OMAP3/4 clock: split into per-chip family files clock34xx_data.c now contains data for the OMAP34xx family, the OMAP36xx family, and the OMAP3517 family, so rename it to clock3xxx_data.c. Rename clock34xx.c to clock3xxx.c, and move the chip family-specific clock functions to clock34xx.c, clock36xx.c, or clock3517.c, as appropriate. So now "clock3xxx.*" refers to the OMAP3 superset. The main goal here is to prepare to compile chip family-specific clock functions only for kernel builds that target that chip family. To get to that point, we also need to add CONFIG_SOC_* options for those other chip families; that will be done in future patches, planned for 2.6.35. OMAP4 is also affected by this. It duplicated the OMAP3 non-CORE DPLL clkops structure. The OMAP4 variant of this clkops structure has been removed, and since there was nothing else currently in clock44xx.c, it too has been removed -- it can always be added back later when there is some content for it. (The OMAP4 clock autogeneration scripts have been updated accordingly.)

OMAP3630: Clock: Workaround for DPLL HS divider limitation This patch implements a workaround for the DPLL HS divider limitation in OMAP3630 as given by Errata ID: i556. Errata: When PWRDN bit is set, it resets the internal HSDIVIDER divide-by value (Mx). The reset value gets loaded instead of the previous value. The following HSDIVIDERs exhibit above behavior: . DPLL4 : M6 / M5 / M4 / M3 / M2 (CM_CLKEN_PLL[31:26] register bits) . DPLL3 : M3 (CM_CLKEN_PLL[12] register bit). Work Around: It is mandatory to apply the following sequence to ensure the write value will be loaded in DPLL HSDIVIDER FSM: The global sequence when using PWRDN bit is the following: . Disable Mx HSDIVIDER clock output related functional clock enable bits (in CM_FCLKEN_xxx / CM_ICLKEN_xxx) . Enable PWRDN bit of HSDIVIDER . Disable PWRDN bit of HSDIVIDER . Read current HSDIVIDER register value . Write different value in HSDIVIDER register . Write expected value in HSDIVIDER register . Enable Mx HSDIVIDER clock output related functional clocks (CM_FCLKEN_xxx / CM_ICLKEN_xxx) Signed-off-by: Mike Turquette <mturquette@ti.com> Signed-off-by: Vishwanath BS <vishwanath.bs@ti.com> Signed-off-by: Vijaykumar GN <vijaykumar.gn@ti.com> [paul@pwsan.com: updated patch to apply; made workaround function static; marked as being 36xx-specific] Signed-off-by: Paul Walmsley <paul@pwsan.com>
