* ARM: tegra: pinmux naming consistency fixesStephen Warren2014-04-17-69/+71
| | | | | | | | | | | | | | | Clean up the naming of pinmux-related objects: * Refer to drive groups rather than pad groups to match the Linux kernel. * Ensure all pinmux API types are prefixed with pmux_, values (defines) are prefixed with PMUX_, and functions prefixed with pinmux_. * Modify a few type names to make their content clearer. * Minimal changes to SoC-specific .h/.c files are made so the code still compiles. A separate per-SoC change will be made immediately following, in order to keep individual patch size down.

* ARM: tegra: make all I2C ports open-drainStephen Warren2014-03-26-16/+16
| | | | | | | | | | | I2C protocol requires open-drain IOs. Fix the Dalmore and Venice2 pinmux tables to configure the IOs correctly. Without this, Tegra may actively drive the lines high while an external device is actively driving the lines low, which can only lead to bad things.

* venice2: move device tree to fix build errorMasahiro Yamada2014-02-20-84/+0
| | | | | | | | | | | | | | | Commit 5ab502cb gathered all device tree sources to arch/$(ARCH)/dts/. So tegra124-venice2.dts also must go to arch/arm/dts directory to build venice2 board. (Commit 5ab502cb had been posted before venice2 board support was merged. So an unvisible conflict happened.)

* dts: move device tree sources to arch/$(ARCH)/dts/Masahiro Yamada2014-02-19-680/+0
| | | | | | | | | | | | | | | | | Unlike Linux Kernel, U-Boot historically had *.dts files under board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/. I think arch/$(ARCH)/dts dicretory is a better location to store both *.dts and *.dtsi files. For example, before this commit, board/xilinx/dts directory had both Microblaze dts (microblaze-generic.dts) and ARM dts (zynq-*.dts), which are totally unrelated. This commit moves *.dts to arch/$(ARCH)/dts/ directories, allowing us to describe nicely mutiple DTBs generation in the next commit. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* kbuild: change out-of-tree buildMasahiro Yamada2014-02-19-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

| | | | | | | | | | | | | | The pinmux code issues a warning if the caller attempts to disable the lock bit in a pinmux register, since this is impossible (once it's locked, the only way to unlock it is to reset the device/pmt controller). The I2C/DDC/CEC/USB macros expect a lock setting to be passed in, and the previous setting of DISABLE caused the pinmux table parsing code to issue the warning.

| | | | | | | | | | | | | | | | | | | | | | Add driver for tegra SPI "SLINK" style driver. This controller is similar to the tegra20 SPI "SFLASH" controller. The difference is that the SLINK controller is a genernal purpose SPI controller and the SFLASH controller is special purpose and can only talk to FLASH devices. In addition there are potentially many instances of an SLINK controller on tegra and only a single instance of SFLASH. Tegra20 is currently ths only version of tegra that instantiates an SFLASH controller. This driver supports basic PIO mode of operation and is configurable (CONFIG_OF_CONTROL) to be driven off devicetree bindings. Up to 4 devices per controller may be attached, although typically only a single chip select line is exposed from tegra per controller so in reality this is usually limited to 1.
