2012-03-29tegra: i2c: Add I2C driverYen Lin
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.

2012-03-29tegra: usb: Add support for Tegra USB peripheralSimon Glass
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 <linux@bohmer.net> Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

2012-03-29net: fec_mxc: allow use with cache enabledEric Nelson
Ensure that transmit and receive buffers are cache-line aligned. Invalidate cache for each packet as received, update receive buffer descriptors one cache line at a time, flush cache before transmitting.

2012-03-27twl4030: fix potential power supply handling issuesGrazvydas Ignotas
twl4030_pmrecv_vsel_cfg currently first sets up device group (effectively enabling the supply), and only then sets vsel (selects voltage). This could lead to wrong voltage for a short time, or even long time if second i2c write fails. Fix this by writing vsel first and device group after that. Also introduce error checking to not enable the supply if we failed to set the voltage, and start logging errors as power supply problems are usually important.

2012-03-18net/miiphy/serial: drop duplicate "NAMESIZE" defineMike Frysinger
A few subsystems are using the same define "NAMESIZE". This has been working so far because they define it to the same number. However, I want to change the size of eth_device's NAMESIZE, so rather than tweak the define names, simply drop references to it. Almost no one does, and the handful that do can easily be changed to a sizeof(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Fixing build regressions for the Integrator I get find that a few boards try to work around the missing declaration of pciauto_config_init() by declaring it in the local scope. This does not make sense when the sibling functions are in <pci.h> so move the function to the header, ridding the build error in the Integrator and getting rid of the local declarations here and there.

Freescale IFC NAND Machine calculates ECC on 512byte sector and same is used in fsl_ifc_run_command() during ECC status verification. Also this sector is passed to is_blank() for blank checking. It is wrong at first place because is_blank()'s implementation checks for Page size and OOB area size. is_blank() should be called per page for main and OOB area verification.

This reverts commit 4fee6c2f295f932b8febdc7ce8731ba045695fa5. It breaks boards that currently rely on soft-ecc, as pointed out here: http://patchwork.ozlabs.org/patch/140872/ The reverted patch should be resubmitted with documentation, and with the CONFIG_MTD_ECC_SOFT selected from every board that needs it. We could start by looking at what NAND driver the board selects, and whether that driver ever asks for soft ECC. Signed-off-by: Scott Wood <scottwood@freescale.com>
