| * ARM: OMAP2+: Get rid of custom OMAP_32K_TIMER_HZSantosh Shilimkar2013-02-012-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The timekeeping doesn't depend on HZ value in presence of fine grained clocksource and hence there should not be any time drift because of HZ value which was chosen to be divisor of 32768. OMAP has been using HZ = 128 value to avoid any time drift issues because of 32768 HZ clock. But with various measurements performed with HZ = 100, no time drift is observed and it also proves the point about HZ not having impact on time keeping on OMAP. Very informative thread on this topic is here: https://lkml.org/lkml/2013/1/29/435 Special thanks to John Stulz, Arnd Bergmann and Russell King for their valuable suggestions.

Fix the issue by making the problem drivers depends !ARCH_MULTIPLATFORM for now. The remaining pieces that are not multiplatform compatible for omap2+ SoCs are: 1. Some drivers are using custom omap_dm_timer calls There are two drivers that are directly usign omap hardware timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and drivers/staging/tidspbridge/core/dsp-clock.c. These can be fixed for multiplatform by allowing a minimal set of hardware timers to be accessed, and for some functionality by using the hrtimer framework. 2. Hardware OMAP4_ERRATA_I688 needs to be fixed up This can't be enabled for multiplatform configurations in it's current form. It may be possible to fix it up to do instruction replacement early on during init. Luckily it looks like this errata does not seem to get hit with mainline kernel code alone at least currently. 3. Legacy header needed for omap-sham.c Looks like it still needs mach/irqs.h for omap1 that does not exist for multiplatform systems. Just ifdef it for now. 4. Mailbox is waiting to get moved to drivers Disable it for now to avoid adding a dependency to the mailbox patches.

Unfortunately that was before I was able to try to test compile of the ARM multiplatform builds for omap2+, and the end result was not very good. So I'm creating yet another all over the place patch to cut the last dependency for building omap2+ for ARM multiplatform. After this, we have finally removed the driver dependencies to the arch/arm code, except for few drivers that are being worked on. The other option was to make the <plat-omap/dma-omap.h> path to work, but we'd have to add some new header directory to for multiplatform builds. Or we would have to manually include arch/arm/plat-omap/include again from arch/arm/Makefile for omap2+. Neither of these alternatives sound appealing as they will likely lead addition of various other headers exposed to the drivers, which we want to avoid for the multiplatform kernels. Since we already have a minimal include/linux/omap-dma.h, let's just use that instead and add a note to it to not use the custom omap DMA functions any longer where possible. Note that converting omap DMA to dmaengine depends on dmaengine supporting automatically incrementing the FIFO address at the device end, and converting all the remaining legacy drivers. So it's going to be few more merge windows.

Make OMAP2+ timer code independant from the CONFIG_OMAP_32K_TIMER setting. To remove the dependancy, several conversions/additions had to be done: 1) Timer initialization functions are named by the platform name and the clock source in use. This also makes it possible to define and use the GPTIMER as the clock source instead of the 32K timer on platforms that do not have the 32K timer ip block or the 32K timer is not wired on the board. Currently, the the timer is chosen in the machine_desc structure on per board basis. Later, DT should be used to choose the timer. 2) Settings under the CONFIG_OMAP_32K_TIMER option are used as defaults and those under !CONFIG_OMAP_32K_TIMER are removed. This removes the CONFIG_OMAP_32K_TIMER on OMAP2+ timer code. 3) Since we have all the timers defined inside machine_desc structure and we no longer need the fallback to gp_timer clock source in case 32k_timer clock source is unavailable (namely on AM33xx), we no longer need the #ifdef around omap2_sync32k_clocksource_init() function. Remove the #ifdef CONFIG_OMAP_32K_TIMER around the omap2_sync32k_clocksource_init() function.

Therefore combine these into a single function called omap_dm_timer_reset() and simplify the code. The omap_dm_timer_reset() function is now the only place that is using the omap_dm_timer structure member "sys_stat". Therefore, remove this member and just use the register offset definition to simplify and clean-up the code. The TISTAT register is only present on revision 1 timers and so check for this in the omap_dm_timer_reset() function. Please note that for OMAP1 devices, the TIOCP_CFG register does not have the clock-activity field and so when we reset the timer for an OMAP1 device we only need to configure the idle-mode field in the TIOCP_CFG register.

Therefore, we can remove this code from the dmtimer driver and move it to the system timer code for OMAP2+ devices. The current __omap_dm_timer_set_source() function calls clk_disable() before calling clk_set_parent() and clk_enable() afterwards. We can avoid these calls to clk_disable/enable by moving the calls to omap_hwmod_setup_one() and omap_hwmod_enable() to after the call to clk_set_parent() in omap_dm_timer_init_one(). The function omap_hwmod_setup_one() will enable the timers functional clock and therefore increment the use-count of the functional clock to 1. clk_set_parent() will fail if the use-count is not 0 when called. Hence, if omap_hwmod_setup_one() is called before clk_set_parent(), we will need to call clk_disable() before calling clk_set_parent() to decrement the use-count. Hence, avoid these extra calls to disable and enable the functional clock by moving the calls to omap_hwmod_setup_one() and omap_hwmod_enable() to after clk_set_parent(). We can also remove the delay from the __omap_dm_timer_set_source() function because enabling the clock will now be handled via the HWMOD framework by calling omap_hwmod_setup_one(). Therefore, by moving the calls to omap_hwmod_setup_one() and omap_hwmod_enable() to after the call to clk_set_parent(), we can simply replace __omap_dm_timer_set_source() with clk_set_parent(). It should be safe to move these hwmod calls to later in the omap_dm_timer_init_one() because other calls to the hwmod layer that occur before are just requesting resource information. Testing includes boot testing on OMAP2420 H4, OMAP3430 SDP and OMAP4430 Blaze with the following configurations: 1. CONFIG_OMAP_32K_TIMER=y 2. CONFIG_OMAP_32K_TIMER=y and boot parameter "clocksource=gp_timer" 3. CONFIG_OMAP_32K_TIMER not set 4. CONFIG_OMAP_32K_TIMER not set and boot parameter "clocksource=gp_timer" Signed-off-by: Jon Hunter <jon-hunter@ti.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com>

This is not necessary because on requesting a dmtimer we look-up the functional clock source and store it in the omap_dm_timer structure. So instead of looking up the clock again used the clock handle that stored in the omap_dm_timer structure.

For some timer instances the timer interrupt enable function can be used to disable the interrupts because the same interrupt enable register is used to disable interrupts. However, some timer instances have separate interrupt enable/disable registers and so this will not work. Therefore, add a dedicated function to disable interrupts. This change is required for OMAP4+ devices. For OMAP4, all timers apart from 1, 2 and 10 need this function and for OMAP5 all timers need this function. Please note that the interrupt disable function has been written so that it can be used by all OMAP devices.

When using this feature spurious interrupts were seen, because the compare logic is being enabled before the match value is loaded and according to the documentation the match value must be loaded before the compare logic is enable. The reset value for the timer counter and match registers is 0 and hence, by enabling the compare logic before the actual match value is loaded a spurious interrupt can be generated as the reset values match.

Furthermore, if an interrupt is pending when someone attempts to disable a timer, the timer will fail to transition to the idle state and hence it's context will not be lost. Users should take care to service all interrupts before disabling the timer. Signed-off-by: Jon Hunter <jon-hunter@ti.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com>

Although timer1 is still used by most OMAP2+ devices as a system timer, the function omap_dm_timer_reset() is now only being called for OMAP1 devices and OMAP1 does not use timer1 as a system timer.

This function is only being called for OMAP1 timers and OMAP2+ timers that are being used as system timers. Hence, for OMAP2+ timers that are NOT being used as a system timer, posted mode is not enabled but the "timer->posted" variable is still set (incorrectly) in the omap_dm_timer_prepare() function. This is a regression introduced by commit 3392cdd3 (ARM: OMAP: dmtimer: switch-over to platform device driver) which was before the omap_dm_timer_enable_posted() function was introduced. Although this is a regression from the original code it only impacts performance and so is not needed for stable.
