2011-09-13omap: gpio: generic changes after changing APISanjeev Premi
This patch contains the generic changes required after change to generic API in the previous patch. Signed-off-by: Sanjeev Premi <premi@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
2011-09-13omap: gpio: Use generic APISanjeev Premi
Convert all OMAP specific functions to use the common API definitions in include/asm/gpio.h. In the process, made few additional changes: - Use -EINVAL consistently. -1 was used in many places. - Removed one-liner static functions that were used only once. Replaced the content as necessary. - Combines implementation of functions omap_get_gpio_dataout() and omap_get_gpio_datain(). To do so, new static function _get_gpio_direction() was added.

2011-09-04omap3:clock: check cpu_family before enabling clks for IVA & CAMVaibhav Hiremath
In case of AM3517 and AM3505 (which is OMAP3 varients), IVA2 and ISP-CAMERA modules have been removed. So add check for cpu_family before enabling clocks for these modules, else this impacts subsequent power consumption and system suspend/resume functionality.

2011-09-04omap3:clock: configure GFX clock to 200MHz for AM/DM37xVaibhav Hiremath
AM/DM37x is another OMAP3 variant, where the GFX clock has been boosted to 192MHz/200MHz. So fix the GFX_DIV value for this change. HW Errata: Due to dependency of TV out clock of 54MHz, it is not possible to configure GFX to 192MHz. So as per HW errats, the recommended GFX clock is 200MHz (=CORE_CLK/2).

2011-09-04MX: MX35 / MX5: uniform clock command with powerpcStefano Babic
There was already a command to show the processor clocks for PowerPC (clocks). For i.MX, the "clockinfo" command was introduce. The patch sets the same command name used on PowerPC. A nasty and not needed newline is also dropped in the help for the command. Signed-off-by: Stefano Babic <sbabic@denx.de>
2011-09-04ARM: MX51: PLL errata workaroundDavid Jander
This is a port of the official PLL errata workaround from Freescale to mainline u-boot. The PLL's in the i.MX51 processor can go out of lock due to a metastable condition in an analog flip-flop when used at high frequencies. This workaround implements an undocumented feature in the PLL (dither mode), which causes the effect of this failure to be much lower (in terms of frequency deviation), avoiding system failure, or at least decreasing the likelihood of system failure.

2011-09-03integrator: convert to new build systemLinus Walleij
This deletes the integrator split_by_variant.sh script and defines a number of unique board types for the core modules that are meaningful to support for the Integrator AP/CP, i.e. the ones that did not just say "unsupported core module" in split_by_variant.sh. If more core modules need to be supported they are easy to add. We delete all the old cruft in Makefile and MAKEALL that was working around the old way of building boards. We create a unique config file per board to satisfy the build system, but they are just oneliners that include the existing integratorap.h and integratorcp.h configs.

2011-08-03omap4: automatic sdram detectionAneesh V
Identify SDRAM devices connected to EMIF automatically: LPDDR2 devices have some Mode Registers that provide details about the device such as the type, density, bus width etc. EMIF has the capability to read these registers. If there are no devices connected to a given chip-select reading mode registers will return junk values. After reading as many such registers as possible and matching with expected ranges of values the driver can identify if there is a device connected to the respective CS. If we identify that a device is connected the values read give us complete details about the device. This along with the base AC timings specified by JESD209-2 allows us to do a complete automatic initialization of SDRAM that works on all boards. Please note that the default AC timings specified by JESD209-2 will be safe for all devices but not necessarily optimal. However, for the Elpida devices used on Panda and SDP the default timings are both safe and optimal. Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
2011-08-03omap4: calculate EMIF register valuesAneesh V
Calculate EMIF register values based on AC timing parameters from the SDRAM datasheet and the DDR frequency rather than using the hard-coded values. For a new board the user doen't have to go through the tedious process of calculating the register values. Instead, just provide the AC timings from the device data sheet as input and the driver will automatically calculate the register values.
