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.
