* dm: i2c: tegra: Convert to driver modelSimon Glass2014-12-11-374/+210
| | | | | | | | | | | | | | | | | | | | | | This converts all Tegra boards over to use driver model for I2C. The driver is adjusted to use driver model and the following obsolete CONFIGs are removed: - CONFIG_SYS_I2C_INIT_BOARD - CONFIG_I2C_MULTI_BUS - CONFIG_SYS_MAX_I2C_BUS - CONFIG_SYS_I2C_SPEED - CONFIG_SYS_I2C This has been tested on: - trimslice (no I2C) - beaver - Jetson-TK1 It has not been tested on Tegra 114 as I don't have that board.

* ARM: tegra: Add support for nyan-big boardAllen Martin2014-12-11-1/+814
| | | | | | | | | | | | | | | | | | | Nyan-big is a Tegra124 clamshell board that is very similar to venice2, but it has a different panel, the sdcard cd and wp sense are flipped, and it has a different revision of the AS3722 PMIC. This is the Acer Chromebook 13 CB5-311-T7NN (13.3-inch HD, NVIDIA Tegra K1, 2GB). The display is not currently supported, so it should boot on other nyan-based Chromebooks also, but only the device tree for nyan-big is provided here. The device tree file is from Linux but with features removed which are unlikely to be supported in U-Boot soon (regulators, pinmux). Also the addresses are updated to 32-bit.

| | | | | | | | | | Sync this up with Linux v3.18-rc5. Exclude features that are unlikely to supported in U-Boot soon (regulators, pinmux). Also the addresses are updated to 32-bit.

| | | | | | | | | | There seem to be a few EEPROM drivers around - perhaps we should have a single standard one?

| | | | | | | | | | | The concept of a 'current bus' is now implemented in the command line rather than in the uclass.

* lib: errno: introduce errno_str(): returns errno related messagePrzemyslaw Marczak2014-12-11-0/+151
| | | | | | | | | | | | | | | | | | | | | | | The functions error's numbers are standarized - but the error messages are not. The errors are often handled with unclear error messages, so why not use an errno standarized messages. Advantages: - This could decrease the binary size. - Appended with a detailed information, the error message will be clear. This commit introduces new function: - const char *errno_to_str(int errno) The functions returns a pointer to the errno corresponding text message: - if errno is null or positive number - a pointer to "Success" message - if errno is negative - a pointer to errno related message Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Reviewed-by: Tom Rini <trini@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The code may goto 'fail' upon error with 'ret' variable set to an error code, but this variable was being overwritten by a final preparation function to restore the HCLK, so success was (in general) returned even after an error was hit previously. With this change, the function may now return success even if the final preparation function fails, but it's probably enough to print a message because (if successful) the real programming of the fuses has already completed.
