Hi Dirk,

Ah, ES2.0. That's the missing information. Yup, is on the todo-list. I
will try to test your patch on my Salvator-XS board today.

Ok, thanks :)

Your patch on top of v4.13-rc5 makes SDHI work on my Salvator-XS with a


Please feel free to forward it to the correct channels for merge, then.


H3 ES2.0. It detects the eMMC and I can mount SD cards on both slots and
checksum large files.


Hmm, sounds like I have to search on my custom board why there is not output at all, then :(


It works, now :)

Just for the logs:

While creating the defconfig for testing v4.13-rc5 somehow

CONFIG_GPIOLIB=y
CONFIG_GPIO_RCAR=y

was dropped. Without GPIO support the statement

of_get_fixed_voltage_config(...) {
	...
	config->gpio = of_get_named_gpio(np, "gpio", 0);
	if ((config->gpio < 0) && (config->gpio != -ENOENT)) {

failed, resulting in failing regulator support. Without regulator support

tmio_mmc_init_ocr()

fails (silently!). And with this the whole RCar3 SDHI, without any error message.

Enabling GPIO does fix the issue.

Many thanks for your help!

Dirk

P.S.: Will try to send the pin mux patch tomorrow.
