mmc: sdhci: Change prototype of set_delay to return errors

2021-08-06T07:35:34+00:00

set_delay() has return type as void. If there are any errors while setting tapdelay's it won't be able to return them. Change the prototype of set_delay() in sdhci_ops structure and return the errors from wherever it is called. Signed-off-by: Ashok Reddy Soma Reviewed-by: Jaehoon Chung Signed-off-by: Michal Simek

mmc: sdhci: Add helper functions for UHS modes

2021-02-04T15:07:57+00:00

Add a set_voltage() function which handles the switch from 3.3V to 1.8V for SD card UHS modes. Signed-off-by: Faiz Abbas Signed-off-by: Aswath Govindraju Reviewed-by: Jaehoon Chung

dm: treewide: Rename dev_get_platdata() to dev_get_plat()

Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08+00:00

We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25+00:00

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass

Revert "mmc: zynq: parse dt when probing"

2020-10-27T07:13:33+00:00

This reverts commit 942b5fc03218d1c94468fc658e7dec65dabcc830. This is partial revert of the above commit. mmc_of_parse() is reading no-1-8-v from device tree and if set, it is clearing the UHS speed capabilities of cfg->host_caps. cfg->host_caps &= ~(UHS_CAPS | MMC_MODE_HS200 | MMC_MODE_HS400 | MMC_MODE_HS400_ES); This is still missing to clear UHS speeds like SDHCI_SUPPORT_SDR104, SDHCI_SUPPORT_SDR50 and SDHCI_SUPPORT_DDR50. Even if we clear the flags SDHCI_SUPPORT_XXX in mmc_of_parse(), these speed flags are getting set again in cfg->host_caps in sdhci_setup_cfg(). The reason for this is, SDHCI_SUPPORT_XXX flags are cleared only if controller is not capable of supporting MMC_VDD_165_195 volts. if (caps & SDHCI_CAN_VDD_180) cfg->voltages |= MMC_VDD_165_195; if (!(cfg->voltages & MMC_VDD_165_195)) caps_1 &= ~(SDHCI_SUPPORT_SDR104 | SDHCI_SUPPORT_SDR50 | SDHCI_SUPPORT_DDR50); It means "no-1-8-v", which is read from DT is not coming in to effect. So it is better we keep the host quirks(SDHCI_QUIRK_NO_1_8_V) to clear UHS speeds based on no-1-8-v from device tree. Hence revert the functionality related to no-1-8-v only, rest is fine in the patch. Signed-off-by: Ashok Reddy Soma Signed-off-by: Michal Simek Reviewed-by: Jaehoon Chung Reviewed-by: Peng Fan

mmc: sdhci: move the ADMA2 table handling into own module

mmc: zynq: parse dt when probing

2020-04-27T11:53:13+00:00

Currently, the entry "bus-width = <8>" in the ZynqMP's sdhci nodes is not evaluated. This results in the bus width staying at its default value (4 bit in HS200 mode). Fix this by calling mmc_of_parse. This function also checks for the "no-1-8-v" and "max-frequency" entries. Remove the handling of those nodes from this driver.
