mmc: sdhci-*: Don't emit error msg if sdhci_add_host() fails I noticed below error msg with sdhci-pxav3 on some berlin platforms: [.....] sdhci-pxav3 f7ab0000.sdhci failed to add host It is due to getting related vmmc or vqmmc regulator returns -EPROBE_DEFER. It doesn't matter at all but it's confusing. >From another side, if driver probing fails and the error number isn't -EPROBE_DEFER, the core will tell us something as below: [.....] sdhci-pxav3: probe of f7ab0000.sdhci failed with error -EXX So it's not necessary to emit error msg if sdhci_add_host() fails. And some other sdhci host drivers also have this issue, let's fix them together.

This avoids some spurious warnings like "Got data interrupt 0x00000002 even though no data operation was in progress" Testing on stih410-b2120 board achieves the following speeds with HS200 eMMC card. max-frequency = 200Mhz /dev/mmcblk0p1: Timing buffered disk reads: 270 MB in 3.02 seconds = 89.54 MB/sec max-frequency = 100Mhz root@debian-armhf:~# hdparm -t /dev/mmcblk0p1 /dev/mmcblk0p1: Timing buffered disk reads: 210 MB in 3.00 seconds = 70.00 MB/sec max-frequency = 50Mhz root@debian-armhf:~# hdparm -t /dev/mmcblk0p1 /dev/mmcblk0p1: Timing buffered disk reads: 118 MB in 3.00 seconds = 39.28 MB/sec This is better than the 3.10 kernel which achieves 77.59 MB/sec at 200Mhz clock (same board/soc/eMMC).

mmc: sdhci-st: Add sdhci_st_set_uhs_signaling function. To allow UHS modes to work properly we need to provide the st specific set_uhs_signaling callback function. This function differs from the generic sdhci_set_uhs_signaling callback in that we need to configure the correct delay depending on the UHS mode, and also set the V18_EN bit.

mmc: sdhci-st: Add delay management functions for top registers (eMMC). Due to the tight timing constraints in some UHS modes, it is required to have some delay management in the design. Two types of delay management are supported in the HW: - 1) Static delay management 2) Dynamic delay management NB: The delay management is only there when eMMC interface is selected. 1: Static delay management: is used to provide PVT dependent static delay on the clock/data lines to manage setup/hold requirements of the interface. The maximum delay possible is 3.25ns. These delays are PVT dependent, and thus delay values applied are not accurate and vary across provcess voltage and temperature range. Due to this these delays must not be used on the very time critical paths. 2. Dynamic delay locked loop (DLL): is used to provide dynamic delay management. The advantage of DLL is that it provides accurate & PVT indepedent delay. The DLL is used to provide delay on the loopback clock on "Read Path" to capture read data reliably. On TX path the clock on which output data is transmitted is delayed, resulting in delay of TX data.

mmc: sdhci-st: Add support for de-asserting reset signal and top regs resource STiH407 family SoC's can have a reset signal for the controller which needs to be managed. Also the eMMC controller has some additional 'top' memory mapped registers which are used to manage the dynamic and static delay required for UHS modes. This patch adds support for creating the mapping, which will be used by subsequent patches.
