2019-12-18mmc: mmci: add threaded irq to abort DPSM of non-functional stateLudovic Barre
The stm32_sdmmc variant has build-in support for datatimeout for R1B requests. If a corresponding IRQ is raised, this triggers the DPSM to stay busy and remains in a non-functional state. Only a reset can bring it back to a functional state. Because a reset must be issued from non-atomic context, let's defer this to be managed from a threaded IRQ handler. Besides the reset, the threaded handler also calls mmc_request_done(), to finally complete the request.

2019-12-16mmc: spi: Toggle SPI polarity, do not hardcode itLinus Walleij
The code in mmc_spi_initsequence() tries to send a burst with high chipselect and for this reason hardcodes the device into SPI_CS_HIGH. This is not good because the SPI_CS_HIGH flag indicates logical "asserted" CS not always the physical level. In some cases the signal is inverted in the GPIO library and in that case SPI_CS_HIGH is already set, and enforcing SPI_CS_HIGH again will actually drive it low. Instead of hard-coding this, toggle the polarity so if the default is LOW it goes high to assert chipselect but if it is already high then toggle it low instead.

In the SAM9x60 SoC, there are only two clocks instead of three for the SDHCI device. The base clk is no longer provided, it is generated internally from the mult clk. The values of the base clk and mul in the capabilities registers may not reflect the reality as the mult clk is a programmable clock which can take several rates. As we can't trust those values, take them from the clock tree and update the capabilities according to. As we can have the same pitfall, in some cases, with the SAMA5D2 Soc, stop relying on capabilities too.

2019-12-16mmc: sdhci-of-esdhc: Revert "mmc: sdhci-of-esdhc: add erratum A-009204 support"Rasmus Villemoes
This reverts commit 5dd195522562542bc6ebe6e7bd47890d8b7ca93c. First, the fix seems to be plain wrong, since the erratum suggests waiting 5ms before setting setting SYSCTL[RSTD], but this msleep() happens after the call of sdhci_reset() which is where that bit gets set (if SDHCI_RESET_DATA is in mask). Second, walking the whole device tree to figure out if some node has a "fsl,p2020-esdhc" compatible string is hugely expensive - about 70 to 100 us on our mpc8309 board. Walking the device tree is done under a raw_spin_lock, so this is obviously really bad on an -rt system, and a waste of time on all. In fact, since esdhc_reset() seems to get called around 100 times per second, that mpc8309 now spends 0.8% of its time determining that it is not a p2020. Whether those 100 calls/s are normal or due to some other bug or misconfiguration, regularly hitting a 100 us non-preemptible window is unacceptable.

2019-12-16mmc: sdhci-msm: Correct the offset and value for DDR_CONFIG registerVeerabhadrarao Badiganti
The DDR_CONFIG register offset got updated after a specific minor version of sdcc V4. This offset change has not been properly taken care of while updating register changes for sdcc V5. Correcting proper offset for this register. Also updating this register value to reflect the recommended RCLK delay.

2019-12-16Revert "mmc: sdhci: Fix incorrect switch to HS mode"Faiz Abbas
This reverts commit c894e33ddc1910e14d6f2a2016f60ab613fd8b37. This commit aims to treat SD High speed and SDR25 as the same while setting UHS Timings in HOST_CONTROL2 which leads to failures with some SD cards in AM65x. Revert this commit. The issue this commit was trying to fix can be implemented in a platform specific callback instead of common sdhci code.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the "big" set of driver core patches for 5.5-rc1 There's a few minor cleanups and fixes in here, but the majority of the patches in here fall into two buckets: - debugfs api cleanups and fixes - driver core device link support for boot dependancy issues The debugfs api cleanups are working to slowly refactor the debugfs apis so that it is even harder to use incorrectly. That work has been happening for the past few kernel releases and will continue over time, it's a long-term project/goal The driver core device link support missed 5.4 by just a bit, so it's been sitting and baking for many months now. It's from Saravana Kannan to help resolve the problems that DT-based systems have at boot time with dependancy graphs and kernel modules. Turns out that no one has actually tried to build a generic arm64 kernel with loads of modules and have it "just work" for a variety of platforms (like a distro kernel). The big problem turned out to be a lack of dependency information between different areas of DT entries, and the work here resolves that problem and now allows devices to boot properly, and quicker than a monolith kernel.

Pull MMC updates from Ulf Hansson: "These are the updates for MMC and MEMSTICK for v5.5. Note that this also contains quite some additional changes reaching beyond both the MMC and MEMSTICK subsystems. This is primarily because of fixing an old regression for a WiFi driver based on the SDIO interface on an OMAP openpandora board MMC core: - Add CMD13 polling for MMC IOCTLS with R1B response. - Add common DT properties for clk-phase-delays for various speed modes. - Fix size overflow for mmc gp-partitions. - Re-work HW reset for SDIO cards, which also includes a re-work for Marvell's WiFi mwifiex SDIO func driver.
