* aspeed: Add basic ast2500-specific drivers and configurationmaxims@google.com2017-01-28-0/+274
| | | | | | | | | | | | | | | | | | | | | Clock Driver This driver is ast2500-specific and is not compatible with earlier versions of this chip. The differences are not that big, but they are in somewhat random places, so making it compatible with ast2400 is not worth the effort at the moment. SDRAM MC driver The driver is very ast2500-specific and is completely incompatible with previous versions of the chip. The memory controller is very poorly documented by Aspeed in the datasheet, with any mention of the whole range of registers missing. The initialization procedure has been basically taken from Aspeed SDK, where it is implemented in assembly. Here it is rewritten in C, with very limited understanding of what exactly it is doing.

* aspeed: Add drivers common to all Aspeed SoCsmaxims@google.com2017-01-28-0/+166
| | | | | | | | | | | | | | | | | Add support for Watchdog Timer, which is compatible with AST2400 and AST2500 watchdogs. There is no uclass for Watchdog yet, so the driver does not follow the driver model. It also uses fixed clock, so no clock driver is needed. Add support for timer for Aspeed ast2400/ast2500 devices. The driver actually controls several devices, but because all devices share the same Control Register, it is somewhat difficult to completely decouple them. Since only one timer is needed at the moment, this should be OK. The timer uses fixed clock, so does not rely on a clock driver. Add sysreset driver, which uses watchdog timer to do resets and particular watchdog device to use is hardcoded (0) Reviewed-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver implementes platform specific code for the Xenon SDHCI controller which is integrated in the Marvell MVEBU Armada 37xx and Armada 7k / 8K SoCs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some SDHCI drivers might need to do some special controller configuration after the common clock set_ios() function has been called (speed / width configuration). This patch adds a call to the newly created function set_ios_port() when its configured in the host driver. This will be used by the Xenon SDHCI controller driver used on the Marvell Armada 3700 and 7k/8k ARM64 SoCs.

| * mmc: sdhci: Clear SDHCI_CLOCK_CONTROL before configuring the new valueStefan Roese2017-01-25-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch completely clears the SDHCI_CLOCK_CONTROL register before the new value is configured instead of just clearing the 2 bits SDHCI_CLOCK_CARD_EN and SDHCI_CLOCK_INT_EN. Without this change, some clock configurations will lead to the "Internal clock never stabilised." error message on the Xenon SDHCI controller used on the Marvell Armada 3700 and 7k/8k ARM64 SoCs. The Linux SDHCI core driver also writes 0 to this register before the new value is configured. So this patch simplifies the driver a bit and brings the U-Boot driver more in-line with the Linux one.

Since the above patch, you have to setup the fcr register. For board/archs which enable OF_PLATDATA, the new field fcr in struct ns16550_platdata is not filled with a default value ... This leads in not setting up the uarts fifo, which ends in problems, when you send long commands to u-boots commandline. Detected this issue with automated tbot tests on am335x based shc board. The error does not popup, if you type commands.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revision 1.0 of this IP has a quirk where if during a long read transfer the transfer_size register will go to 0, the master will send a NACK to the slave prematurely. The way to work around this is to reprogram the transfer_size register mid-transfer when the only the receive fifo is known full, i.e. the I2C bus is known non-active. The workaround is based on the implementation in the linux-kernel.
