* omap4: IO settingsAneesh V2011-09-13-25/+62

* omap4: make SDRAM init work for ES1.0 siliconAneesh V2011-09-13-51/+20
| | | | | | | | | | | | SDRAM init was not working on ES1.0 due to a programming error. A pointer that was passed by value to a function was set in function emif_get_device_details(), but the effect wouldn't be seen in the calling function. The issue came out while testing for ES1.0 because ES1.0 doesn't have any SDRAM chips connected to CS1 Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

* omap: gpio: Use generic APISanjeev Premi2011-09-13-31/+82
| | | | | | | | | | | | | | | 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.

* omap3:clock: check cpu_family before enabling clks for IVA & CAMVaibhav Hiremath2011-09-04-4/+10
| | | | | | | | | | | 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.

* omap3:clock: configure GFX clock to 200MHz for AM/DM37xVaibhav Hiremath2011-09-04-1/+1
| | | | | | | | | | | | 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).

* MX: MX35 / MX5: uniform clock command with powerpcStefano Babic2011-09-04-2/+2
| | | | | | | | | | | There was already a command to show the processor clocks for PowerPC (clocks). For i.MX, the "clockinfo" command was introduce.

* ARM: MX51: PLL errata workaroundDavid Jander2011-09-04-0/+38
| | | | | | | | | | | | | 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.

* omap4: automatic sdram detectionAneesh V2011-08-03-0/+238
| | | | | | | | | | | | | | | | | | | | | | | | | 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>
* omap4: calculate EMIF register valuesAneesh V2011-08-03-4/+953
| | | | | | | | | | | | | | 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.

* OMAP[34]: fix broken timerJohn Rigby2011-07-04-3/+4
| | | | | | | | | | | | | | | | | | | | As implemented now the timer used to implement __udelay counts to 0xffffffff and then gets stuck there because the the programmed reload value is 0xffffffff. This value is not only wrong but illegal according to the reference manual. One can reproduce the bug by leaving a board at the u-boot prompt for sometime then issuing a sleep command. The sleep will hang forever. The timer is a count up timer that reloads as it rolls over from 0xffffffff so the correct load value is 0. Change TIMER_LOAD_VAL from 0xffffffff to 0 and introduce a new constant called TIMER_OVERFLOW_VAL set to 0xffffffff.
