Subject: [PATCH v3 00/11] mmc: sdhci-omap: Add UHS/HS200 mode support
Date: Wed, 7 Mar 2018 18:50:09 +0530 [thread overview]
Message-ID: <20180307132020.30951-1-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
patches are created on top of
git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git next
Patches in v2 already applied to mmc -next are dropped from the
series.
Changes from v2:
*) Changed SW timeout logic as per Adrians's suggestion
*) Validated SDIO with the current patches (added a couple of fixes
found while adding SDIO support).
*) Used soc_device_match() instead of pdata-quirks as per Tony's
suggestions.
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
