mmc: sdhci_omap: Fix TI SoC dependencies

2024-01-25T23:45:07Z

[ Upstream commit 09f164d393a6671e5ff8342ba6b3cb7fe3f20208 ] The sdhci_omap is specific to older TI SoCs, update the dependencies for those SoCs and compile testing. While we're at it update the text to reflect the wider range of supported TI SoCS the driver now supports.

mmc: sdhci-sprd: Fix eMMC init failure after hw reset

2024-01-03T10:24:03Z

Some eMMC devices that do not close the auto clk gate after hw reset will cause eMMC initialization to fail. Let's fix this.

mmc: meson-mx-sdhc: Fix initialization frozen issue

2023-12-07T13:08:19Z

Commit 4bc31edebde5 ("mmc: core: Set HS clock speed before sending HS CMD13") set HS clock (52MHz) before switching to HS mode. For this freq, FCLK_DIV5 will be selected and div value is 10 (reg value is 9). Then we set rx_clk_phase to 11 or 15 which is out of range and make hardware frozen. After we send command request, no irq will be interrupted and the mmc driver will keep to wait for request finished, even durning rebooting. So let's set it to Phase 90 which should work in most cases. Then let meson_mx_sdhc_execute_tuning() to find the accurate value for data transfer. If this doesn't work, maybe need to define a factor in dts.

mmc: sdhci-pci-gli: Disable LPM during initialization

2023-11-23T17:01:12Z

To address IO performance commit f9e5b33934ce ("mmc: host: Improve I/O read/write performance for GL9763E") limited LPM negotiation to runtime suspend state. The problem is that it only flips the switch in the runtime PM resume/suspend logic. Disable LPM negotiation in gl9763e_add_host. This helps in two ways: 1. It was found that the LPM switch stays in the same position after warm reboot. Having it set in init helps with consistency. 2. Disabling LPM during the first runtime resume leaves us susceptible to the performance issue in the time window between boot and the first runtime suspend.

mmc: cqhci: Fix task clearing in CQE error recovery

2023-11-14T16:15:08Z

If a task completion notification (TCN) is received when there is no outstanding task, the cqhci driver issues a "spurious TCN" warning. This was observed to happen right after CQE error recovery. When an error interrupt is received the driver runs recovery logic. It halts the controller, clears all pending tasks, and then re-enables it. On some platforms, like Intel Jasper Lake, a stale task completion event was observed, regardless of the CQHCI_CLEAR_ALL_TASKS bit being set. This results in either: a) Spurious TC completion event for an empty slot. b) Corrupted data being passed up the stack, as a result of premature completion for a newly added task. Rather than add a quirk for affected controllers, ensure tasks are cleared by toggling CQHCI_ENABLE, which would happen anyway if cqhci_clear_all_tasks() timed out. This is simpler and should be safe and effective for all controllers.

mmc: cqhci: Increase recovery halt timeout

2023-11-14T16:15:07Z

Failing to halt complicates the recovery. Additionally, unless the card or controller are stuck, which is expected to be very rare, then the halt should succeed, so it is better to wait.

mmc: sdhci-pci-gli: GL9750: Mask the replay timer timeout of AER

2023-11-07T12:08:12Z

Due to a flaw in the hardware design, the GL9750 replay timer frequently times out when ASPM is enabled. As a result, the warning messages will often appear in the system log when the system accesses the GL9750 PCI config. Therefore, the replay timer timeout must be masked.
