1 * The simple MMC power sequence provider
3 The purpose of the simple MMC power sequence provider is to supports a set of
4 common properties between various SOC designs. It thus enables us to use the
5 same provider for several SOC designs.
8 - compatible : contains "mmc-pwrseq-simple".
11 - reset-gpios : contains a list of GPIO specifiers. The reset GPIOs are asserted
12 at initialization and prior we start the power up procedure of the card.
13 They will be de-asserted right after the power has been provided to the
15 - clocks : Must contain an entry for the entry in clock-names.
16 See ../clocks/clock-bindings.txt for details.
17 - clock-names : Must include the following entry:
18 "ext_clock" (External clock provided to the card).
19 - post-power-on-delay-ms : Delay in ms after powering the card and
20 de-asserting the reset-gpios (if any)
21 - power-off-delay-us : Delay in us after asserting the reset-gpios (if any)
22 during power off of the card.
