* video: Fix cfb_console for 4-bit wide fontMarek Vasut2013-08-10-0/+21
| | | | | | | | | The cfb_console can't handle 4-bit wide font properly, since with 4-bit wide font, all 8 bits are drawn. Unbreak the video_drawchars() function to correctly render 4-bits only on such fonts. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Anatolij Gustschin <agust@denx.de>
* video: Implement continuous screen refresh for SmartLCD into mxsfbMarek Vasut2013-08-09-0/+26
| | | | | | | | | | | | | The LCDIF interface doesn't give us any means to do continuous refresh when driving a SmartLCD. To work this around, we produce a special circular DMA descriptor, which only writes the HW_LCDIF_CTRL0 register and sets the RUN bit.

* video: Add System-Mode configuration hook into mxsfbMarek Vasut2013-08-09-0/+16
| | | | | | | | | | | | | | | | Add hook that allow configuring SmartLCD attached the MXS LCDIF controller operating in System-Mode. This hook can be overriden by a platform-specific SmartLCD programming routine, which writes the SmartLCD specific values into it's registers. Also, this patch makes sure the SYNC signals are off for the SmartLCD case.

* dma: apbh: Add special circular mode for LCDMarek Vasut2013-08-09-0/+22
| | | | | | | | | | | | | | | | | | Add special function that executes a specially crafted circular DMA descriptor. The function doesn't wait for the descriptor to finish the transfer, since the descritor never finishes. This is useful when operating a SmartLCD through the LCDIF interface, as the LCDIF does not give us any means to have continuous refresh of the SmartLCD. Instead, the RUN bit in the LCDIF CTRL register must be triggered manually. This can be worked around by starting an DMA transfer which continuously sets the RUN bit. This function allows starting exactly such transfer.

* i2c: soft: Fix typo in CONFIG_SYS_I2C_SOFT_SPEEDMarek Vasut2013-08-03-4/+4
| | | | | | | | | | | | | | | | In case only the CONFIG_SYS_I2C_SPEED is set in configuration file, the CONFIG_SYS_I2C_SOFT_SPEED is defined as CONFIG_SYS_I2C_SPEED. The CONFIG_SYS_I2C_SOFT_SPEED is then used throughout the driver. Unfortunatelly, due to a typo in the driver, instead of defining CONFIG_SYS_I2C_SOFT_SPEED, an CONFIG_SYS_SOFT_I2C_SPEED was defined and therefore the driver failed to compile. The same applies for CONFIG_SYS_I2C_SOFT_SLAVE , where the swap happens as well. This patch fixes the issue. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Heiko Schocher <hs@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes NFS root problems with Beagle (3530 ES1.0) when used with external USB-ethernet adapter and "USB start" command used within u-boot. Soft resetting the UHH module causes instability issues on all OMAPs so we just avoid it. See OMAP36xx Errata i571: USB host EHCI may stall when entering smart-standby mode i660: USBHOST Configured In Smart-Idle Can Lead To a Deadlock On OMAP4/5, soft-resetting the UHH module can put it into Smart-Idle mode and lead to a deadlock. On OMAP3 this doesn't seem to be the case but still instabilities are observed on beagle (3530 ES1.0) if soft-reset is used. e.g. NFS root failures with Linux kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usb_lowlevel_init() call already fills and passes back struct ehci_ctrl , which readily contains correctly determined address of the port register block address computed from values from controller configuration registers. Leverage this and make use of this value as this makes the code mode universal, but also gets us rid of the CONFIG_USB_REG_BASE configuration option. Moreover, this patch cleans up the usb_gadget_register_driver() call a little by correcting the error handling. Note the usb_lowlevel_init() and mvudc_probe() are now called in reversed order, but this has no impact on the code.

| | | | | | | | | | | | | | | | | | | | | | | | This enables CONFIG_SYS_I2C on Tegra, updating existing boards and the Tegra i2c driver to support this. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Heiko Schocher <hs@denx.de>
| * | tegra: i2c: Add function to know about current busSimon Glass2013-07-23-17/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than using a variable in various places, add a single function, tegra_i2c_get_bus(), which returns a pointer to information about a bus. This will make it easier to move to the new i2c framework. Signed-off-by: Simon Glass <sjg@chromium.org>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | This Patch introduce the new i2c_core file, which holds the I2C core functions, for the rework of the multibus/ multiadapter support. Also adds changes in i2c.h for the new I2C multibus/multiadapter support. This new support can be activated with the CONFIG_SYS_I2C define.
