[PATCH 00/10] Raspberry Pi vmmc regulator support

[PATCH 00/10] Raspberry Pi vmmc regulator support

[Nicolas Saenz Julienne]

The series snowballed into adding a new quirk, as I reliased
sdhci-iproc's behaviour is not that uncommon.

Based on Phil Elwell's work in the downstream Raspberry Pi kernel.

We don't really want to replace callbacks by quirks.

Replace sdhci_milbeaut_set_power() etc by a common fn in sdhci.c if you want.

[PATCH 02/10] mmc: sdhci: milbeaut: Use quirk instead of custom set_power()

[Nicolas Saenz Julienne]

With the introduction of SDHCI_QUIRK2_SET_BUS_VOLTAGE there is no need
to use a custom set_power() implementation as the quirk takes care of
configuring the bus voltage register even when powering trough a
regulator.

to use a custom set_power() implementation as the quirk takes care of
configuring the bus voltage register even when powering trough a
regulator.

[PATCH 07/10] mmc: sdhci: am654: Use quirk instead of custom set_power()

[Nicolas Saenz Julienne]

With the introduction of SDHCI_QUIRK2_SET_BUS_VOLTAGE there is no need
to use a custom set_power() implementation as the quirk takes care of
configuring the bus voltage register even when powering trough a
regulator.

[PATCH 08/10] mmc: sdhci: Unexport sdhci_set_power_noreg()

[Nicolas Saenz Julienne]

There are no users left and, ideally, it's not a function that should be
called outside of the core sdhci code.

As sdhci_set_power_reg() depends on sdhci_set_power_noreg() it was moved
underneath it.

[PATCH 09/10] mmc: sdhci: iproc: Use SDHCI_QUIRK2_SET_BUS_VOLTAGE on bcm2711

[Nicolas Saenz Julienne]

Although vmmc is provided by a regulator, bcm2711's sdhci-iproc needs
its bus voltage register to be set to a non-zero value. Failure to do so
turns the core off.
