2023-01-24mmc: sdhci-esdhc-imx: correct the tuning start tap and step settingHaibo Chen1-7/+15
commit 1e336aa0c0250ec84c6f16efac40c9f0138e367d upstream. Current code logic may be impacted by the setting of ROM/Bootloader, so unmask these bits first, then setting these bits accordingly.

2022-12-08mmc: sdhci: Fix voltage switch delayAdrian Hunter2-7/+56
commit c981cdfb9925f64a364f13c2b4f98f877308a408 upstream. Commit 20b92a30b561 ("mmc: sdhci: update signal voltage switch code") removed voltage switch delays from sdhci because mmc core had been enhanced to support them. However that assumed that sdhci_set_ios() did a single clock change, which it did not, and so the delays in mmc core, which should have come after the first clock change, were not effective. Fix by avoiding re-configuring UHS and preset settings when the clock is turning on and the settings have not changed. That then also avoids the associated clock changes, so that then sdhci_set_ios() does a single clock change when voltage switching, and the mmc core delays become effective. To do that has meant keeping track of driver strength (host->drv_type), and cases of reinitialization (host->reinit_uhs). Note also, the 'turning_on_clk' restriction should not be necessary but is done to minimize the impact of the change on stable kernels.

2022-12-08mmc: sdhci-esdhc-imx: correct CQHCI exit halt state checkSebastian Falbesoner1-1/+1
commit a3cab1d2132474969871b5d7f915c5c0167b48b0 upstream. With the current logic the "failed to exit halt state" error would be shown even if any other bit than CQHCI_HALT was set in the CQHCI_CTL register, since the right hand side is always true. Fix this by using the correct operator (bit-wise instead of logical AND) to only check for the halt bit flag, which was obviously intended here.

commit 39a72dbfe188291b156dd6523511e3d5761ce775 upstream. In mmc_select_voltage(), if there is no full power cycle, the voltage range selected at the end of the function will be on a single range (e.g. 3.3V/3.4V). To keep a range around the selected voltage (3.2V/3.4V), the mask shift should be reduced by 1. This issue was triggered by using a specific SD-card (Verbatim Premium 16GB UHS-1) on an STM32MP157C-DK2 board. This board cannot do UHS modes and there is no power cycle. And the card was failing to switch to high-speed mode. When adding the range 3.2V/3.3V for this card with the proposed shift change, the card can switch to high-speed mode.

When out of sync, we may trigger various timeouts. It's not typical to perform resets while CQE is enabled, but one particular case I hit commonly enough: mmc_suspend() -> mmc_power_off(). Typically we will eventually deactivate CQE (cqhci_suspend() -> cqhci_deactivate()), but that's not guaranteed -- in particular, if we perform a partial (e.g., interrupted) system suspend. The same bug was already found and fixed for two other drivers, in v5.7 and v5.9: 5cf583f1fb9c ("mmc: sdhci-msm: Deactivate CQE during SDHC reset") df57d73276b8 ("mmc: sdhci-pci: Fix SDHCI_RESET_ALL for CQHCI for Intel GLK-based controllers") The latter is especially prescient, saying "other drivers using CQHCI might benefit from a similar change, if they also have CQHCI reset by SDHCI_RESET_ALL."

2022-11-16mmc: cqhci: Provide helper for resetting both SDHCI and CQHCIBrian Norris1-0/+24
commit ebb5fd38f41132e6924cb33b647337f4a5d5360c upstream. Several SDHCI drivers need to deactivate command queueing in their reset hook (see sdhci_cqhci_reset() / sdhci-pci-core.c, for example), and several more are coming. Those reset implementations have some small subtleties (e.g., ordering of initialization of SDHCI vs. CQHCI might leave us resetting with a NULL ->cqe_private), and are often identical across different host drivers. We also don't want to force a dependency between SDHCI and CQHCI, or vice versa; non-SDHCI drivers use CQHCI, and SDHCI drivers might support command queueing through some other means. So, implement a small helper, to avoid repeating the same mistakes in different drivers. Simply stick it in a header, because it's so small it doesn't deserve its own module right now, and inlining to each driver is pretty reasonable. This is marked for -stable, as it is an important prerequisite patch for several SDHCI controller bugfixes that follow.

2022-10-30mmc: sdhci-tegra: Use actual clock rate for SW tuning correctionPrathamesh Shete1-1/+1
[ Upstream commit b78870e7f41534cc719c295d1f8809aca93aeeab ] Ensure tegra_host member "curr_clk_rate" holds the actual clock rate instead of requested clock rate for proper use during tuning correction algorithm. Actual clk rate may not be the same as the requested clk frequency depending on the parent clock source set. Tuning correction algorithm depends on certain parameters which are sensitive to current clk rate. If the host clk is selected instead of the actual clock rate, tuning correction algorithm may end up applying invalid correction, which could result in errors Fixes: ea8fc5953e8b ("mmc: tegra: update hw tuning process") Signed-off-by: Aniruddha TVS Rao <anrao@nvidia.com> Signed-off-by: Prathamesh Shete <pshete@nvidia.com> Acked-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Thierry Reding <treding@nvidia.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20221006130622.22900-4-pshete@nvidia.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Sasha Levin <sashal@kernel.org>

[ Upstream commit 4de95950d970c71a9e82a24573bb7a44fd95baa1 ] The Snapdragon 670 has the same quirk as Snapdragon 845 (needing to restore the dll config). Add a compatible string check to detect the need for this.

commit 6e141772e6465f937458b35ddcfd0a981b6f5280 upstream. The Spreadtrum controller supports 100KHz minimal clock rate, which means that the current value 400KHz is wrong. Unfortunately this has also lead to fail to initialize some cards, which are allowed to require 100KHz to work. So, let's fix the problem by changing the minimal supported clock rate to 100KHz.

2022-10-15mmc: core: Terminate infinite loop in SD-UHS voltage switchBrian Norris1-1/+2
[ Upstream commit e9233917a7e53980664efbc565888163c0a33c3f ] This loop intends to retry a max of 10 times, with some implicit termination based on the SD_{R,}OCR_S18A bit. Unfortunately, the termination condition depends on the value reported by the SD card (*rocr), which may or may not correctly reflect what we asked it to do. Needless to say, it's not wise to rely on the card doing what we expect; we should at least terminate the loop regardless. So, check both the input and output values, so we ensure we will terminate regardless of the SD card behavior. Note that SDIO learned a similar retry loop in commit 0797e5f1453b ("mmc: core: Fixup signal voltage switch"), but that used the 'ocr' result, and so the current pre-terminating condition looks like: rocr & ocr & R4_18V_PRESENT (i.e., it doesn't have the same bug.) This addresses a number of crash reports seen on ChromeOS that look like the following: ... // lots of repeated: ... <4>[13142.846061] mmc1: Skipping voltage switch <4>[13143.406087] mmc1: Skipping voltage switch <4>[13143.964724] mmc1: Skipping voltage switch <4>[13144.526089] mmc1: Skipping voltage switch <4>[13145.086088] mmc1: Skipping voltage switch <4>[13145.645941] mmc1: Skipping voltage switch <3>[13146.153969] INFO: task halt:30352 blocked for more than 122 seconds. ...
