DRA7 Data Manual (SPRS857L - August 2014) section 4.1.1 states: "All unused power supply balls must be supplied with the voltages specified in the Section 5.2, Recommended Operating Conditions". This implies that all unused voltage rails for Vayu can never be switched off even if the hardware blocks inside that voltage domain is unused. Switching off these unused rails may result in stability issues on other domains and increased leakage and power-on-hour impacts. J6eco-evm dts file already considers this, however j6evm-dts file needs to be fixed to consider this constraint of the SoC. Signed-off-by:

Add MMC1 and 2 nodes. MMC1 is SDcard and MMC2 is eMMC. NOTE on MMC1 card detect: Ideally, we should be using in-built SDCD support, but we dont have it yet. So, use the fact that control module of DRA7 is setup such that no matter what mode one configures it, GPIO option is always hardwired in - use GPIO mode for SDcard detection. [peter.ujfalusi@ti.com] The power line feeding the SD card is also used by other devices on the EVM. Use generic name instead of mmc2_3v3 so when other devices want to use the same regulator it will look a bit better. Signed-off-by:

With the GPMC warnings now enabled, I noticed the LAN9220 timings can overflow the GPMC registers with 200MHz L3 speed. Earlier we were just skipping the bad timings and would continue with the bootloader timings. Now we no longer allow to continue with bad timings as we have the timings in the .dts files. We could start using the GPMC clock divider, but let's instead use the u-boot timings that are known to be working and a bit faster. These are basically the u-boot NET_GPMC_CONFIG[1-6] defines deciphered. Except that we don't set gpmc,burst-length as that's only partially configured and does not seem to work if fully enabled.

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:

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.
