[RFC 0/3] mmc: sdhci: pass signal voltage as an argument to ->voltage_switch()

[Vaibhav Hiremath]

In order to do particular voltage specific configuration in
sdhci_ops->voltage_switch() callback function, we need to
pass respective voltage value as well.

So this patch series pass signal voltage to the controller
specific ->voltage_switch() callback.
Adds controller specific configuration for other voltages as well,
and add implementation for ->voltage_switch to pxav3 driver.


Note:
Currently ->voltage_switch() callback is only supported
in f_sdh30 driver. And I am not sure on the dependency of execution
sequence for that device. I could have moved ->voltage_switch() call
at one common place (above/below), but was not quite sure about it.
So, replicated/duplicated the call for other voltages.


Vaibhav Hiremath (3):
  mmc: sdhci: pass signal_voltage as an argument to voltage_switch
    callback
  mmc: sdhci: add host_ops->voltage_switch callback for all other
    voltages
  mmc: sdhci-pxav3: Add ->voltage_switch callback support
