2015-06-09tegra: clock: Support enabling external clocksSimon Glass
Add a simple function to enable external clocks. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2015-06-09tegra: spi: Support slow SPI ratesSimon Glass
Use the oscillator as the source clock when we cannot achieve a low-enough speed with the peripheral clock. This happens when we request 3MHz on a SPI clock, for example. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2015-06-09dm: tegra: cros_ec: Enable Chrome OS EC on Nyan-bigSimon Glass
Enable the EC and keyboard, using the SPI bus. The EC driver requires a particular format and a deactivation delay. Also U-Boot does not support interrupts. For now, adjust the device tree to comply. At some point we should tidy this up to support interrupts and make tegra and exynos use the same setup. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2015-06-09tegra: spi: Drop the claim_bus() method to correct delaysSimon Glass
At present the driver does not properly honour the requested SPI CS deactivation delay since the SPI bus is changed in the claim_bus() method. Everything the claim_bus() method does can be done when the device is probed (setting the speed and mode) and at the start of a new transfer (where the fifo_status is already cleared). So drop this method. Also, until the delay is complete, we should not touch the bus, so make sure that spi_cs_activate() is called before other things are done in the xfer() method.

2015-06-08pepper: Implement Board Detection mechanismAdam YH Lee
AM335x-based 'Gumstix Pepper' SBCs and variants use different types of RAM (DDR2 vs DDR3 with DDR3 being the default). Detect the board type by reading the factory-programmed EEPROM [1] and use this to select any runtime boot options such as RAM type.

2015-06-08autoboot.c: Remove CONFIG_AUTOBOOT_STOP_STR2 and CONFIG_AUTOBOOT_DELAY_STR2Stefan Roese
These defines for a 2nd autoboot stop and delay string are nearly unused. Only sc3 defines CONFIG_AUTOBOOT_DELAY_STR2. And a patch to remove this most likely unmaintained board is also posted to the list. By removing these defines the code will become cleaner and moving the remaining compile options to Kconfig will get easier.

2015-06-08Kconfig: Enable usage of escape char '\' in string valuesStefan Roese
I might have missed something, but I failed to use the escape char '\' in strings. To pass a printf format string like "foo %d bar\n" via Kconfig to the code. Right now its not possible to use the escape character '\' in Kconfig string values correctly to e.g. set this string value "test output\n". The '\n' will be converted to 'n'. The current implementation removes some of the '\' chars from the input string in conf_set_sym_val(). Examples: '\' -> '' '\\' -> '\' '\\\' -> '\' '\\\\' -> '\\' ... And then doubles the backslash chars in the output string in sym_escape_string_value(). Example: '\' -> '' -> '' '\\' -> '\' -> '\\' '\\\' -> '\' -> '\\' '\\\\' -> '\\' -> '\\\\' ... As you see in these examples, its impossible to generate a single '\' charater in the output string as its needed for something like '\n'. This patch now changes this behavior to not drop some backslashes in conf_set_sym_val() and to not add new backslashes in the resulting output string. Removing the function sym_escape_string_value() completely as its not needed anymore.

2015-06-08mx6_common: Fix LOADADDR and SYS_TEXT_BASE for MX6SL and MX6SXFabio Estevam
Commit 8183058188cd2d942 ("imx6: centralise common boot options in mx6_common.h") broke boot on mx6sl and mx6sx by assuming that all mx6 SoCs use the same LOADADDR/SYS_TEXT_BASE range, which is not correct. DDR on mx6sx/mx6sl starts at 0x80000000. Adjust LOADADDR/SYS_TEXT_BASE to the proper values for mx6sx/mx6sl, so that these SoCs can boot again. Also, TQMA6 requires a custom CONFIG_SYS_TEXT_BASE value, so move its setting prior to the inclusion of mx6_common.h. Signed-off-by: Fabio Estevam <fabio.estevam at freescale.com>

2015-06-05fdt: Pass the device serial number through devicetreePaul Kocialkowski
Before device-tree, the device serial number used to be passed to the kernel using ATAGs (on ARM). This is now deprecated and all the handover to the kernel should now be done using device-tree. Thus, this passes the serial-number property to the kernel using the serial-number property of the root node, as expected by the kernel. The serial number is a string that somewhat represents the device's serial number. It might come from some form of storage (e.g. an eeprom) and be programmed at factory-time by the manufacturer or come from identification bits available in e.g. the SoC.

2015-06-04sunxi: usb_phy: Swap check for disconnect thresholdHans de Goede
Before this commit the code for determining the disconnect threshold was checking for sun4i or sun6i assuming that those where the exception and that newer SoCs use a disconnect threshold of 2 like sun7i does. But it turns out that newer SoCs actually use a disconnect threshold of 3 and sun5i and sun7i are the exceptions, so check for those instead. Here are the settings from the various Allwinner SDK sources: sun4i-a10: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun5i-a13: USBC_Phy_Write(usbc_no, 0x2a, 2, 2); sun6i-a31: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun7i-a20: USBC_Phy_Write(usbc_no, 0x2a, 2, 2); sun8i-a23: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun8i-h3: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun9i-a80: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); Note this commit makes no functional changes for sun4i - sun7i, and changes the disconnect threshold for sun8i to match what Allwinner uses.
