* omap: overo: Disable pull-ups on camera PCLK, HS and VS signalsSteve Sakoman2011-10-27-3/+3
| | | | | | | | | | | | | The level shifters used on the Caspa camera module have a 4k output impedance. Combined with the 100uA pull-up resistors in the OMAP3, this raises the ground level to 400mV. Adding crosstalk between the pixel clock and the HS/VS signals on the flat cable (a ground line in between would have been nice), logic 0 levels can raise up to 650mV. This exceeds the camera input pins VIL maximum voltage. This change suggested-by Laurent Pinchart Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* omap: overo: Configure mux for gpio10Steve Sakoman2011-10-27-1/+1
| | | | | | | | | | This pad was previously configured for sysclkout_1. This patch changes the configuration to gpio_10 to reduce radiated noise from the 26Mhz clock, as well as make the pin more generally useful.

* overo: Set IEN on GPMC_CLK to support synchronous clocking.Philip Balister2011-09-30-1/+1
| | | | | | | | Without this change CS's configured for synchronous clocking cannot read data. Signed-off-by: Philip Balister <philip@opensdr.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* OMAP3: Overo: Update GPMC timing for ethernet chipPhilip Balister2011-09-30-9/+0
| | | | | | | | | | The existing timing does not quite meet the minimum requirements in the LAN9221 datasheet. The timing in this patch solves problems noticed on some parts. The patch also combines the CS configuration for the overo and igep0020 boards per request. Signed-off-by: Philip Balister <philip@opensdr.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* ARMV7: OMAP3: Add expansion board detection for OveroSteve Sakoman2010-11-04-0/+4
| | | | | | | | | | Overo expansion boards contain an i2c eeprom to identify themselves. This patch adds code to read and parse the eeprom contents. It prints the expansion board name and revision and modifies environment variables as appropriate. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* ARMV7: OMAP: Overo: Autodetect presence/absence of transceiver on mmc2Steve Sakoman2010-09-08-2/+33
| | | | | | | | | | An upcoming version of Overo uses a Wifi/BT module with 1.8V signaling, eliminating the need for an external transceiver to handle the level shifting. This patch detects whether an external transceiver is present and adjusts the pinmux settings as appropriate.

* ARMV7: OMAP: Configure Overo's second network chipSteve Sakoman2010-09-08-1/+1
| | | | | | | | | Confiures GPMC timings for both chips and also configures pinmux for GPIO_65, which is used as the interrupt signal for the second chip Signed-off-by: Scott Ellis <scott@jumpnowtek.com> Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* ARMV7: OMAP: Add board revision detection for OveroSteve Sakoman2010-09-08-3/+3
| | | | | | | | | | | The latest Overo COM modules encode their revision number on GPIOs 115, 113, and 112. All boards to date have no pullups on these pins and hence appear as revision 0. This patch reads and prints the revision information. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* ARMV7: OMAP: Enable input driver on Overo's MMC1_CLK and MMC3_CLK pinmux setupSteve Sakoman2010-09-08-2/+2
| | | | | | | | This patch modifies the pinmux setup for MMC1_CLK and MMC3_CLK to enable the input driver. MMC2_CLK was already properly configured. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* Overo GPMC registersScott Ellis2010-02-12-0/+9
| | | | | | | | | Use appropriate GPMC timings for the LAN9221 controller on the Gumstix Overo expansion boards not the values in arch-omap3/mem.h which are for a different ethernet controller. Signed-off-by: Scott Ellis <scott@jumpnowtek.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* TI: OMAP3: Overo Tobi ethernet supportOlof Johansson2009-10-13-31/+32
| | | | | | | | | | | | | Add setup for ethernet on Tobi, allowing kernel/ramdisk to be loaded over tftp. This also refactors the smc911x driver to allow for detecting when the chip is missing. I.e. the detect_chip() function is called earlier and will abort gracefully when the Chip ID read returns all 1's.

* OMAP3: Clean up whitespace in mux configsOlof Johansson2009-10-13-322/+322
| | | | | | | | | | | Switch from space-based indentation to tab-based in mux configs, as pointed out by WD at: http://lists.denx.de/pipermail/u-boot/2009-September/061241.html Nothing but whitespace changes in this patch (diff -w gives no output). Signed-off-by: Olof Johansson <olof@lixom.net>
