ARM: pxa: fix missing-prototypes warnings The PXA platform has a number of configurations that end up with a warning like these when building with W=1: drivers/hwmon/max1111.c:83:5: error: no previous prototype for 'max1111_read_channel' [-Werror=missing-prototypes] arch/arm/mach-pxa/reset.c:86:6: error: no previous prototype for 'pxa_restart' [-Werror=missing-prototypes] arch/arm/mach-pxa/mfp-pxa2xx.c:254:5: error: no previous prototype for 'keypad_set_wake' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa25x.c:70:14: error: no previous prototype for 'pxa25x_get_clk_frequency_khz' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa25x.c:325:12: error: no previous prototype for 'pxa25x_clocks_init' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa27x.c:74:14: error: no previous prototype for 'pxa27x_get_clk_frequency_khz' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa27x.c:102:6: error: no previous prototype for 'pxa27x_is_ppll_disabled' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa27x.c:470:12: error: no previous prototype for 'pxa27x_clocks_init' [-Werror=missing-prototypes] arch/arm/mach-pxa/pxa27x.c:44:6: error: no previous prototype for 'pxa27x_clear_otgph' [-Werror=missing-prototypes] arch/arm/mach-pxa/pxa27x.c:58:6: error: no previous prototype for 'pxa27x_configure_ac97reset' [-Werror=missing-prototypes] arch/arm/mach-pxa/spitz_pm.c:170:15: error: no previous prototype for 'spitzpm_read_devdata' [-Werror=missing-prototypes] The problem is that there is a declaration for each of these, but it's only seen by the caller and not the callee. Moving these into appropriate header files ensures that both use the same calling conventions and it avoids the warnings.

ARM: pxa: move clk register definitions to driver The clock register definitions are now used (almost) exclusively in the clk driver, and that relies on no other mach/*.h header files any more. Remove the dependency on mach/pxa*-regs.h by addressing the registers as offsets from a void __iomem * pointer, which is either passed from a board file, or (for the moment) ioremapped at boot time from a hardcoded address in case of DT (this should be moved into the DT of course).

clk: pxa: transfer CPU clock setting from pxa2xx-cpufreq This is the initial stage to transfer the pxa25x and pxa27x CPU clocks handling from cpufreq to the clock API. More precisely, the clocks transferred are : - cpll : core pll, known also as the CPU core turbo frequency - core : core, known also as the CPU actual frequency, being either the CPU core turbo frequency or the CPU core run frequency This transfer is a prequel to shrink the code in pxa2xx-cpufreq.c, so that it can become, at least in devicetree builds, the casual cpufreq-dt driver.

clk: pxa: core pll is not affected by t bit The t bit of clkfcfg doesn't affect the core pll clock, but it makes core clock select between core pll clock and core run clock. As such remove it from the core pll rate reporting function, while it remains in clk_pxa27x_core_get_parent().

ARM: pxa: define clock registers as __iomem We should not dereference registers as pointers, so use readl/writel instead for these registers. The clock registers are accessed in multiple files, so we have to change them all at once. I stumbled over these registers while looking at something unrelated. There are in fact other registers with the same problem, but I did not try to address those at this point.

clk: pxa: fix core frequency reporting unit Legacy drivers which are not yet ported, such as cpufreq-pxa[23]xx, rely on pxaXXx_get_clk_frequency_khz() to find the CPU core frequency. This reporting was broken because the expected unit is kHz and not Hz. Fix the reporting for pxa25x, pxa27x and pxa3xx. Fixes: fe7710fae477 ("clk: add pxa25x clock drivers") Fixes: d40670dc6169 ("clk: add pxa27x clock drivers") Fixes: 9bbb8a338fb2 ("clk: pxa: add pxa3xx clock driver") Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

clk: add pxa25x clock drivers Move pxa25x clock drivers from arch/arm/mach-pxa to driver/clk. In the move : - convert to new clock framework legacy clocks - provide clocks as before for platform data based boards - provide clocks through devicetree with clk-pxa-dt This is the preliminary step in the conversion. The remaining steps are : - pxa3xx - once PXA is fully converted to device tree, if that happens, clk-pxa2* and clk-pxa3* should only hold the core clocks which cannot be described in devicetree.
