| | | | | | | | | | | | | | | | | | | | | | | | Multiple OMAP3/4 boards have a DVI framer output. This patch makes the boards use the new panel-dvi driver, instead of the panel-generic-dpi driver.

|/ | | | | | | | | | | | | | There's no need to call omap2_init_common_devices from init_early. It no longer does anything else except reprogram the memory timings for some boards, so it's better to do it later so we have a chance to get console messages if something goes wrong. Move it to happen after omap_serial_init gets called. And while patching it anyways, rename it to omap_sdrc_init as suggested by Benoit Cousson <b-cousson@ti.com>.

| * omap: Set separate timer init functions to avoid cpu_is_omap testsTony Lindgren2011-06-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is needed for the following patches so we can initialize the rest of the hardware timers later on. As with the init_irq calls, there's no need to do cpu_is_omap calls during the timer init as we only care about the major omap generation. This means that we can initialize the sys_timer with the .timer entries alone. Note that for now we just set stubs for the various sys_timer entries that will get populated in a later patch. The following patches will also remove the omap_dm_timer_init calls and change the init for the rest of the hardware timers to happen with an arch_initcall.

| | | | | | | | | | | | | | | | | | | | | | | | | | This allows us to remove cpu_is_omap calls from init_irq functions. There should not be any need for cpu_is_omap calls as at this point. During the timer init we only care about SoC generation, and not about subrevisions. The main reason for the patch is that we want to initialize only minimal omap specific code from the init_early call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hwmod adaptation design requires each of the DSS HW IP to be a platform driver. So a platform_driver for DSI is created and init exit methods are moved from core.c to its driver probe,remove. pdev member has to be maintained by its own drivers. Also, vdds_dsi regulator handling is copied to dsi.c, since vdds_dsi regulator is needed by dpi_init() too. Board files are updated accordingly to add 2 instances of vdds_dsi regulator. DSI platform driver is registered from inside omap_dss_probe, in the order desired.

| | | | | | | | | | | | | | | | | | | | | Split omap2_init_common_hw() into two functions. The first, omap2_init_common_infrastructure(), initializes the hwmod code and data, the OMAP PM code, and the clock code and data. The second, omap2_init_common_devices(), handles any other early device initialization that, for whatever reason, has not been or cannot be moved to initcalls or early platform devices. This patch is required for the hwmod postsetup patch, which allows board files to change the state that hwmods should be placed into at the conclusion of the hwmod _setup() function. For example, for a board whose creators wish to ensure watchdog coverage across the entire kernel boot process, code to change the watchdog's postsetup state will be added in the board-*.c file between the omap2_init_common_infrastructure() and omap2_init_common_devices() function calls.

This causes the SDIO module to fail being detected. This patch adds the two regulators that actually feed the WLAN module (1v8 from the TWL4030 VIO LDO, and a fixed 3v3). With that patch, the second channel is properly detected. Details of the power supply implementation were kindly provided by Enric Balletbo i Serra.

| * OMAP: GPIO: Implement GPIO as a platform deviceVaradarajan, Charulatha2010-12-071-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement GPIO as a platform device. GPIO APIs are used in machine_init functions. Hence it is required to complete GPIO probe before board_init. Therefore GPIO device register and driver register are implemented as postcore_initcalls. omap_gpio_init() does nothing now and this function would be removed in the next patch as it's usage is spread across most of the board files. Inorder to convert GPIO as platform device, modifications are required in clockxxxx_data.c file for OMAP1 so that device names can be used to obtain clock instead of getting clocks by name/NULL ptr. Use runtime pm APIs (pm_runtime_put*/pm_runtime_get*) for enabling or disabling the clocks, modify sysconfig settings and remove usage of clock FW APIs. Note 1: Converting GPIO driver to use runtime PM APIs is not done as a separate patch because GPIO clock names are different for various OMAPs and are different for some of the banks in the same CPU. This would need usage of cpu_is checks and bank id checks while using clock FW APIs in the gpio driver. Hence while making GPIO a platform driver framework, PM runtime APIs are used directly. Note 2: While implementing GPIO as a platform device, pm runtime APIs are used as mentioned above and modification is not done in gpio's prepare for idle/ resume after idle functions. This would be done in the next patch series and GPIO driver would be made to use dev_pm_ops instead of sysdev_class in that series only. Due to the above, the GPIO driver implicitly relies on CM_AUTOIDLE = 1 on its iclk for power management to work, since the driver never disables its iclk. This would be taken care in the next patch series (see Note 3 below). Refer to http://www.mail-archive.com/linux-omap@vger.kernel.org/msg39112.html for more details. Note 3: only pm_runtime_get_sync is called in gpio's probe() and pm_runtime_put* is never called. This is to make the implementation similar to the existing GPIO code. Another patch series would be sent to correct this. In OMAP3 and OMAP4 gpio's debounce clocks are optional clocks. They are enabled/ disabled whenever required using clock framework APIs TODO: 1. Cleanup the GPIO driver. Use function pointers and register offest pointers instead of using hardcoded values 2. Remove all cpu_is_ checks and OMAP specific macros 3. Remove usage of gpio_bank array so that only instance specific information is used in driver code 4. Rename 'method'/ avoid it's usage 5. Fix the non-wakeup gpios handling for OMAP2430, OMAP3 & OMAP4 6. Modify gpio's prepare for idle/ resume after idle functions to use runtime pm implentation.

| | | | | | | | | | The changes are: - Use 'for' loop instead 'while' loop. - No need to initialize ret to 0, we're assigning it right after. - No need to check for onenandcs < GPMC_CS_NUM here, it will always be true.
