When changing SD card voltage signal for Spreadtrum SD host controller,
it also need to switch related pin's state. Thus add pinctrl properties'
description in documentation.

This patch set is used to optimize voltage switch for the
Spreadtrum SD host controller.
Any comments are welcome. Thanks.
Baolin Wang (3):
mmc: sdhci-sprd: Add start_signal_voltage_switch ops
dt-bindings: mmc: sprd: Add pinctrl support
mmc: sdhci-sprd: Add pin control support for voltage
For Spreadtrum SD card voltage switching, besides regulator setting,
it also need switch related pin's state to output corresponding voltage.
This patch adds pin control operation to support voltage switch.

For the Spreadtrum SD host controller, when we changed the clock to be
more than 52M, we should enable the PHY DLL which is used to track the
clock frequency to make the clock work more stable. Otherwise deviation
may occur of the higher clock.

'2x_enable' to make the SD host controller work well.

gate clock '2x_enable' to make the SD host controller work well. Thus add
