2010-12-22davinci: am18x/da850/omap-l138 evm: add support for higher speed gradesSekhar Nori
Apart from the regular AM18x/DA850/OMAP-L138 SoC operating at 300MHz, these SoCs have variants that can operate at a maximum of 456MHz. Variants at 408Mhz and 375 Mhz are available as well. Not all silicon is qualified to run at higher speeds and unfortunately the maximum speed the chip can support can only be determined from the label on the package (not software readable). The EVM hardware for all these variants is the same (except for the actual SoC populated). U-Boot on the EVM sets up ATAG_REVISION to inform the OS regarding the speed grade supported by the silicon. We use this information to pass on the speed grade information to the SoC code. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-12-22davinci: am18x/da850/omap-l138: add support for higher speed gradesSekhar Nori
AM18x/DA850/OMAP-L138 SoCs have variants that can operate at a maximum of 456 MHz at 1.3V operating point. Also the 1.2V operating point has a variant that can support a maximum of 375 MHz. This patch adds three new OPPs (456 MHz, 408 MHz and 372 MHz) to the list of DA850 OPPs. Not all silicon is qualified to run at higher speeds and unfortunately the maximum speed the chip can support can only be determined from the label on the package (not software readable). Because of this, we depend on the maximum speed grade information to be provided to us in some board specific way. The board informs the maximum speed grade information by setting the da850_max_speed variable. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

2010-12-22da850-evm: add baseboard GPIO expander buttons, switches and LEDsBen Gardiner
This patch adds a pca953x platform device for the tca6416 found on the evm baseboard. The tca6416 is a GPIO expander, also found on the UI board at a separate I2C address. The pins of the baseboard IO expander are connected to software reset, deep sleep enable, test points, a push button, DIP switches and LEDs. Add support for the push button, DIP switches and LEDs and test points (as free GPIOs). The reset and deep sleep enable connections are reserved by the setup routine so that userspace can't toggle those lines. The existing tca6416-keypad driver was not employed because there was no apararent way to register the LEDs connected to gpio's on the tca6416 while simultaneously registering the tca6416-keypad instance.

2010-12-22da850-evm: extract defines for SEL{A,B,C} pins in UI expanderBen Gardiner
The setup and teardown methods of the UI expander reference the SEL_{A,B,C} pins by 'magic number' in each function. This uses the common enum for their offsets in the expander setup and teardown functions.

2010-12-22da850-evm: add UI Expander pushbuttonsBen Gardiner
This patch adds EV_KEYs for each of the 8 pushbuttons on the UI board via a gpio-key device. The expander is a tca6416; it controls the SEL_{A,B,C} lines which enable and disable the peripherals found on the UI board in addition to the 8 pushbuttons mentioned above. The reason the existing tca6416-keypad driver is not employed is because there was no aparent way to keep the gpio lines used as SEL_{A,B,C} registered while simultaneously registering the pushbuttons as a tca6416-keypad instance. Some experimentation with the polling interval was performed; we were searching for the largest polling interval that did not affect the feel of the responsiveness of the buttons. It is very subjective but 200ms seems to be a good value that accepts firm pushes but rejects very light ones. The key values assigned to the buttons were arbitrarily chosen to be F1-F8.

2010-12-20ARM: pxa: Push Colibri evalboard MFP into module filesMarek Vasut
This change -- pushing the MFP configuration back into Module files -- is necessary because some evalboards can be used with multiple modules, where MFP differs from module to module. Therefore MFP isn't board-specific, but module-specific and the module should preconfigure itself for the board.
