As we've spent quite a bit of time sorting out regressions for v4.3 and are very late with these, I've kept the changes down to minimum: - A series of timer changes from Felipe Balbi to get us closer to moving the remaining timer code into drivers - A series of hwmod clean-up changes queued by Paul Walmsley - SoC detection clean-up to use soc_is instead of cpu_is as CPU is within the SoC and is confusing naming. The rest we can now change along with the other clean-up * tag 'omap-for-v4.4/soc-clean-up' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (21 commits) ARM: OMAP3: hwmod data: Remove legacy mailbox data and addrs ARM: DRA7: hwmod data: Remove spinlock hwmod addrs ARM: OMAP4: hwmod data: Remove spinlock hwmod addrs ARM: DRA7/AM335x/AM437x: hwmod: Remove gpmc address space from hwmod data arm: omap2: board-generic: use omap4_local_timer_init for AM437x ARM: DRA7/AM335x/AM437x: hwmod: Remove elm address space from hwmod data ARM: OMAP: Remove duplicated operand in OR operation clocksource: ti-32k: make it depend on GENERIC_CLOCKSOURCE ARM: OMAP: Change all cpu_is_* occurences to soc_is_* for id.c ARM: OMAP2+: Rename cpu_is macros to soc_is arm: omap2: timer: limit hwmod usage to non-DT boots arm: omap2+: select 32k clocksource driver clocksource: add TI 32.768 Hz counter driver arm: omap2: timer: rename omap_sync32k_timer_init() arm: omap2: timer: always call clocksource_of_init() when DT arm: omap2: timer: move realtime_counter_init() around arm: omap2: timer: provide generic sync32k_timer_init function arm: omap2: timer: remove __omap_gptimer_init() arm: omap2: timer: add a gptimer argument to sync32k_timer_init() arm: omap2: timer: get rid of obfuscating macros ...

Instead of forcing all those devices to pass a use_gptimer cmdline argument, we add a new function argument to __omap_sync32k_timer_init() in preparation to deleting __omap_gptimer_init(). On a follow-up patch, we will remove uses of __omap_gptimer_init() and replace them with __omap_sync32k_timer_init() and pass the last argument as true. Signed-off-by: Felipe Balbi <balbi@ti.com>

Hence changing the SoC identification code to use soc_is instead of cpu_is and keeping defines for cpu_is where needed. This allows us to replace the rest of cpu_is usage along with other fixes as needed.

| * | ARM: OMAP2+: Rename cpu_is macros to soc_isTony Lindgren2015-10-161-89/+106
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The naming for the cpu_is macros is confusing as the CPU is separate and within the SoC. 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.

| * | ARM: pxa: magician: Rename charger cable detection EGPIOsPetr Cvek2015-10-142-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch renames EGPIOs, which are used for the charging cable presence and type detection. Old names did not correspond with an observed functionality (on board_id 0x3a). The behavior is not: - AC charger - USB charger - Cable detection , but: - AC/USB type - Cable detection1 - Cable detection2 This patch fixes a possible typo in the bit offset for the cable detection EGPIO declaration, too.
