exynos: more debug and cleanup in do_sdhci_init()

2015-10-13T11:22:28Z

Add more debug printfs in do_sdhci_init() for calls that can potentially fail. Acked-by: Przemyslaw Marczak Signed-off-by: Tobias Jakobi Signed-off-by: Minkyu Kang

exynos: be more verbose in process_nodes()

2015-10-13T11:22:28Z

In case sdhci_get_config() or do_sdhci_init() fail, show the error code that was returned. Acked-by: Przemyslaw Marczak Signed-off-by: Tobias Jakobi Signed-off-by: Minkyu Kang

exynos: Fix passing of errors in exynos_mmc_init()

2015-10-13T11:22:28Z

exynos_mmc_init() always returns zero, so for the caller it looks like it never fails. Correct this by returning the error code of process_nodes(). For process_nodes() do something similar and return early when do_sdhci_init() fails. v2: Only fail in process_nodes() if we fail on all available nodes.

exynos: Properly zero initialize host in s5p_sdhci_init()

2015-10-13T11:22:28Z

This makes sure that setting the host_caps in s5p_sdhci_core_init() doesn't operate on potentially uninitialized memory. Acked-by: Lukasz Majewski Signed-off-by: Tobias Jakobi Signed-off-by: Minkyu Kang

sunxi: mmc: Fix clk-delay settings

2015-09-29T09:50:07Z

In recent allwinner kernel sources the mmc/sdio clk-delay settings have been slightly tweaked, and for sun9i they are completely different then what we are using. This commit brings us in sync with what allwinner does, fixing problems accessing sdcards on some A33 devices (and likely others). For pre sun9i hardware this makes the following changes: -At 400Khz change the sample delay from 7 to 0 (first introduced in A31 sdk) -At 50 Mhz change the sample delay from 5 to 4 (first introduced in A23 sdk) -Above 50 MHz change the out delay from 2 to 1 (first introduced in A20 sdk) Signed-off-by: Hans de Goede Acked-by: Ian Campbell

mmc: dw_mmc: Increase timeout to 4 minutes (as in Linux kernel)

2015-09-28T15:03:56Z

The commit: d9dbb97be0e4a550457aec5f11afefb446169c90 "mmc: dw_mmc: Zap endless timeout" removed endless loop waiting for end of dw mmc transfer. For some workloads - dfu test @ Odroid XU3 (sending 8MiB file) - and SD cards (e.g. MicroSD Kingston 4GiB, Adata 4GiB) the default timeout is to short. The new value - 4 minutes (240 seconds) - is the same as the one used in Linux kernel driver. Such fix should be good enough until we come up with better fix for this issue.

Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h header

2015-09-11T21:15:20Z

Now that we have a new header file for cache-aligned allocation, we should move the stack-based allocation macro there also. Signed-off-by: Simon Glass

mmc: dw_mmc: Probe the MMC from OF

2015-09-04T09:54:20Z

Rework the driver to probe the MMC controller from Device Tree and make it mandatory. There is no longer support for probing from the ancient qts-generated header files. This patch now also removes previous temporary workaround. Signed-off-by: Marek Vasut Cc: Dinh Nguyen Cc: Pantelis Antoniou Cc: Tom Rini

rockchip: Add an MMC driver

2015-09-03T03:28:24Z

Add an MMC driver which supports RK3288, but may also support other SoCs. It uses the Designware MMC device. Signed-off-by: Simon Glass
