MMC core:
- Capture correct oemid-bits for eMMC cards
- Fix error propagation for some ioctl commands
- Hold retuning if SDIO is in 1-bit mode
MMC host:
- mtk-sd: Use readl_poll_timeout_atomic to not "schedule while atomic"
- sdhci-msm: Correct minimum number of clocks
- sdhci-pci-gli: Fix LPM negotiation so x86/S0ix SoCs can suspend
- sdhci-sprd: Fix error code in sdhci_sprd_tuning()
mmc: core: Capture correct oemid-bits for eMMC cards
The OEMID is an 8-bit binary number rather than 16-bit as the current code
parses for. The OEMID occupies bits [111:104] in the CID register, see the
eMMC spec JESD84-B51 paragraph 7.2.3. It seems that the 16-bit comes from
the legacy MMC specs (v3.31 and before).
Let's fix the parsing by simply move to use 8-bit instead of 16-bit. This
means we ignore the impact on some of those old MMC cards that may be out
there, but on the other hand this shouldn't be a problem as the OEMID seems
not be an important feature for these cards.
