2017-06-20mmc: core: Remove MMC_CAP2_HC_ERASE_SZUlf Hansson1-3/+1
The MMC_CAP2_HC_ERASE_SZ is used only by a few mmc host drivers. Its intent is to enable eMMC's high-capacity erase size, as to improve the behaviour of the erase operations. We should strive to avoid software configuration options that aren't necessary, but instead deploy common behaviours. For these reasons, let's remove the capability bit for MMC_CAP2_HC_ERASE_SZ and make it the default behaviour. Note that this change doesn't affect eMMCs supporting trim/discard, because these commands operates on sectors and takes precedence over erase commands.

This patch applies customized PCI_DEVICE_ macros to specify the pci_ids instead of open-coding them within the sdhci-pci driver.

2017-03-23mmc: sdhci-pci: Do not disable interrupts in sdhci_intel_set_powerAdrian Hunter1-0/+4
Disabling interrupts for even a millisecond can cause problems for some devices. That can happen when Intel host controllers wait for the present state to propagate. The spin lock is not necessary here. Anything that is racing with changes to the I/O state is already broken. The mmc core already provides synchronization via "claiming" the host. Although the spin lock probably should be removed from the code paths that lead to this point, such a patch would touch too much code to be suitable for stable trees. Consequently, for this patch, just drop the spin lock while waiting.

Intel BXT/APL use a card detect GPIO however the host controller will not enable bus power unless it's card detect also reflects the presence of a card. Unfortunately those 2 things race which can result in commands not starting, after which the controller does nothing and there is a 10 second wait for the driver's 10-second timer to timeout. That is fixed by having the driver look also at the present state register to determine if the card is present. Consequently, provide a 'get_cd' mmc host operation for BXT/APL that does that.
