This generalizes the omap2_mcbsp1_mux_clkr_src and omap2_mcbsp1_mux_fsr_src implementation between generic McBSP and OMAP2 specific McBSP code. These functions are used to select source for CLKR and FSR signals on OMAP2+. Start generalizing the code by implementing an optional mux_signal function pointer in platform data that will implement the actual muxing and which is called now from omap2_mcbsp1_mux_clkr_src and omap2_mcbsp1_mux_fsr_src. These functions are to be removed later and cleanup the API so that mux_signal gets its arguments directly from client code. Signed-off-by:

This generalizes the omap2_mcbsp_set_clks_src implementation between generic McBSP and OMAP2 specific McBSP code. Currently this function is used to select either internal fclk or clks pin as a McBSP CLKS source on OMAP2+. Implement generalization by having an optional set_clk_src function pointer in platform data that is used to select parent for a given clock. Idea is to pass higher level source clock name (later coming from client driver) that platform specific code will map to platform specific clock name. API cleanup between McBSP and client code comes later. Signed-off-by:

Sidetone resource is already registered for a device so there is no need for cpu_is_omap34xx() and McBSP port number tests in the driver. We can cleanup and make the code generic by dropping remaining CONFIG_ARCH_OMAP3 conditional compilations and then using sidetone resource and st_data variable for runtime tests. Signed-off-by:

Active sidetone requires that McBSP interface clock doesn't idle and there is no mechanism in hwmod to turn autoidling on/off in runtime. McBSP2 and 3 in OMAP34xx share their interface clock with McBSP sidetone module and that interface clock must be active when the sidetone is operating. Sidetone has its own autoidle bit which should keep the interface clock active but it is broken. Putting the McBSP core to no-idle mode when the sidetone is active is no good either since it results to higher power consumption when using the threshold based DMA transfers. For making the McBSP code more generic, move this sidetone clock management with fixme comments to mach-omap2/mcbsp.c and pass pointer to it via platform data. Signed-off-by:

Remove CONFIG_ARCH_OMAP3 conditional compilation and cpu_is_omap34xx test around buffer threshold based transfer and DMA operating mode control. Use instead the buffer_size in platform data to determine when these sysfs controls are exposed and when to access related McBSP registers. Rationale for this is to make code generic and to allow to use it on OMAP4 that also supports threshold based transfers. Currently buffer_size variable is set only for OMAP3 SoCs but it is easy to extend to OMAP4 and any later OMAP version. Signed-off-by:

McBSP transmit and receive configuration control registers must be set up for OMAP2430 and later. Replace is_omap tests in generic code with a new feature flag has_ccr in platform data so that there is no need to change code for any upcoming OMAP version. Signed-off-by:

Currently wakeup control code is compiled only when CONFIG_ARCH_OMAP3 is set even it should be available for CONFIG_ARCH_OMAP4 only builds also. Fix this by making wakeup control generic so that it is executed whenever new feature flag has_wakeup in platform data is set. Currently flag is set for McBSP config types 3 and 4. Remove also old comments about idle mode settings and HW bug workarounds that were not updated during hwmod conversion. Signed-off-by:

Register access can be made more generic by calculating register address offsets runtime from common register definitions and by using reg_size and reg_step variables that are passed via platform data. Common register definitions are possible since McBSP registers are ordered similarly between OMAP versions. Remove also references to OMAP2+ specific config_type variable from generic McBSP code since other variables and feature flags are better to carry needed information from platform code.

During the idle/suspend path, we expect the console lock to be held so that no console output is done during/after the UARTs are idled. However, when using the no_console_suspend argument on the command-line, the console driver does not take the console lock. This allows the possibility of console activity after UARTs have been disabled. To fix, update the current is_suspending() to also check the console_suspend_enabled flag. Reported-by:

Rather than embedding a struct platform_device inside a struct omap_device, decouple them, leaving only a pointer to the platform_device inside the omap_device. Use the arch-specific data field of the platform_device (pdev_archdata) to add an omap_device pointer after the platform_device has been created. Signed-off-by: -

All of the device init and device driver interaction with omap_device is done using platform_device pointers. To make this more explicit, have omap_device return a platform_device pointer instead of an omap_device pointer. All current users of the omap_device pointer were only using it to get at the platform_device pointer or struct device pointer, so fixing all of the users was trivial. This also makes it more difficult for device init code to directly access members of struct omap_device, and allows for easier changing of omap_device internals.

For consistency in kernel printk output for devices, use dev_dbg(), dev_warn(), dev_err() instead of pr_debug(), pr_warning() and pr_err(), some of which currently use direct access of name from platform_device and others of which use dev_name(). Using the dev_* versions uses the standard device naming from the driver core. Some pr_* prints were not converted with this patch since they are used before the platform_device and struct device are created so neither the dev_* prints or dev_name() is valid. Reported-by:

In preparation for OMAP_CHIP() removal, split pwrdm_init() into three functions. This allows some of them to be called multiple times: for example, pwrdm_register_pwrdms() can be called once to register powerdomains that are common to a group of SoCs, and once to register powerdomains that are specific to a single SoC. The appropriate order to call these functions - which is enforced by the code - is: 1. pwrdm_register_platform_funcs() 2. pwrdm_register_pwrdms() (can be called multiple times) 3. pwrdm_complete_init() Convert the OMAP2, 3, and 4 powerdomain init code to use these new functions.

The OMAP3505/AM3505 appears to be based on the same silicon as the OMAP3517/AM3517, with some features disabled via eFuse bits. Follow the same practice as OMAP3430 and identify these devices internally as part of the OMAP3517/AM3517 family. The OMAP3503/3515/3525/3530 chips appear to be based on the same silicon as the OMAP3430, with some features disabled via eFuse bits. Identify these devices internally as part of the OMAP3430 family. Remove the old OMAP35XX_CLASS, which actually covered two very different chip families. The OMAP3503/3515/3525/3530 chips will now be covered by OMAP343X_CLASS, since the silicon appears to be identical. For the OMAP3517/AM3517 family, create a new class, OMAP3517_CLASS.
