2010-12-07OMAP: GPIO: Implement GPIO as a platform deviceVaradarajan, Charulatha
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.

2010-10-08OMAP: control: move plat-omap/control.h to mach-omap2/control.hPaul Walmsley
Only OMAP2+ platforms have the System Control Module (SCM) IP block. In the past, we've kept the SCM header file in plat-omap. This has led to abuse - device drivers including it; includes being added that create implicit dependencies on OMAP2+ builds; etc. In response, move the SCM headers into mach-omap2/. As part of this, remove the direct SCM access from the OMAP UDC driver. It was clearly broken. The UDC code needs an indepth review for use on OMAP2+ chips.

2009-09-03OMAP2/3 board-*.c files: read bootloader configuration earlierPaul Walmsley
Most board-*.c files read configuration data from the bootloader in their .init_machine() function. This needs to happen earlier, at some point before omap2_init_common_hw() is called. This is because a future patch will use the bootloader serial console port information to enable the UART clocks earlier, immediately after omap2_clk_init(). This is in turn necessary since otherwise clock tree usecounts on clocks like dpll4_m2x2_ck will be bogus, which can cause the currently-active console UART clock to be disabled during boot.

2009-02-08[ARM] OMAP2 SDRC: add SDRAM timing parameter infrastructurePaul Walmsley
For a given SDRAM clock rate, SDRAM chips require memory controllers to use a specific set of timing minimums and maximums to transfer data reliably. These parameters can be different for different memory chips and can also potentially vary by board. This patch adds the infrastructure for board-*.c files to pass this timing data to the SDRAM controller init function. The timing data is specified in an 'omap_sdrc_params' structure, in terms of SDRC controller register values. An array of these structs, one per SDRC target clock rate, is passed by the board-*.c file to omap2_init_common_hw(). This patch does not define the values for different memory chips, nor does it use the values for anything; those will come in subsequent patches. linux-omap source commit is bc84ecfc795c2d1c5cda8da4127cf972f488a696.
