ARM: dts: Add basic support for zoom3 I've tested serial, MMC, smsc911x and wl12xx on zoom3. As my omap is an early ES revision, I have not been able to test off-idle on this one. But anyways, I'd say we have enough device tree support for the zoom to be able to drop the board-zoom files. Patches are welcome to add further features to this .dts file.

ARM: dts: Fix wrong GPMC size mappings for omaps The GPMC binding is obviously very confusing as the values are all over the place. People seem to confuse the GPMC partition size for the chip select, and the device IO size within the GPMC partition easily. The ranges entry contains the GPMC partition size. And the reg entry contains the size of the IO registers of the device connected to the GPMC. Let's fix the issue according to the following table: Device GPMC partition size Device IO size connected in the ranges entry in the reg entry NAND 0x01000000 (16MB) 4 16550 0x01000000 (16MB) 8 smc91x 0x01000000 (16MB) 0xf smc911x 0x01000000 (16MB) 0xff OneNAND 0x01000000 (16MB) 0x20000 (128KB) 16MB NOR 0x01000000 (16MB) 0x01000000 (16MB) 32MB NOR 0x02000000 (32MB) 0x02000000 (32MB) 64MB NOR 0x04000000 (64MB) 0x04000000 (64MB) 128MB NOR 0x08000000 (128MB) 0x08000000 (128MB) 256MB NOR 0x10000000 (256MB) 0x10000000 (256MB) Let's also add comments to the fixed entries while at it.

ARM: OMAP2+: Fix GPMC and simplify bootloader timings for 8250 and smc91x Commit f2bf0e72d000 (ARM: OMAP2+: Add minimal 8250 support for GPMC) added support for using bootloader timings for some devices. Turns out we can do the same by looking at the compatible flags of the child without adding a new function as smc91x has a similar issue as 8250 with the bootloader timings. And let's fix the 8250 naming, we should use the device type as the name like uart instead of 8250 for zoom dts file.

ARM: dts: Add GPMC timings for omap zoom serial port The four port serial port on the zoom debug board uses a TL16CP754C with a single interrupt and GPMC chip select. The serial ports each use a 8 bytes for IO registers, and are 256 bytes apart on the GPMC line. Let's add timings for all four ports so we can remove the GPMC workarounds for using bootloader timings. Not caused by this patch, but looks like u-boot only properly initializes the fifo on the first serial port. Currently the other ports produce garbage at least with my version of u-boot. I suspect that TL16CP754C needs non-standard initialization added to 8250 driver to properly fix this issue. Cc: Roger Quadros <rogerq@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
