From a4ca9dbe44a167d63545c7ac2b5a36d7b0b415b6 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 22 Aug 2011 23:57:23 -0700 Subject: ARM: OMAP: Move omap2_init_common_devices out of init_early 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 .

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. Thanks to Tony Lindgren for some help with the second revision of this patch.

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.

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.

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.

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.

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.

These ideally should be used by drivers in mach directory. Using a generic hwmod name like "gpu" instead of the actual device name which could change in the future, allows us to: a) Could in effect help replace apis such as omap2_get_mpuss_device, omap2_get_iva_device, omap2_get_l3_device, omap4_get_dsp_device, etc.. b) Scale to more devices rather than be restricted to named functions c) Simplify driver's platform_data from passing additional fields all doing the same thing with different function pointer names just for accessing a different device name.
