The gcc documentation indicates that section attributes should be added to the end of the function declaration: extern void foobar (void) __attribute__ ((section ("bar"))); However gcc seems to be very permissive with where attributes can be placed. clang on the other hand isn't so permissive, and fails if you put the section definition in the middle of the return type: drivers/clk/ti/divider.c:298:28: error: expected ';' after struct static struct clk_div_table ^ ; drivers/clk/ti/divider.c:298:1: warning: 'static' ignored on this declaration [-Wmissing-declarations] static struct clk_div_table ^ drivers/clk/ti/divider.c:299:9: error: type specifier missing, defaults to 'int' [-Werror,-Wimplicit-int] __init *ti_clk_get_div_table(struct device_node *node) ~~~~~~ ^ drivers/clk/ti/divider.c:345:9: warning: incompatible pointer types returning 'struct clk_div_table *' from a function with result type 'int *' [-Wincompatible-pointer-types] return table; ^~~~~ drivers/clk/ti/divider.c:419:9: warning: incompatible pointer types assigning to 'const struct clk_div_table *' from 'int *' [-Wincompatible-pointer-types] *table = ti_clk_get_div_table(node); ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~ 3 warnings and 2 errors generated. By convention, most of the kernel code puts section attributes between the return type and function name. In the case where the return type is a pointer, it's important to place the '*' on left of the __init. This updated code works for both gcc and clang.

| * clk: ti: change clock init to use generic of_clk_initTero Kristo2014-09-291-25/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the TI clock driver initialized all the clocks hierarchically under each separate clock provider node. Now, each clock that requires IO access will instead check their parent node to find out which IO range to use. This patch allows the TI clock driver to use a few new features provided by the generic of_clk_init, and also allows registration of clock nodes outside the clock hierarchy (for example, any external clocks.)

* | clk: ti: set CLK_SET_RATE_NO_REPARENT for ti,mux-clockTomi Valkeinen2014-06-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When setting the rate of a clock, by default the clock framework will change the parent of the clock to the most suitable one in __clk_mux_determine_rate() (most suitable by looking at the clock rate). This is a rather dangerous default, and causes problems on AM43x when using display and ethernet. There are multiple ways to select the clock muxes on AM43x, and some of those clock paths have the same source clocks for display and ethernet. When changing the clock rate for the display subsystem, the clock framework decides to change the display mux from the dedicated display PLL to a shared PLL which is used by the ethernet, and then changes the rate of the shared PLL, breaking the ethernet. As I don't think there ever is a case where we want the clock framework to automatically change the parent clock of a clock mux, this patch sets the CLK_SET_RATE_NO_REPARENT for all ti,mux-clocks.

ATL can be also used to track errors between two reference clocks (BWS, AWS) and generate a modulated clock output which averages to some desired frequency. In essence ATL is generating a clock to be used by an audio codec and also to be used by the SoC as MCLK. To be able to integrate the ATL provided clocks to the clock tree we need two types of DT binding: - DT clock nodes to represent the ATL clocks towards the CCF - binding for the ATL IP itself which is going to handle the hw configuration The reason for this type of setup is that ATL itself is a separate device in the SoC, it has it's own address space and clock domain. Other IPs can use the ATL generated clock as their functional clock (McASPs for example) and external components like audio codecs can also use the very same clock as their MCLK. The ATL IP in DRA7 contains 4 ATL instences. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tero Kristo <t-kristo@ti.com>

| * | clk: ti/divider: fix rate calculation for fractional ratesTomi Valkeinen2014-02-271-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ti/clk-divider.c does not calculate the rates consistently at the moment. As an example, on OMAP3 we have a clock divider with a source clock of 864000000 Hz. With dividers 6, 7 and 8 the theoretical rates are: 6: 144000000 7: 123428571.428571... 8: 108000000 Calling clk_round_rate() with the rate in the first column will give the rate in the second column: 144000000 -> 144000000 143999999 -> 123428571 123428572 -> 123428571 123428571 -> 108000000 Note how clk_round_rate() returns 123428571 for rates from 123428572 to 143999999, which is mathematically correct, but when clk_round_rate() is called with 123428571, the returned value is surprisingly 108000000. This means that the following code works a bit oddly: rate = clk_round_rate(clk, 123428572); clk_set_rate(clk, rate); As clk_set_rate() also does clock rate rounding, the result is that the clock is set to the rate of 108000000, not 123428571 returned by the clk_round_rate. This patch changes the ti/clk-divider.c to use DIV_ROUND_UP when calculating the rate. This gives the following behavior which fixes the inconsistency: 144000000 -> 144000000 143999999 -> 123428572 123428572 -> 123428572 123428571 -> 108000000 Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>

As the rate is configured to zero, this will result in several divisions by zero, and misconfigured timings, with devices on the bus being lost in the La La Land. It is better to remove gpmc_fck from the dummy clocks, so that gpmc.c can fail gracefully.
