Best to remove them, IMO.

First, we have converted the MMC block device from using the legacy blk interface into using the modern blkmq interface. Not only do we get all the nice effects from using blkmq, but it also means that new fresh nice code replaces old rusty code. Great news to everybody that cares about MMC/SD! It should also be noted that converting to blkmq has not been trivial, mostly because of that we have been carrying too much of MMC specific optimizations for the I/O request path, rather than striving to move these to the generic blk layer. Hopefully we won't be doing that mistake, ever again. Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro), who both have been working on this for quite some time! Second, on top of the blkmq deployment, we have enabled full support the eMMC command queuing feature, introduced in the eMMC v.5.1 spec. This also includes an implementation of a host driver library, supporting the corresponding CQHCI HW. Ideally, those controllers that supports CQHCI should only need some minor adaptations to make this play. So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan driver used on Rockchip RK3399, have enabled support for eMMC command queueing. Worth to highlight is also that, implementing the eMMC command queuing support has been a collaborative effort, as several people from Codeaurora, Rockchip, Intel and Linaro have been involved. However, the work has been driven by Adrian Hunter (Intel). In some shadow of the above, here are the rest of the highlights: MMC core: - Don't remove non-removable cards during system suspend - Add a slot-gpio helper to check capability of GPIO WP detection MMC host: - sdhci: Cleanups and improvements of some wakeup related code - sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy - sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT - sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400 - sdhci_f_sdh30: Add ACPI support - sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume - sdhci-of-esdhc: A few minor fixes - mmci: Add support for new STM32 variant - renesas_sdhi: enable R-Car D3 (r8a77995) support - tmio/renesas_sdhi: Re-structuring, cleanups and modernizations" * tag 'mmc-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: (96 commits) mmc: mmci: fix error return code in mmci_probe() mmc: davinci: suppress error message on EPROBE_DEFER mmc: davinci: dont' use module_platform_driver_probe() mmc: tmio: hide unused tmio_mmc_clk_disable/tmio_mmc_clk_enable functions mmc: mmci: Add STM32 variant mmc: mmci: Add support for setting pad type via pinctrl mmc: mmci: Don't pretend all variants to have OPENDRAIN bit mmc: mmci: Don't pretend all variants to have MCI_STARBITERR flag mmc: mmci: Don't pretend all variants to have MMCIMASK1 register mmc: tmio: refactor .get_ro hook mmc: slot-gpio: add a helper to check capability of GPIO WP detection mmc: tmio: remove dma_ops from tmio_mmc_host_probe() argument mmc: tmio: move {tmio_}mmc_of_parse() to tmio_mmc_host_alloc() mmc: tmio: move clk_enable/disable out of tmio_mmc_host_probe() mmc: tmio: ioremap memory resource in tmio_mmc_host_alloc() mmc: sh_mmcif: remove redundant initialization of 'opc' mmc: sdhci: Rework sdhci_enable_irq_wakeups() mmc: sdhci: Handle failure of enable_irq_wake() mmc: sdhci: Stop exporting sdhci_enable_irq_wakeups() mmc: sdhci-pci: Use device wakeup capability to determine MMC_PM_WAKE_SDIO_IRQ capability ... 2018-01-16T07:21:56+00:00 Shawn Lin shawn.lin@rock-chips.com 2018-01-16T03:43:51+00:00 urn:sha1:84362d79f436f12d1d9b9640a633de1b684a2609 Add CQHCI initialization and implement CQHCI operations for Arasan SDHCI variant host, namely arasan,sdhci-5.1, which is used by Rockchip RK3399 platform.

Given that mmc_of_parse() has already been made ACPI/DT agnostic, making the SDH30 driver ACPI capable is actually rather simple: all we need to do is make the call to sdhci_get_of_property() [which does not set any properties we care about] and the clock handling dependent on whether we are dealing with a DT device, and exposing the ACPI id via the platform_driver struct and the module metadata.
