We have hp t410 already booting in mainline kernel with it's bootloader configured clocks. However, trying to boot dm814x-evm uncovered all kind of issues with the timer clock. To keep t410 booting, these issues need to be fixed in a specific order and this branch contains both device tree and code changes. To summarize the changes, we had missing ranges for clocks to probe, missing aliase for clocks, wrong registers for divder clocks, and bad address for the control module. All these went unnoticed earlier as things worked without errors by luck and I did not pay much attention to them until I got hold of a dm814x-evm and I noticed it did not boot. As these are fixes for features that never worked, these can wait for v4.5 merge window no problem. * tag 'omap-for-v4.5/81xx-fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Remove useless check for legacy booting for dm814x ARM: OMAP2+: Enable GPIO for dm814x ARM: dts: Fix dm814x pinctrl address and mask ARM: dts: Fix dm8148 control modules ranges ARM: OMAP2+: Fix timer entries for dm814x ARM: dts: Fix some mux and divider clocks to get dm814x-evm booting ARM: OMAP2+: Add DPPLS clock manager for dm814x clk: ti: Add few dm814x clock aliases ARM: dts: Fix dm814x entries for pllss and prcm

The bulk of the changes are to clk controller drivers, though some improvements to the core and some re-usable blocks/templates also received some love. In this past cycle the clk maintainers developed a good workflow for handling the common case of patch submissions containing a new drivers, new shared Device Tree header and a new Device Tree binding description. This requires coordination with the Device Tree maintainers and with the architecture maintainers (typically the arm-soc tree in our case). This explains the increase in changes to include/dt-bindings/... and to Documentation/devicetree/bindings/clock/... coming from the clk tree.

As a workaround, before re-programming the M/N ratio, SW has to ensure the DPLL cannot start an idle state transition. SW can disable DPLL idling by setting the DPLL AUTO_DPLL_MODE=0 or keeping a clock request active by setting a dependent clock domain in SW_WKUP. This errata impacts OMAP5 and DRA7 chips, so enable the errata for these. Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

* | | | | ARM: OMAP2+: Fix onenand rate detection to avoid filesystem corruptionTony Lindgren2016-01-061-5/+9

The commit also left out the option for HWMOD_INIT_NO_RESET as we now require proper timings for GPMC to be able to remap GPMC devices out of address 0. Unfortunately on Nokia N900, onenand now only partially works with the device tree provided timings. It works enough to get detected but the clock rate supported by the onenand chip gets misdetected. This in turn causes the GPMC timings to be miscalculated and this leads into file system corruption on N900. Looks like onenand needs CS_CONFIG1 bit 27 WRITETYPE set for for sync write. This is needed also for async timings when we write to onenand with omap2_onenand_set_async_mode(). Without sync write bit set, the async read for the onenand ONENAND_REG_VERSION_ID will return 0xfff. Let's exit with an error if onenand rate is not detected. And let's remove the extra call to omap2_onenand_set_async_mode() as we only need to do this once at the end of omap2_onenand_setup_async().

In the above case, It's expected that broadcast timer will be used as backup timer when CPUIdle will put MPU in low power states where ARM TWD will stop and lose its context. But, the CONFIG_SMP might not be selected when kernel is built for AM43XX SoC only and, as result, GENERIC_CLOCKEVENTS_BROADCAST option will not be selected also. This will break CPUIdle and System will stuck in low power states. Hence, fix it by selecting GENERIC_CLOCKEVENTS_BROADCAST option for AM43XX SoCs always and add empty tick_broadcast() function implementation - no need to send any IPI on UP. After this change timer1 will be selected as broadcast timer the same way as for SMP, and CPUIdle will work properly.

Let's rename all the macros to soc_is, and let's define cpu_is also for the ones still in use. Then we can just remove the cpu_is macros once the users are fixed up. To keep the chances of breaking anything, the changes were generated with the following regular expressions: s/cpu_is/soc_is/g s/CPU/SoC/g Then the list of existing cpu_is users was generated with: $ $ grep -o -e 'cpu_is_.\+()' arch/arm/mach-omap2/*.[chS] | \ cut -d: -f2 | sort | uniq And added to the end of the soc.h. I decided to rework the earlier patches by Keerthy <j-keerthy@ti.com> to keep changes down to minimum to avoid potential errors and stick to just search and replace.
