* mmc(4): Don't call bridge driver for timings not requiring tuningMarius Strobl2023-04-181-0/+9
| | | | | | | | | | | | The original idea behind calling into the bridge driver was to have the logic deciding whether tuning is actually required for a particular bus timing in a given slot as well as doing the sanity checking only on the controller layer which also generally is better suited for these due to say SDHCI_SDR50_NEEDS_TUNING. On another thought, not every such driver should need to check whether tuning is required at all, though, and not everything is SDHCI in the first place. Adjust sdhci{,_fsl_fdt}(4) accordingly, but keep sdhci_generic_tune() a bit cautious still.

* Extend device_get_property APIKornel Duleba2022-03-101-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | In order to support various types of data stored in device tree properties or ACPI _DSD packages, create a new enum so the caller can specify the expected type of a property they want to read, according to the binding. The bus logic will use that information to process the underlying data. For example in DT all integer properties are stored in BE format. In order to get constant results across different platforms we need to convert its endianness to match the host. Another example are ACPI_TYPE_INTEGER properties stored as uint64_t. Before this patch the ACPI logic would refuse to read them if the provided buffer was smaller than 8 bytes. Now this can be handled by using DEVICE_PROP_UINT32 type. Modify the existing consumers of this API to reflect the changes and update the man pages accordingly.

* mmc: Fix HS200/HS400 capability checkKornel Duleba2021-11-291-2/+4
| | | | | | | | | | | | | | | HS200 and HS400 speeds can be enabled either with 1.2, or 1.8V signaling voltage. Because of that we have four cabability flags: MMC_CAP_MMC_HS200_120, MMC_CAP_MMC_HS200_180, MMC_CAP_MMC_HS400_120, MMC_CAP_MMC_HS400_180. MMC logic only enables HS200/HS400 mode if both flags are set for the corresponding speed. Fix that by being more permissive in host timing cap check.

* mmc: Fix regression in 8a8166e5bcfb breaking Stratix 10 bootJessica Clarke2021-09-291-3/+3
| | | | | | | | | | | | | | | | The refactoring in 8a8166e5bcfb introduced a functional change that breaks booting on the Stratix 10, hanging when it should be attaching da0. Previously OF_getencprop was called with a pointer to host->f_max, so if it wasn't present then the existing value was left untouched, but after that commit it will instead clobber the value with 0. The dwmmc driver, as used on the Stratix 10, sets a default value before calling mmc_fdt_parse and so was broken by this functional change. It appears that aw_mmc also does the same thing, so was presumably also broken on some boards.

| | | | | | | | | | | | | | | | Buggy SD card drivers may attach and detach a mmc(4) driver instance in quick succession. In this case mmc(4) must disestablish its intrhook callback during detach. Thus, this change adds a call to config_intrhook_drain(), which blocks or does nothing if the intrhook is running or has already ran (the SD card was plugged in), and disestablishes the hook if it hasn't ran yet (the SD card was not plugged in).

| | | | | | | | | | | | | | | | | | | | | | bus_child_{pnpinfo,location} with sbuf Now that the upper layers all go through a layer to tie into these information functions that translates an sbuf into char * and len. The current interface suffers issues of what to do in cases of truncation, etc. Instead, migrate all these functions to using struct sbuf and these issues go away. The caller is also in charge of any memory allocation and/or expansion that's needed during this process. Create a bus_generic_child_{pnpinfo,location} and make it default. It just returns success. This is for those busses that have no information for these items. Migrate the now-empty routines to using this as appropriate.
