tegra: i2c: Add I2C driver

2012-03-29T06:12:50Z

Add basic i2c driver for Tegra2 with 8- and 16-bit address support. The driver requires CONFIG_OF_CONTROL to obtain its configuration from the device tree.

tegra: Enhance clock support to handle 16-bit clock divisors

2012-03-29T06:12:50Z

I2C ports have a 16-bit clock divisor. Add code to handle this special case so that I2C speeds below 150KHz are supported. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra: Rename NV_PA_PMC_BASE to TEGRA2_PMC_BASE

2012-03-29T06:12:49Z

Change this name to fit with the current convention in the Tegra header file. Signed-off-by: Simon Glass Acked-by: Stephen Warren Signed-off-by: Tom Warren

tegra: usb: Add support for Tegra USB peripheral

2012-03-29T06:12:48Z

This adds basic support for the Tegra2 USB controller. Board files should call board_usb_init() to set things up. Configuration is performed through the FDT, with aliases used to set the order of the ports, like this fragment: aliases { /* This defines the order of our USB ports */ usb0 = "/usb@0xc5008000"; usb1 = "/usb@0xc5000000"; }; drivers/usb/host files ONLY: Acked-by: Remy Bohmer Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra: fdt: Add function to return peripheral/clock ID

2012-03-29T06:12:48Z

A common requirement is to find the clock ID for a peripheral. This is the second cell of the 'clocks' property (the first being the phandle itself). Signed-off-by: Simon Glass Acked-by: Stephen Warren Signed-off-by: Tom Warren

tegra: Add SDMMC support to funcmux

2012-02-12T09:11:22Z

This adds support for SDMMC ports to the funcmux. Only one option is supported: FUNCMUXO_SDMMC_8BIT which selects an 8-bit wide SDIO interface where available. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra: Add I2C support to funcmux

2012-02-12T09:11:22Z

Add support to funcmux for selecting I2C functions and programming the pinmux appropriately. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra: Add enum to select from available funcmux configs

2012-02-12T09:11:22Z

We want to give a name to each available funcmux config. For now we just use the pin group names (even through it is verbose) since there seems to be nothing better. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra: Adjust funcmux config test to permit expansion

2012-02-12T09:11:22Z

We want to support config options other than zero, so move the test to the end to allow intermediate code to OK such a config. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra: Add support for UART init in cpu board.c

2011-12-24T09:23:32Z

We add a way of initialising the selected of UARTs prior to relocation. Boards can use the board_init_uart_f() instead of repeating this code themselves. Signed-off-by: Simon Glass Acked-by: Stephen Warren Signed-off-by: Tom Warren
