2021-10-21mmc: zynq_sdhci: Add xilinx_pm_request weak functionT Karthik Reddy1-0/+6
Mini emmc does not use any pmufw and ZYNQMP_FIRMWARE is disabled. xilinx_pm_request() will not be compiled and causes undefined reference to `xilinx_pm_request' error. So add a weak function in zynq_sdhci.c file.

2021-08-26mmc: zynq_sdhci: Wait till sd card detect state is stableT Karthik Reddy1-0/+19
As per SD spec when SD host controller is reset, it takes 1000msec to detect the card state. In case, if we enable the sd bus voltage & card detect state is not stable, then host controller will disable the sd bus voltage. In case of warm/subsystem reboot, due to unstable card detect state host controller is disabling the sd bus voltage to sd card causing sd card timeout error. So we wait for a maximum of 1000msec to get the card detect state stable before we enable the sd bus voltage. This current fix is workaround for now, this needs to be analysed further. Zynqmp platform should behave the same as Versal, but we did not encounter this issue as of now. So we are fixing it for Versal only.

2021-08-26mmc: zynq_sdhci: Add xilinx_pm_request() method to set tapdelaysAshok Reddy Soma1-14/+59
Currently xilinx sdhci driver is using zynqmp_mmio_write() to set tapdelay values and DLL resets. Continue to use this for SPL and mini U-Boot where U-Boot will be executed at EL3 level. Use firmware call xilinx_pm_request() using appropriate arguments to set input/output tapdelays and also for DLL resets in regular flow(EL2). Host driver should explicitly request DLL reset before ITAP (assert DLL) and after OTAP (release DLL) to avoid issues in some cases. Also handle error return where possible.

2020-10-27Revert "mmc: zynq: parse dt when probing"Ashok Reddy Soma1-0/+5
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.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

The zynq_sdhci controller driver use CONFIG_ZYNQ_SDHCI_MAX_FREQ as base clock frequency but this clock is not fixed and depends on the hardware configuration. Additionally the value of CONFIG_ZYNQ_SDHCI_MAX_FREQ doesn't match the real base clock frequency of SDIO_FREQ. Use the clock framework to determine the frequency at run time.
