Subject: [PATCH v2 0/6] Add support of inverting power control and some minor cleanup
Date: Sun, 7 Aug 2016 09:33:38 +0800 [thread overview]
Message-ID: <1470533618-16312-1-git-send-email-shawn.lin@rock-chips.com> (raw)
By default, dw_mmc outputs high level voltage to indicate powering
up the card and outputs low level vcltage to indicate powering
off the card. But that is not always correct. The power io should
be able to control different kind of hw components to supply or
cutoff power to the card. We have boards that need this patchset
to make the power control correct. Meanwhile let's expose it to
DT for board-specific usage.
Changes in v2:
- fix copy-paste err and typo
Shawn Lin (6):
dt-bindings: rockchip-dw-mshc: add description of
rockchip,power-invert
mmc: dw_mmc: cleanup power setting of set_ios callback
mmc: dw_mmc: split out dw_mci_set_power
mmc: dw_mmc: split out dw_mci_set_power_reg
mmc: dw_mmc: support inverted power control
mmc: dw_mmc-rockchip: add parsing of power control from DT
