clk: ti: change clock init to use generic of_clk_init

2014-09-29T08:51:13+00:00

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.)

ARM: OMAP5+: dpll: support Duty Cycle Correction(DCC)

2014-06-06T17:33:38+00:00

Duty Cycle Correction(DCC) needs to be enabled if the MPU is to run at frequencies beyond 1.4GHz for OMAP5, DRA75x, DRA72x. MPU DPLL has a limitation on the maximum frequency it can be locked at. Duty Cycle Correction circuit is used to recover a correct duty cycle for achieving higher frequencies (hardware internally switches output to M3 output(CLKOUTHIF) from M2 output (CLKOUT)). For further information, See the note on OMAP5432 Technical Reference Manual(SWPU282U) chapter 3.6.3.3.1 "DPLLs Output Clocks Parameters", and also the "OMAP543x ES2.0 DM Operating Conditions Addendum v0.5" chapter 2.1 "Micro Processor Unit (MPU)". Equivalent information is present in relevant DRA75x, 72x documentation(SPRUHP2E, SPRUHI2P).

ARM: OMAP2+: clock: fix clkoutx2 with CLK_SET_RATE_PARENT

2014-02-19T19:07:55+00:00

If CLK_SET_RATE_PARENT is set for a clkoutx2 clock, calling clk_set_rate() on the clock "skips" the x2 multiplier as there are no set_rate and round_rate functions defined for the clkoutx2. This results in getting double the requested clock rates, breaking the display on omap3430 based devices. This got broken when d0f58bd3bba3877fb1af4664c4e33273d36f00e4 and related patches were merged for v3.14, as omapdss driver now relies more on the clk-framework and CLK_SET_RATE_PARENT. This patch implements set_rate and round_rate for clkoutx2. Tested on OMAP3430, OMAP3630, OMAP4460. Signed-off-by: Tomi Valkeinen Acked-by: Tero Kristo Signed-off-by: Paul Walmsley
