2014-10-05ARM: DRA7: hwmod: Add dra74x and dra72x specific ocp interface listsRajendra Nayak
commit f7f7a29bf0cf25af23f37e5b5bf1368b85705286 upstream. To deal with IPs which are specific to dra74x and dra72x, maintain seperate ocp interface lists, while keeping the common list for all common IPs. Move USB OTG SS4 to dra74x only list since its unavailable in dra72x and is giving an abort during boot. The dra72x only list is empty for now and a placeholder for future hwmod additions which are specific to dra72x.

2014-09-05ARM: OMAP2+: hwmod: Rearm wake-up interrupts for DT when MUSB is idledTony Lindgren
commit cc824534d4fef0e46e4486d5c1e10d3c6b1ebadc upstream. Looks like MUSB cable removal can cause wake-up interrupts to stop working for device tree based booting at least for UART3 even as nothing is dynamically remuxed. This can be fixed by calling reconfigure_io_chain() for device tree based booting in hwmod code. Note that we already do that for legacy booting if the legacy mux is configured. My guess is that this is related to UART3 and MUSB ULPI hsusb0_data0 and hsusb0_data1 support for Carkit mode that somehow affect the configured IO chain for UART3 and require rearming the wake-up interrupts. In general, for device tree based booting, pinctrl-single calls the rearm hook that in turn calls reconfigure_io_chain so calling reconfigure_io_chain should not be needed from the hwmod code for other events. So let's limit the hwmod rearming of iochain only to HWMOD_FORCE_MSTANDBY where MUSB is currently the only user of it. If we see other devices needing similar changes we can add more checks for it.

2014-07-09ARM: OMAP2+: Fix parser-bug in platform muxing codeDavid R. Piegdon
commit c021f241f4fab2bb4fc4120a38a828a03dd3f970 upstream. Fix a parser-bug in the omap2 muxing code where muxtable-entries will be wrongly selected if the requested muxname is a *prefix* of their m0-entry and they have a matching mN-entry. Fix by additionally checking that the length of the m0_entry is equal. For example muxing of "dss_data2.dss_data2" on omap32xx will fail because the prefix "dss_data2" will match the mux-entries "dss_data2" as well as "dss_data20", with the suffix "dss_data2" matching m0 (for dss_data2) and m4 (for dss_data20). Thus both are recognized as signal path candidates: Relevant muxentries from mux34xx.c: _OMAP3_MUXENTRY(DSS_DATA20, 90, "dss_data20", NULL, "mcspi3_somi", "dss_data2", "gpio_90", NULL, NULL, "safe_mode"), _OMAP3_MUXENTRY(DSS_DATA2, 72, "dss_data2", NULL, NULL, NULL, "gpio_72", NULL, NULL, "safe_mode"), This will result in a failure to mux the pin at all: _omap_mux_get_by_name: Multiple signal paths (2) for dss_data2.dss_data2 Patch should apply to linus' latest master down to rather old linux-2.6 trees.

2014-06-11ARM: OMAP4: Fix the boot regression with CPU_IDLE enabledSantosh Shilimkar
commit 4b353a706a86598ba47307c47301c3c428b79e09 upstream. On OMAP4 panda board, there have been several bug reports about boot hang and lock-ups with CPU_IDLE enabled. The root cause of the issue is missing interrupts while in idle state. Commit cb7094e8 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP flag} moved the broadcast notifiers to common code for right reasons but on OMAP4 which suffers from a nasty ROM code bug with GIC, commit ff999b8a {ARM: OMAP4460: Workaround for ROM bug ..}, we loose interrupts which leads to issues like lock-up, hangs etc. Patch reverts commit cb7094 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP flag} and 54769d6 {cpuidle: OMAP4: remove timer broadcast initialization} to avoid the issue. With this change, OMAP4 panda boards, the mentioned issues are getting fixed. We no longer loose interrupts which was the cause of the regression.

commit 3d36ad7e7a9be0d130c862727a052ed279046437 upstream. Bug was introduced by commit 'f92d959: ARM: OMAP2+: hwmod: Extract no-idle and no-reset info from DT' There were 2 versions of the patch posted which resulted in the above commit. While v1 [1] had the bug, v2 [2] had it fixed. However v1 apparently seemed to have been pulled in by mistake introducing the bug. Given of_find_property() does return NULL when the node passed is NULL, it did not introduce any functional issues as such, just the fact that the second if check was executed unnecessarily.

2014-05-06ARM: OMAP2+: INTC: Acknowledge stuck active interruptsStefan Sørensen
commit 698b48532539484b012fb7c4176b959d32a17d00 upstream. When an interrupt has become active on the INTC it will stay active until it is acked, even if masked or de-asserted. The INTC_PENDING_IRQn registers are however updated and since these are used by omap_intc_handle_irq to determine which interrupt to handle, it will never see the active interrupt. This will result in a storm of useless interrupts that is only stopped when another higher priority interrupt is asserted. Fix by sending the INTC an acknowledge if we find no interrupts to handle.

2014-02-19ARM: OMAP2+: clock: fix clkoutx2 with CLK_SET_RATE_PARENTTomi Valkeinen
If CLK_SET_RATE_PARENT is set for a clkoutx2 clock, calling clk_set_rate() on the clock "skips" the x2 multiplier as there are no set_rate and round_rate functions defined for the clkoutx2. This results in getting double the requested clock rates, breaking the display on omap3430 based devices. This got broken when d0f58bd3bba3877fb1af4664c4e33273d36f00e4 and related patches were merged for v3.14, as omapdss driver now relies more on the clk-framework and CLK_SET_RATE_PARENT. This patch implements set_rate and round_rate for clkoutx2. Tested on OMAP3430, OMAP3630, OMAP4460.

Some of them are fixes, but a good number of them also do things such as enable new drivers in the defconfigs for platforms that have such devices, increases coverage of the multiplatform defconfig and some DTS changes that plumbs up some of the devices that now have bindings and driver support. The commit dates are recent; we've mostly collected these fixes in the last few days but I also had to rebuild the branch yesterday to sort out some internal conflicts which reset the timestamps.

2014-01-17ARM: OMAP3: hwmod: initialize clkdm from clkdm_nameTero Kristo
DT clocks are mostly missing clkdm info now, and this causes an issue with counter32k which makes its slave idlemode wrong and prevents core idle. Fixed by initializing the hwmod clkdm pointers for omap3 also which makes sure the clkdm flag matching logic works properly. This patch also changes the return value for _init_clkdm to 0 for incorrect clkdm_name, as this a warning, not a fatal error.
