Also fixed few typos. So here's the resent series: Attached patch series starts syncing up arch/arm/mach-omap2 directory with linux-omap tree. The patchset updates pin multiplexing, register access and clock framework in order to add support for 34xx later on. The register access and clock framework changes are quite large, but they allow us to share clock and PM code with 24xx and 34xx. I've combined Paul's register access and clock framework changes into larger patches, as in the linux-omap tree they have been done in many add-replace-fix cycles. Regards, Tony ------------------------------------------------------------------- List admin: http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm-kernel FAQ: http://www.arm.linux.org.uk/mailinglists/faq.php Etiquette: http://www.arm.linux.org.uk/mailinglists/etiquette.php ^ permalink raw reply [flat|nested] 36+ messages in thread

Clock framework register access will get updates in the next patch. Note that board-*.c files change GPMC (General Purpose Memory Controller) access to use gpmc_cs_write_reg() instead of accessing the registers directly. The H4 board file also adds h4_init_flash() function, which specyfy the flash start and end addresses. Also note that sleep.S removes some unused registers addresses.

Note that patch adds some temporary OLD_CK defines to keep patch more readable. These temporary defines will be removed in the next patch. Also not all clocks are changed in this patch to limit the size. Also, the patch fixes few incorrect clock defines in clock24xx.h.

His ideas are included into this patch. Remove DPLL output divider handling from DPLLs and CLKOUTX2 clocks, and place it into specific DPLL output divider clocks (e.g., dpll3_m2_clk). omap2_get_dpll_rate() now returns the correct DPLL rate, as represented by the DPLL's CLKOUT output. Also add MPU and IVA2 subsystem clocks, along with high-frequency bypass support. Add support for DPLLs function in locked and bypass clock modes.

His ideas are included into this patch. Remove DPLL output divider handling from DPLLs and CLKOUTX2 clocks, and place it into specific DPLL output divider clocks (e.g., dpll3_m2_clk). omap2_get_dpll_rate() now returns the correct DPLL rate, as represented by the DPLL's CLKOUT output. Also add MPU and IVA2 subsystem clocks, along with high-frequency bypass support. Add support for DPLLs function in locked and bypass clock modes.

Or this code is not designed for > CONFIG_PREEMPT? Yeah, it's OK. Both clk24xx.c and clk34xx.c register omap2_clk_enable() with omap common clock code. Then omap common clock code calls omap2_clk_enable() with spin_lock_irqsave(), see clk_enable() in arch/arm/plat-omap/clock.c.

This has been fixed with following changes: - Use gpmc_fck instead of core_l3_ck as core_l3_ck is not the right clock to use (although the rates are the same as it's the parent). - Mark gpmc_fck with ENABLE_ON_INIT so it's always on and autoidled - Remove fixed rate setting on clk_get() error, it's not needed Here's how it now looks: @@ -302,15 +288,17 @@ int eth_cs; unsigned long cs_mem_base; unsigned int muxed, rate; - struct clk *l3ck; + struct clk *gpmc_fck; eth_cs = H4_SMC91X_CS; - l3ck = clk_get(NULL, "core_l3_ck"); - if (IS_ERR(l3ck)) - rate = 100000000; - else - rate = clk_get_rate(l3ck); + gpmc_fck = clk_get(NULL, "gpmc_fck"); /* Always on ENABLE_ON_INIT */ + if (IS_ERR(gpmc_fck)) { + WARN_ON(1); + return; + } + + rate = clk_get_rate(gpmc_fck); if (is_gpmc_muxed()) muxed = 0x200; Will repost the whole series.

Here's an updated version of this patch. I've folded in two more patches from Paul [1][2]. Patches change to use __ffs() instead of mask_to_shift, and clean up clock register defines.

Only change USB platform init code to use new register access, other access will be changed in later patches.

The patchset updates pin multiplexing, register access and clock framework in order to add support for 34xx later on. The register access and clock framework changes are quite large, but they allow us to share clock and PM code with 24xx and 34xx. I've combined Paul's register access and clock framework changes into larger patches, as in the linux-omap tree they have been done in many add-replace-fix cycles.

Only change USB platform init code to use new register access, other access will be changed in later patches.
