| | | | | | | | | | | | | | | | | | | | | | | | Commit 6bb27d7 "ARM: delete struct sys_timer" removed struct sys_timer, but didn't update mach-sunxi/sunxi.c for this change, even though the sunxi timer implementation itself was updated. This caused a build break: arch/arm/mach-sunxi/sunxi.c:94:2: error: unknown field 'timer' specified in initializer arch/arm/mach-sunxi/sunxi.c:94:12: error: 'sunxi_timer' undeclared here (not in a function) Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Olof Johansson <olof@lixom.net>
| * clocksource: add common of_clksrc_init() functionStephen Warren2013-01-025-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | It is desirable to move all clocksource drivers to drivers/clocksource, yet each requires its own initialization function. We'd rather not pollute <linux/> with a header for each function. Instead, create a single of_clksrc_init() function which will determine which clocksource driver to initialize based on device tree. Based on a similar patch for drivers/irqchip by Thomas Petazzoni. Signed-off-by: Stephen Warren <swarren@nvidia.com>
| * ARM: delete struct sys_timerStephen Warren2012-12-24495-1224/+629
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

| * ARM: remove struct sys_timer suspend and resume fieldsStephen Warren2012-12-242-45/+0
| | | | | | | | | | | | | | | | | | | | | | These fields duplicate e.g. struct clock_event_device's suspend and resume fields, so remove them now that nothing is using them. The aim is to remove all fields from struct sys_timer except .init, then replace the ARM machine descriptor's .timer field with a .init_time function instead, and delete struct sys_timer.

| * time: convert arch_gettimeoffset to a pointerStephen Warren2012-12-248-31/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, whenever CONFIG_ARCH_USES_GETTIMEOFFSET is enabled, each arch core provides a single implementation of arch_gettimeoffset(). In many cases, different sub-architectures, different machines, or different timer providers exist, and so the arch ends up implementing arch_gettimeoffset() as a call-through-pointer anyway. Examples are ARM, Cris, M68K, and it's arguable that the remaining architectures, M32R and Blackfin, should be doing this anyway. Modify arch_gettimeoffset so that it itself is a function pointer, which the arch initializes. This will allow later changes to move the initialization of this function into individual machine support or timer drivers. This is particularly useful for code in drivers/clocksource which should rely on an arch-independant mechanism to register their implementation of arch_gettimeoffset(). This patch also converts the Cris architecture to set arch_gettimeoffset directly to the final implementation in time_init(), because Cris already had separate time_init() functions per sub-architecture. M68K and ARM are converted to set arch_gettimeoffset to the final implementation in later patches, because they already have function pointers in place for this purpose.

A basic set of test logs are available here: http://www.pwsan.com/omap/testlogs/prcm_fixes_b_3.8-rc/20130102120724/ The 3730 Beagle XM here has an intermittent failure mounting SD root, but the suspicion right now is that this is due to a failing SD card, rather than any change introduced by these patches. This second version includes a few changes requested by Tony Lindgren.
| | | * | | ARM: OMAP2/3: PRM: fix bogus OMAP2xxx powerstate return valuesPaul Walmsley2013-01-023-28/+110

The order is reversed. So, for example, on OMAP2xxx, 0x0 indicates 'ON'; but on OMAP3/4, 0x0 indicates 'OFF'. Similarly, on OMAP2xxx, 0x3 indicates 'OFF', but on OMAP3/4, 0x3 indicates 'ON'. To fix this, we treat the OMAP3/4 values as the powerdomain API values, and create new low-level powerdomain functions for the OMAP2xxx chips which translate between the OMAP2xxx values and the OMAP3/4 values. Without this patch, the conversion of the OMAP2xxx PM code to the functional powerstate code results in a non-booting kernel. Signed-off-by: Paul Walmsley <paul@pwsan.com>

The emu_src_ck should enable the EMU clock domain so that the ETM/ETB hardware is accessible. However, currently when enabling the emu_src_ck the EMU clock domain is not being enabled and so the ETM/ETB drivers are failing. Add enable/disable clock functions to enable the EMU clock domain when enabling the emu_src_ck. Signed-off-by: Jon Hunter <jon-hunter@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since exynos5440 can support only common clk stuff, so this patch skips legacy exynos5 clock initialization. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
