mmc: omap_hsmmc: Skip platform_get_resource_byname() for dt case

2013-05-26T18:23:11+00:00

MMC driver probe will abort for DT case because of failed
platform_get_resource_byname() lookup. Fix it by skipping resource
lookup byname for device tree build.

Issue is hidden because hwmod populates the IO resources which
helps to succeed platform_get_resource_byname() and probe.

mmc: omap_hsmmc: convert to dma_request_slave_channel_compat

2013-05-26T18:23:10+00:00

Convert dmaengine channel requests to use
dma_request_slave_channel_compat(). This supports platforms booting
with or without DT populated.

mmc: omap_hsmmc: Fix the DT pbias workaround for MMC controllers 2 to 5

2013-05-26T18:23:09+00:00

Otherwise SDIO cards won't necessarily work when booted with
device tree as we will never power down the SDIO cards. This
means the SDIO card reset does not happen which at least some
WLAN controllers expect to happen with ifconfig wlan0 down.

The PBIAS voltage is only available for the first controller
instance, so let's limit the PBIAS workaround to the first
controller only.

mmc: sdhci-acpi: add more device ids

2013-05-26T17:50:50+00:00

Add three more ACPI HIDs.  Also, as some devices must be
further distinguished by ACPI UID, slot information is now
associated with HID and UID.

mmc: sdhci-esdhc-imx: fix multiblock reads on i.MX53

2013-05-26T17:13:31+00:00

The eSDHC controller on the i.MX53 needs an additional, non spec
compliant CMD12 after a multiblock read with a predefined number of
blocks. Otherwise the internal state machine won't go back to the
idle state.

This commit effectively reverts 5b6b0ad6 (mmc: sdhci-esdhc-imx:
fix for mmc cards on i.MX5), which fixed part of the problem by
making multiblock reads work, however this fix was not sufficient
when multi- and singleblock reads got intermixed.

This implements the recommended workaround (Freescale i.MX Reference
Manual, section 29.6.8 "Multi-block Read") by manually sending a
CMD12 with the RSPTYP bits cleared.

mmc: sdhci-esdhc-imx: Fix SDIO interrupts

2013-05-26T17:10:36+00:00

Currently SDIO interrupts do not work on i.MX53 and maybe others.

This was observed with a Marvell 8787 based SDIO wifi adapter
using the mwifiex driver and firmware from the Marvell git
repository.
The symptom was a timeout after firmware download.

Observing the SDIO_DAT1 line showed that an interrupt was requested
(level 0) but no interrupt was generated in software, the line
stayed low until a timeout ocurred and the card was reset.

There is a Freescale errata
	ENGcm11186 "eSDHC misses SDIO interrupt when CINT is disabled"

The workaround suggested by this errata is already implemented and
involves clearing and then setting the D3CD bit in the host control
register [see esdhc_writel_le()]

However, when esdhc_writeb_le() is later used to write to
SDHCI_HOST_CONTROL it always resets the D3CD bit.

To fix this simply add the D3CD bit to the set of bits
not modified by esdhc_writeb_le().
