Provide a whitelist for Gen3 SoC ES versions for both the SYS DMAC and internal DMAC variants of the SDHI driver. This is to allow drivers to only initialise for Gen3 SoC ES versions for which they are the appropriate DMAC implementation. Currently internal DMAC is the appropriate implementation for all supported Gen3 SoC ES versions. Signed-off-by:

pci_device_id are not supposed to change at runtime. All functions working with pci_device_id provided by <linux/pci.h> work with const pci_device_id. So mark the non-const structs as const.

sdhci uses CONFIG_MMC_DEBUG for showing ADMA descriptor when occurring ADMA error. And it's also used to dump the registers whenever calling sdhci_add_host. On one hand, I don't see any burden to always print the state ADMA descriptor as it's rare and will help folks better understand what was happening when seeing ADMA error. On the other, folks may be interested in checking some registers at probe time. So we remove the sdhci_dumpregs from __sdhci_add_host and print some really useful registers in sdhci_setup_host.

wbsd only use this to print some unsupported command. However the pr_warn should be enough for dynamic log control and CONFIG_MMC_DEBUG seems bogus here. Remove it. Signed-off-by:

We have removed all code depending on CONFIG_MMC_DEBUG from mmc core now. So it's safe to make CONFIG_MMC_DEBUG just for host drivers only and we expect to kill this option in the future. Signed-off-by:

There are lots of debug message in core.c which use pr_debug for better dynamic log level control. So it doesn't make sense for those print to still keep working only under CONFIG_MMC_DEBUG. Signed-off-by:

All the check within mmc_mrq_prep seems to be all-or-none proposition, so it doesn't make sense to only check the length of sglist only under the CONFIG_MMC_DEBUG context. I'd prefer to always keep the check there unconditionally. Signed-off-by:

The intention of this check was to prevent the conflict between hotplug and removing driver for whatever reason. Currently it doesn't improve anything and the following rescan process could still saftly perform the scan flow. So these code seems pointless now and let's remove them. Signed-off-by:

This adds deepest (Backup+Self-Refresh) PM support to the ATMEL SAMA5D2 SoC's SDHCI controller. When resuming from deepest state, it is required to restore preset registers as the registers are lost since VDD core has been shut down when entering deepest state on the SAMA5D2. The clocks need to be reconfigured as well. The other registers and init process are taken care of by the SDHCI core. Signed-off-by:

We got a warning: drivers/mmc/host/atmel-mci.c:1086:15: warning: variable 'sg_len' set but not used [-Wunused-but-set-variable] Ideally we should check to see if sg_len is zero but looking into the code closely, I didn't find any possible to do that as atmci_start_request didn't even deploy any error handling for its host->prepare_data hook. So even we return error value for iflags like what other host drivers did, for instance, sdhci and dwmmc, it still need some extra work to improve the code. Just remove it to silent the warning, although it isn't perfect. Signed-off-by:
