The pin data are implemented for old SoCs to specify the bit shift of the IECTRL register. They are not wortwhile given the required memory footprint. Delete all the pin data and enable all bits of the IECTRL register. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory.

2017-10-01rockchip: pinctrl: rk3368: add pinctrl for SDMMC0Philipp Tomsich
Apparently, our earlier assumption that the BROM will always set up the iomux for SDcard communication does not always hold true: when booting U-Boot from the on-module (on the RK3368-uQ7) eMMC, the SDcard pins are not set up and need to be configured by the pinctrl driver to allow SD card access. This change implements support for setting up the SDMMC pins in pinctrl for the RK3368.

2017-09-28pinctrl: rmobile: Add Renesas RCar pincontrol driverMarek Vasut
Add PFC pincontrol driver for the Renesas RCar Gen3 R8A7795 and R8A7796 SoCs. This driver uses the PFC pin tables from Linux, thus letting us share the occassional fixes to those tables. This driver also has a DT support, so the pinmux is configured from DT instead of the ad-hoc setup in board file. This driver is meant to replace the pinmux part of SH_GPIO_PFC driver.

There is no real reason to keep the bit-definitions for the IOMUX in the grf header file (which defines the register layout of the GRF block): these should only be used by our pinctrl driver (with the possible exception of early debug-init code in TPL/SPL).

The RK3368 has two SD/MMC controllers that can be used from U-Boot both during SPL and for booting an OS from the full bootloader stage.

Currently, drive-strenght to 12ma are described and supposed to be used on RK3288. However, the pinctrl driver for this SoC only handles muxing and pull up/pull down via PU/PD control registers.
