[PATCH v2 12/14] mci: sdhci: add tuning support

The arasan SDHCI driver doesn't use MMC tuning but SDHCI tuning. Both are not supported yet in barebox. Add SDHCI tuning support from linux v6.7. Signed-off-by: Steffen Trumtrar Signed-off-by: Ahmad Fatoum --- drivers/mci/sdhci.c | 275 +++-

[PATCH v2 13/14] mci: arasan-sdhci: add HS200 tuning support on ZynqMP

The ZynpMP 8.9a has an Arasan IP core that supports HS200 tuning. Register the callback with the mci-core. Arasan uses the SDHCI tuning method. Signed-off-by: Steffen Trumtrar Reviewed-by: Ahmad Fatoum --- drivers/mci/arasan-sdhci.c | 62 +++--- 1 file

[PATCH v2 14/14] mci: sdhci: replace sdhci_wait_idle

Linux uses a different sdhci_wait_idle function than what barebox currently does. For HS200 support, the linux version needs to be used. As currently only arasan-sdhci is tested with HS200, keep the old sdhci_wait_idle as sdhci_wait_idle_data and convert all users of it. Signed-off-by: Ahmad

[PATCH v2 09/14] mci: core: parse more host capabilities from DT

[PATCH v2 04/14] include: mci: sync mci_timing with linux

The timings are used to check if mci_host->timing is equal to one of this values. Linux uses a different numbering. Adapt that for compatability. Signed-off-by: Steffen Trumtrar Reviewed-by: Ahmad Fatoum --- include/mci.h | 18 ++ 1 file changed, 10 insertions(+), 8

[PATCH v2 10/14] mci: mci-core: add HS200 support

HS200 is a timing mode for eMMCs to work 8bit with 200MHz clocks. To be used, drivers need to set the correct drive strength, clock phases and then SDHCI can start tuning for HS200. Signed-off-by: Steffen Trumtrar --- drivers/mci/Kconfig| 7 ++ drivers/mci/mci-core.c | 257

[PATCH v2 00/14] mci: add HS200 support for eMMCs

This series adds support for HS200 mode to mci-core and sdhci. As the host driver also needs to handle clock setup, pin control and host specific tuning, this series only adds HS200 support to the Arasan SDHCI driver. Tested on: ZynqMP Compile tested: for ZynqMP with/without CONFIG_MCI_TUNING
