* rockchip: rk3188: explicitly set vcc_sd0 pin to gpio on rk3188-radxarockHeiko Stuebner2018-10-021-0/+8
| | | | | | | | | | | | | | | | | | | | It is good practice to make the setting of gpio-pinctrls explicitly in the devicetree, and in this case even necessary. Rockchip boards start with iomux settings set to gpio for most pins and while the linux pinctrl driver also implicitly sets the gpio function if a pin is requested as gpio that is not necessarily true for other drivers. The issue in question stems from uboot, where the sdmmc_pwr pin is set to function 1 (sdmmc-power) by the bootrom when reading the 1st-stage loader. The regulator controlled by the pin is active-low though, so when the dwmmc hw-block sets its enabled bit, it actually disables the regulator. By changing the pin back to gpio we fix that behaviour.

* SPDX: Convert all of our multiple license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>
* rockchip: rk3188: add -u-boot.dtsi for rock-rk3188Kever Yang2018-04-251-5/+1

* rockchip: rk3188: Add Radxa Rock boardHeiko Stübner2017-04-041-0/+382
The Rock is a RK3188 based single board computer by Radxa. Currently it still relies on the proprietary DDR init and cannot use the generic SPL, but at least is able to boot a linux kernel and system up to a regular login prompt.
