Start a list of SD vendors and products.

Christos Zoulas removed his name from advertising clauses and copyrights of some files in NetBSD. Make the same changes here.

Add hibernate IO path for sdmmc(4). This requires some help from the sdmmc chipset driver, currently only implemented in sdhc(4), but mostly uses the regular path. sdhc(4) also needed the ability to perform IO while cold.

Fixup bwfm(4) register bit regarding SDIO device suspend/resume.

On SDHC version 3.0 controllers the divisor doesn't have to be a power of two, but can be a multiple of two. Make use of this to achieve card clock frequencies closer to the target frequency.

Implement 64-bit DMA support in sdhc(4).

Improve how quirks are handled on sdhc(4)-compatible drivers. So far we have passed a modified version of the contents in the capabilities register if we wanted to override what sdhc(4) would otherwise read. Unfortunately there's a second capabilities register that we did not yet take into consideration, which is why to disable DDR50 support we created a quirk flag in the softc. The sdhc(4) ACPI nodes have a way to mask and set bits in both of the capabilities register, which is a flexible approach to solving that issue and using that for our sdhc(4) drivers even improves readability.

Allow suspend with root on sdmmc(4).

According to the SDIO Simplified Specification 3.0, a tuple length (aka link field) of 0 specifies an empty tuple body. This implies that a tuple length of 0 is actually allowed, so we don't need to error out if we encounter one. Seen on an SDIO-connected ath10k.

sdmmc(4): sdmmc_io_function_enable(): don't sleep on lbolt

5 years ago

Correct the bitmask that returns the function count. We missed a bit and thus only supported 4 functions instead of 8.

7 years ago

Return ENOMEM on malloc errors to prevent use of uninitialized stack memory. Cleanup error handling while here.

constify SCSI adapter entry points

First and foremost, avoid an obious race between two or more processes trying to get MMC commands through to the SD/MMC host controller via the emulated SCSI layer. This is achieved by ensuring exclusive access to the host controller for one process during any MMC command and during a sequence of commands at the sdmmc(4) layer.

Add support for eMMC HS200 mode. Loosely based on code from NetBSD.

Add bwfm chips to sdmmcdevs in order to get symbolic constants for them.
