We tested this patch with our current kernel, and have a question
about the addition of the of_rcar_gen2_compatible area.
+static const struct sh_mobile_sdhi_of_data of_rcar_gen2_compatible = {
+ .tmio_flags = TMIO_MMC_HAS_IDLE_WAIT |
TMIO_MMC_WRPROTECT_DISABLE,
+ .capabilities = MMC_CAP_SD_HIGHSPEED | MMC_CAP_SDIO_IRQ,
+ .capabilities2 = MMC_CAP2_NO_MULTI_READ,
+};
We have been doing some speed tests and this is causing an order
of magnitude speed loss with a number of cards. We're seeing
1.2-1.6MB/sec instead of 10+MB/sec we would expect from a Class 10
or UHS-1 card.
Is there any reason to stop using the MULTI_READ as the system seems
to work without MMC_CAP2_NO_MULTI_READ.
Also, this series does not seem to be in any of the git trees I
would expect. Does it need re-sending?
