2013-09-11	e3ab307 Browse files » MCI: imx-esdhc: implement workaround for errata ENGcm12360 ... At least i.MX53 has errata ENGcm12360: Occurs when a pending command which issues busy is completed. For a command with R1b response, the proper software sequence is to poll the DLA for R1b commands to determine busy state completion. The DLA polling is not working properly for the ESDHC module. This is relevant for all eSDHC ports (eSDHC1-4 ports) DLA bit in PRSSTAT register cannot be polled to wait for busy state completion. Updated block guide to reflect that DLA is not applicable to detect busy state, instead, should poll bit 24 in PRSSTAT register (DLSL[0] bit) to check that wait busy state is over.

2013-06-03	2302fc6 Browse files » mci: rename capabilities flags ... Use MMC_CAP_ names instead of MMC_MODE_.

	93b1578 Browse files » mci i.MX esdhc: Fix clock divider calculation ... This updates the i.MX esdhc divider settings to FSLs U-Boot. Current timings work fine for SD cards, but not for eMMC. Although the calculation is fine according to the datasheet and reading from eMMC works, writing is broken. Atleast on i.MX53/tqma53. With this patch the result is the same, but uses different divider values to achieve it. While at it, replace the udelay with a busy-loop.

	bd1bf53 Browse files » mci: imx-esdhc: factor out common sdhci registers ... This gives the SDHCI specific registers a common name and moves them to a separate file for use by other SDHCI like drivers. The SDHCI spec has some 16bit and 8bit registers. The i.MX accesses these as 32bit registers. These register defines now are named after the SDHCI registers they combine into one, for example: SDHCI_HOST_CONTROL__POWER_CONTROL__BLOCK_GAP_CONTROL is the 32bit version of the SDHCI registers HOST_CONTROL, POWER_CONTROL and BLOCK_GAP_CONTROL.
