* davinci: da850: add support for SATA interfaceSekhar Nori2011-07-081-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for SATA controller on the DA850/OMAP-L138/AM18x devices. The patch adds the necessary clocks, platform resources and a routine to initialize the SATA controller. The PHY configuration in this patch is courtesy the work done by Zegeye Alemu, Swaminathan and Mansoor Ahamed from TI. While testing this patch, enable port multiplier support iff you are actually using one. The reasons of this behaviour are discussed here: http://patchwork.ozlabs.org/patch/78163/ ChangeLog: v3: Removed fields which were being initialized to zero in PHY configuration. Moved SATA base address definition to the top of the file to make it inline with what is done for the rest of the modules. v2: Addressed comments from Sergei. Removed unnecessary braces and removed unnecessary else after goto. Signed-off-by: Sekhar Nori <nsekhar@ti.com>

* davinci: am18x/da850/omap-l138: add support for higher speed gradesSekhar Nori2010-12-221-15/+60
| | | | | | | | | | | | | | | | | | | | | | | 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>

* davinci: cpufreq: bailout on regulator errorsSekhar Nori2010-09-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | Current cpufreq code does not consider errors that can occur while changing voltage. Code to increase CPU frequency goes ahead even in the case the regulator has failed to increase the voltage. This leads to hard error since lower voltages cannot support increased frequency. Prevent this by not increasing frequency in case increasing voltage is not successful. Also, do not lower the voltage if changing the cpu frequency has failed for some reason. Note that we do not return error on failure to decrease voltage as that is not a hard error. Build fix for non-cpufreq kernels by Caglar Akyuz.

| | | | | | | | | | | | | | This patch allows for a more flexible ioremap() interception based on iotable contents. With this patch, the ioremap() interception code can properly translate addresses only after davinci_soc_info has been initialized. Consequently, in soc-specific init functions, davinci_common_init() has to happen before any ioremap() attempts. The da8xx init sequence has been suitably modified to meet this restriction.

* Davinci: watchdog reset separation across socsCyril Chemparathy2010-05-061-0/+1
| | | | | | | | | | | | | | | | | The earlier watchdog reset mechanism had a couple of limitations. First, it embedded a reference to "davinci_wdt_device" inside common code. This forced all derived platforms (da8xx and tnetv107x) to define such a device. This also would have caused problems in including multiple socs in a single build due to symbol redefinition. With this patch, davinci_watchdog_reset() now takes the platform device as an argument. The davinci_soc_info struct has been extended to include a reset function and a watchdog platform_device. arch_reset() then uses these elements to reset the system in a SoC specific fashion.

| | | | | | | | | | | | | | | | | | regulator Using a device_initcall() for initializing the voltage regulator on DA850 is not such a good idea because it gets called for all platforms - even those who do not have a regulator implemented. This leads to a big fat warning message during boot-up when regulator cannot be found. Instead, tie initialization of voltage regulator to cpufreq init.

| | | | | | | | | | | | | | | | DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY is enabled by proper programming of the IO Expander (TCA6416) ports. Also for RMII PHY to work, the MDIO clock of MII PHY has to be disabled since both the PHYs have the same address. This is done via the GPIO2[6] pin. This patch adds support for RMII PHY. This patch also adds a menuconfig option to select one or no peripheral connected to expander. Currently, sub-options in this menu are RMII and no peripheral.This menuconfig option is similar to the one present for UI card on DA830/OMAP-L137 EVM.

* davinci: DA850/OMAP-L138: add frequency scaling supportSekhar Nori2009-11-251-0/+153
| | | | | | | | | | | | | | | | | | | | | | | | Adds basic frequency scaling support for DA850/OMAP-L138. Currently, frequency scaling only on PLL0 is supported. No scaling of PLL1 as yet. Peripherals like MMC/SD which have a clock input synchronous with ARM clock will not work well since the clock will change behind their backs. Support for notification to such devices to adjust themselves to the new frequency will be added in later patches. Current defconfigs keep CPUFreq disabled so it will not affect normal operation. The OPP defintions assume clock input of 24MHz to the SoC. This is inline with hardcoding of input frequency in the <soc>.c files. At some point this will need to move into board dependent code as new boards appear with a different reference clock. Tested on OMAP-L138 EVM with ondemand governer and a shell script to vary processor load. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* davinci: Correct the GPIO number for LCD panel powerSudhakar Rajashekhara2009-11-251-7/+6
| | | | | | | | | | | | | | | On the latest DA850/OMAP-L138 EVM (Beta) the GPIO pin number of LCD panel power has changed. This patch takes care of this change. Software will support only Beta versions of DA850/OMAP-L138 EVM. In the process, add the missing entry for data pin 0 and remove the GPIO specific pins from da850_lcdcntl_pins structure. EVM specific muxing for LCD is being done in the board file now. Signed-off-by: Sudhakar Rajashekhara <sudhakar.raj@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* davinci: DA850/OMAP-L138: allow async3 source to be changedSekhar Nori2009-11-251-0/+40
| | | | | | | | | | | The patch allows Async3 clock source to be selected between PLL1 SYSCLK2 and PLL0 SYSCLK2. Having Async3 source from PLL1 SYSCLK2 allows peripherals on that domain to remain unaffected by frequency scaling on PLL0.
