* Davinci: iotable based ioremap() interceptionCyril Chemparathy2010-05-131-2/+2
| | | | | | | | | | | | | | 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: pinmux - use ioremap()Cyril Chemparathy2010-05-131-2/+1

* Davinci: aintc/cpintc - use ioremap()Cyril Chemparathy2010-05-131-1/+1
| | | | | | | | | | | | | | | | | | This patch implements the following: - interrupt initialization uses ioremap() instead of passing a virtual address via davinci_soc_info. - machine definitions directly point to cp_intc_init() or davinci_irq_init() - davinci_intc_type and davinci_intc_base now get initialized in controller specific init functions instead of davinci_common_init() - minor fix in davinci_irq_init() to use intc_irq_num instead of DAVINCI_N_AINTC_IRQ Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

* Davinci: timer - use ioremap()Cyril Chemparathy2010-05-131-4/+4
| | | | | | | | This patch eliminates IO_ADDRESS() usage for Davinci timer definitions. The timer code has correspondingly been modified to ioremap() MMRs instead. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* Davinci: jtag_id - use ioremap()Cyril Chemparathy2010-05-131-2/+1
| | | | | | | | | | | This patch replaces the jtag id base info in davinci_soc_info with a physical address which is then ioremap()ed within common code. This patch (in combination with a similar change for PSC) will allow us to eliminate the SYSCFG nastiness in DA8xx code.

* 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.

* Davinci: gpio - controller type supportCyril Chemparathy2010-05-061-0/+2
| | | | | | | | | | | | | This patch allows for gpio controllers that deviate from those found on traditional davinci socs. davinci_soc_info has an added field to indicate the soc-specific gpio controller type. The gpio initialization code then bails out if necessary. More elements (tnetv107x) to be added later into enum davinci_gpio_type.

| | | | | | | | | | | | | | | | | | This patch adds support for registering for suspend-to-RAM functionality on da850/omap-l138 SoCs. da850 supports wakeup based on external event and RTC alarm.

* davinci: da850/omap-l138: unlock PLL registers during initSekhar Nori2010-02-041-6/+13
| | | | | | | | | | | | | | | | | On omap-l1 devices the PLL registers can be locked from writes. Currently the cpufreq rate setting code unlocks PLL0 before the write actually happens. With suspend support getting added PLL1 registers need be be unlocked as well. To facilitate this, unlock both PLLs during the init time itself. This also obviates the need to unlock PLL registers for each CPUFreq transtition. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

* davinci: DA850/OMAP-L138: avoid using separate initcall for initializing ↵Sekhar Nori2009-11-251-33/+31
| | | | | | | | | | | | | | | | | | 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. Define a platform specific init call which in case of DA850 gets used for initializing the regulator. On other future platforms it can be used for other purposes.

* davinci: RMII support for DA850/OMAP-L138 EVMChaithrika U S2009-11-251-0/+17
| | | | | | | | | | | | | | | | 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>

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.

| | | | | | | | | | | The patch allows Async3 clock source to be selected between PLL1 SYSCLK2 and PLL0 SYSCLK2.
