Convert omap2_get_clksel to use new struct clksel and struct clksel_rate data. Also fix its parameter order to conform with the rest of the clock framework functions (i.e., struct clk first). Signed-off-by:

Convert omap2_clksel_to_divisor() and omap2_divisor_to_clksel() to use the new struct clksel and struct clksel_rate data. Add omap2_get_clksel_by_parent() utility code, called by both functions, to return the appropriate struct clksel for a given (struct clk, parent struct clk) combination. Signed-off-by:

Source-selectable clksel clocks have a 'default parent' assigned to them at compile-time. This default parent may or may not match the reality that is configured in the hardware registers by the bootloader. Clock tree recalculations could be erratic if the struct clk parent field contents don't match the hardware registers. Resolve this by creating omap2_init_clksel_parent() to read the hardware registers and update the struct clk parent field as appropriate for clksel clocks. Add an '.init' field to each source-selectable clk structure so that the parent is fixed up when the clock is initially registered. (We don't do this for clksel clocks that are only rate-selectable, since they only have one possible parent clock.) Signed-off-by:

Many OMAP2 clocks are either source- or divisor-selectable by twiddling various register bits; these are 'clksel' clocks. The table of rate divisors and source clock settings was previously embedded in the clock.c source code. Encode this data in two data structures: 1) struct clksel_rate for divisor-selection, mapping divisor values to register bit field values, along with a flags field indicating which chips the rate is available for -- one for each parent-rate combination; and: 2) struct clksel for source-selection, mapping parent struct clk pointers to struct clksel_rate array pointers; one for each parent. Also, add several fields to the clk structure: 1) clksel: pointer to the struct clksel array 2) clksel_reg: pointer to the clksel register 3) clksel_mask: mask for the clksel bitfield Add this data to each clksel clock. All this data is not yet used by the clock framework; that functionality is in the following patches. N.B. Two clocks, sys_clkout and sys_clkout2, could not be converted to this setup without splitting source selection and divisor selection. This is because these clocks use separate registers for each selector. So, create two new clocks, sys_clkout_src and sys_clkout2_src, and locate source-selection there, and keep divisor selection in sys_clkout/sys_clkout2. This entailed modifying board-n800-audio.c.

omap2_mpu_recalc() actually just looks up what the MPU speed 'should' currently be from the current virt_prcm_set rate set, rather than reporting the actual hardware settings. Clarify this by renaming it to omap2_table_mpu_recalc() and adding some comments. Signed-off-by:

omap2_propagate_rate() seems completely superfluous. It handles two cases. The first case is for non-fixed rate clocks. It assigns the parent's rate to the clock, and continues propagating the rate downwards. This can be handled by adding a RATE_PROPAGATES clock flag to the clock, if it wasn't there already, and by using followparent_recalc() directly as the recalc function. The second case is for fixed rate clocks. Here all we need to do is to call propagate_rate() directly, so, use that for the recalc function. Signed-off-by:

Add a new clock framework function, recalculate_root_clocks(), that recalculates all root clocks (i.e., clocks with no parent clock). Call this function in omap2_clk_arch_init(), rather than manually propagating specific clocks. Add propagate_rate() recalcs to func_32k_ck and osc_ck. Signed-off-by:

This should be the last of the CamelCase removal for CPPI... more local variable updates: - "txState" --> tx_ram - "bReqComplete" --> complete (or remove) - "bdPtr" --> bd - "chanNum" --> index - remove pointless/unused "numCompleted" - convert cppi_rx_scan() to use bool, return true/false Also improve indentation on the monstrous TX side of cppi_completion(); TX paths still deserve a rewrite to better match the RX side.

Additional cleanup for debug boards on H2/P2/H3/H4: move the init code that's not board-specific into a new file where it can be easily shared between all the different boards (avoiding code duplication, and making it easier to support more devices). Make H4 use that. This should be easy to drop in to the OMAP1 boards using these debug cards; the only difference seems to be that the p2 does an extra reset of the smc using the fpga (probably all boards could do that, if it's necessary) and doesn't use the gpio mux or request APIs.
