* | arm: mvebu: drivers/ddr: Add DDR3 driver with training code from Marvell bin_hdrStefan Roese2015-02-06-0/+15419
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the DDR3 setup and training code taken from the Marvell U-Boot repository. This code used to be included as a binary (bin_hdr) into the AXP boot image. Not linked with the main U-Boot. With this code addition and the following serdes/PHY setup code, the Armada-XP support in mainline U-Boot is finally self-contained. So the complete image for booting can be built from mainline U-Boot. Without any additional external inclusion. Hopefully other MVEBU SoC's will follow here. Support for some SoC's has been removed in this version. This is: MV_MSYS: The code referred to by the MV_MSYS define is currently unused. And its not really planned to support this in mainline. So lets remove it to make the code clearer and increase the readability. MV88F68XX (A38x): The code referred to by the MV88F68XX define (A38x) is currently unused. And its partial and not sufficient for this device in this stage. So lets remove it to make the code clearer and increase the readability. MV88F66XX (ALP): The code referred to by the MV88F66XX define is currently unused. And its not really planned to support this in mainline. So lets remove it to make the code clearer and increase the readability. MV88F78X60_Z1: The code referred to by the MV88F78X60_Z1 define is currently unused. As the Z1 revision of the AXP is not supported in mainline anymore. So lets remove it to make the code clearer and increase the readability. Remove support for Z1 & A0 AXP revisions (steppings). The current stepping is B0 and this is the only one that is actively supported in this code version. Tested on AXP using a SPD DIMM setup on the Marvell DB-MV784MP-GP board and on a custom fixed DDR configuration board (maxbcm). Note: This code has undergone many hours of coding-style cleanup and refactoring. It still is not checkpatch clean though, I'm afraid. As the factoring of the code has so many levels of indentation that many lines are longer than 80 chars. This might be some task to tackly later on.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On both my A13-OLinuxIno and my A13-OLinuxIno-Micro, the vga output gives an unstable image when active low v or hsync is used. The problem seems to be specific to the OLinuxIno A13 (normal & micro) boards. I've just looked up the schematics and they use an opendrain driver for the vga sync lines, and with sync pulses it is the logical high->low edge of the pulse which counts for the timing, which with an active low sync is being driven by the pull-up, and that simply seems to not drive it hard enough to get a stable image. So force v and hsync active high on these boards. independent of what the modeline says. This fixes the unstable image.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a phy driver for the Micrel KSZ8895 switch. As the SoC MAC is directly connected to the switch MAC the link to the switch is always up. But the KSZ8895 switch can be hardwired in three configuration modes : - not configurable with eventually an eeprom-stored configuration - configurable by the mdio/mdc connection (SMI protocol) - configurable by a SPI connection. In not configurable mode, the switch starts automatically, but in the other modes, it must be started programmatically, by writing 1 in configuration register 1. We only support the not configurable and mdio/mdc (aka SMI) modes here.

| * | dm: core: Allow uclasses to specify private data for a device's childrenSimon Glass2015-01-29-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In many cases the per-child private data for a device's children is defined by the uclass rather than the individual driver. For example, a SPI bus needs to store information about each of its children, but all SPI drivers store the same information. It makes sense to allow the uclass to define this data. If the driver provides a size value for its per-child private data, then use it. Failng that, fall back to that provided by the uclass.

| * | dm: core: Add a flag to control sequence numberingSimon Glass2015-01-29-15/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present we try to use the 'reg' property and device tree aliases to give devices a sequence number. The 'reg' property is often actually a memory address, so the sequence numbers thus-obtained are not useful. It would be better if the devices were just sequentially numbered in that case. In fact neither I2C nor SPI use this feature, so drop it. Some devices need us to look up an alias to number them within the uclass. Add a flag to control this, so it is not done unless it is needed. Adjust the tests to test this new behaviour. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
