Subject: [PATCH v2 00/16] mmc: sdhci-omap: Add UHS/HS200 mode support
Date: Mon, 5 Feb 2018 18:20:13 +0530 [thread overview]
Message-ID: <20180205125029.21570-1-kishon@ti.com> (raw)
Add UHS/HS200 mode support in sdhci-omap. The programming sequence
for voltage switching, tuning is followed from AM572x TRM
http://www.ti.com/lit/ug/spruhz6i/spruhz6i.pdf
(Similar to all AM57x/DRA7x SoCs). The patch series also implements
workaround for errata published in
http://www.ti.com/lit/er/sprz429k/sprz429k.pdf.
It also includes a pdata-quirk patch since both pdata-quirks and
sdhci-omap uses struct sdhci_omap_platform_data.
The dt patches enabling UHS/HS200 will follow this series.
Changes from v1:
*) Only poll on DAT0 and DATI for card_busy status
*) Cleanup iodelay patch as suggested by Tony.
*) Added quirk to disable HW timeout
*) Use the existing data timer but program a relatively accurate
SW timeout value (Impacts all platforms)
*) Fix a bug in sdhci which was using data_timer for non data line
commands
I've tested on dra72-evm, dra7xx-evm, dra71-evm, am572x-idk, am571x-idk
dra76-evm, am57xx-evm and k2g-evm.
I've also pushed the series (along with dt) to
https://github.com/kishon/linux-wip.git sdhci_uhs_v2
