The following speed modes are now supported in J7200 SoC,
- HS200 and HS400 modes at 1.8 V card voltage, in MMCSD0 subsystem [1].
- UHS-I speed modes in MMCSD1 subsystem [1].
Add support for UHS-I modes by adding voltage regulator device tree nodes
and corresponding pinmux details, to power cycle
From: Faiz Abbas
There are 6 gpio instances inside SoC with 2 groups as show below:
Group one: wkup_gpio0, wkup_gpio1
Group two: main_gpio0, main_gpio2, main_gpio4, main_gpio6
Only one instance from each group can be used at a time. So use main_gpio0
and wkup_gpio0 in current linux conte
From: Faiz Abbas
There are 4 instances of gpio modules in main domain:
gpio0, gpio2, gpio4 and gpio6

virtual worlds. Each of these modules I/O pins are muxed within the
group. Exactly one module can be selected to contr
The following series of patches
- Add support for GPIO subsystem in main and wakeup domains.
- Add voltage regulator device tree nodes and their corresponding pinmux
to support power cycle and voltage switch required for UHS-I modes
- sets respective tags in sdhci0 node to support higher speeds

The commit e0546fd8b748 ("usbip: tools: Start using VUDC backend in

corresponding options are not documented in man page.
This commit documents the options and provides examples on device mode.
