary DMA support"):
- "[6/7] ARM: shmobile: r8a7791 dtsi: Enable DMA for MSIOF" was dropped,
- 2/7 was added,
- 7/7 was changed (see changelog in individual patch).
This was tested on r8a7791/koelsch.
Performance figures for reading from a QSPI FLASH driven at 24.375 MHz are:
- Single: 1.1 Mbps PIO, 23 Mbps DMA
- Dual : 12.7 Mbps PIO, 48 Mbps DMA
- Quad : 13 Mbps PIO, 70 Mbps DMA
Thanks for your comments!
