ARM: pxa: propagate errors from regulator_enable() to pxamci

2013-07-23T19:15:15+00:00

The em_x270_mci_setpower() and em_x270_usb_hub_init() functions
call regulator_enable(), which may return an error that must
be checked.

This changes the em_x270_usb_hub_init() function to bail out
if it fails, and changes the pxamci_platform_data->setpower
callback so that the a failed em_x270_mci_setpower call
can be propagated by the pxamci driver into the mmc core.

mmc: esdhc: Fix bug when writing to SDHCI_HOST_CONTROL register

2013-07-05T16:48:35+00:00

The P2020 has a non-standard implementation of the SDHCI_HOST_CONTROL
register. This patch adds a QUIRK in the SDHCI header to signal that
a host controller has a non-standard SDHCI_HOST_CONTROL register. The
patch adds a check to the function esdhc_writeb in file
sdhci-of-esdhc.c, where it checks if the write is done to the
SDHCI_HOST_CONTROL register and th host has the above mentioned QUIRK,
then the function simply returns instead of writing to the register.
The patch also detects if the processor is P2020 (by looking in dev
tree) and if so, adds the QUIRK to the host->quirk2

mmc: esdhc: Add support for 8-bit bus width and non-removable card

2013-07-05T16:46:30+00:00

This patch adds support of connecting an MMC media using an 8-bit
bus width connection to Freescale's P2020 H/W SDHC controller. During
the probe function, the generic function mmc_of_parse is called to
detect whether the controller is configured with 8-bit bus width.

Also, the generic function detects if the non-removable property is
set in the device tree.  The function esdhc_pltfm_bus_width was added
because the bus width configuration is platform specific.

2013-07-05T16:46:29+00:00

In commit 3451c067 (mmc: omap: add DMA engine support), some #if 0's
were used to comment out parts of the code.  This has been in the code
for over a year and are not needed anymore (and the commented-out code
doesn't even compile).  Remove them.

This patch fixes the HC ctrl_2 programming where, in case of
SDR104 and HS200, we have to write 100b in the the UHS Mode
bits. We wrote 101b that is reserved from Arasan Specs.

mmc: dw_mmc-pltfm: add Rockchip variant

2013-07-05T16:46:27+00:00

Cortex-A9 SoCs from Rockchip use a slightly modified variant of dw_mmc
controllers that seems to require the SDMMC_CMD_USE_HOLD_REG bit to
always be set.

There also seem to be no other modifications (additional register etc)
present, so to keep the footprint low, add this small variant to the
pltfm driver.
