2020-12-19dm: Avoid accessing seq directlySimon Glass1-1/+1
At present various drivers etc. access the device's 'seq' member directly. This makes it harder to change the meaning of that member. Change access to go through a function instead. The drivers/i2c/lpc32xx_i2c.c file is left unchanged for now. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-12-14dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass29-117/+113
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass43-58/+58
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

Currently when using OF_PLATDATA the binding between devices and drivers is done trying to match the compatible string in the node with a driver name. However, usually a single driver supports multiple compatible strings which causes that only devices which its compatible string matches a driver name get bound. To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro, which generates no code at all, but allows an easy way to declare driver name aliases.
