2014-04-25ARM: dts: am437x-gp-evm: Do not reset gpio5Dave Gerlach
Do not reset GPIO5 at boot-up because GPIO5_7 is used on AM437x GP-EVM to control VTT regulators on DDR3. Without this some GP-EVM boards will fail to boot because of DDR3 corruption.

2014-04-25ARM: dts: omap3-igep0020: use SMSC9221 timingsJavier Martinez Canillas
The IGEPv2 board has a SMSC LAN9221i ethernet chip and not a SMSC LAN911x connected to the GPMC. Each chip needs different timings in order to operate correctly so is wrong to include omap-gpmc-smsc911x.dtsi instead of omap-gpmc-smsc9221.dtsi.

2014-04-23ARM: dts: Fix GPMC timings for LAN9220Tony Lindgren
I've noticed occasional random oopsing on my gateway machine since I upgraded it to use device tree based booting. As this machine has worked reliably before that for a few years, pretty much the only difference was narrowed down to the GPMC timings. Turns out that for legacy based booting we are using bootloader timings for GPMC for smsc911x. With device tree we are passing the timings in the .dts file, and the device tree timings are not quite suitable for LAN9920. Enabling DEBUG in gpmc.c I noticed that the device tree configured timings are different from the the known working bootloader timings. So let's fix the timings to match the bootloader timings when looked at the gpmc dmesg output with DEBUG enabled. The changes were done by multiplying the bootloader tick values by six to get the nanosecond value for device tree. This is not generic from the device point of view as the calculations should be based on the device timings. Anyways, further improvments can be done based on the timings documentation for LAN9220. But let's first get things to a known good working state. Note that we still need to change the timings also for sb-t35 also as it has two LAN9220 instances on GPMC and we can currently include the generic timings only once. Also note that any boards that have LAN9221 instead of LAN9220 should be updated to use omap-gpmc-smsc9221.dtsi instead of omap-gpmc-smsc911x.dtsi. The LAN9221 timings are different from LAN9220 timings.

2014-04-23ARM: dts: Fix GPMC Ethernet timings for omap cm-t sbc-t boards for device treeTony Lindgren
Looks like we have wrong GPMC timings we have for the cm-t and sbc-t boards. This can cause occasional strange errors with at least doing an rsync of large files or doing apt-get dist-upgrade. Let's fix the issue in two phases. First let's simplify cm-t and sbc-t to use the shared omap-gpmc-smsc911x.dtsi to avoid fixing the issue in multiple places. Then we can fix the timings in a single place with a follow-up patch. Cc: Dmitry Lifshitz <lifshitz@compulab.co.il> Signed-off-by: Tony Lindgren <tony@atomide.com>
2014-04-23ARM: dts: Fix bad OTG muxing for cm-t boardsTony Lindgren
Looks like the OTG pins are off by 2 and we get this: pinctrl-single 48002030.pinmux: pin 480021a0.0 already requested by 49020000.serial; cannot claim for 480ab000.usb_otg_hs pinctrl-single 48002030.pinmux: pin-184 (480ab000.usb_otg_hs) status -22 pinctrl-single 48002030.pinmux: could not request pin 184 (480021a0.0) from group pinmux_hsusb0_pins on device pinctrl-single musb-omap2430 480ab000.usb_otg_hs: Error applying setting, reverse things back That's probably because the TRM lists the values as 32-bit registers so every second needs 2 added to the address. The OTG pin start range must start from 0x21a2, not 0x21a0. Cc: Dmitry Lifshitz <lifshitz@compulab.co.il> Signed-off-by: Tony Lindgren <tony@atomide.com>
2014-04-23ARM: OMAP2+: Fix GPMC remap for devices using an offsetTony Lindgren
At least the smc91x driver expects the device to be at 0x300 offset from bus base address. This does not work currently for GPMC when booted in device tree mode as it attempts to remap the the allocated GPMC partition to the address configured by the device tree plus the device offset. Note that this works just fine when booted with legacy mode. Let's fix the issue by just ignoring any device specific offset while remapping. And let's make sure the remap address confirms to the GPMC 16MB minimum granularity as listed in the TRM for GPMC_CONFIG7 BASEADDRESS bits. Otherwise we can get something like this: omap-gpmc 6e000000.gpmc: cannot remap GPMC CS 1 to 0x01000300 Cc: Pekon Gupta <pekon@ti.com> Reviewed-by: Javier Martinez Canillas <javier@dowhile0.org> Signed-off-by: Tony Lindgren <tony@atomide.com>
2014-04-21ARM: OMAP2+: Fix oops for GPMC freeTony Lindgren
If gpmc_cs_remap() fails we will get an error because we are calling release_resource() on an uninitialized resource. Let's fix that by checking the resource flags. And while at it, let's also make gpmc_cs_delete_mem() use the res pointer that we already have to avoid confusion. Without this patch we can get the following error: omap-gpmc 6e000000.gpmc: cannot remap GPMC CS 1 to 0x01000300 Unable to handle kernel NULL pointer dereference at virtual address 00000018 ...

2014-04-11ARM: OMAP2+: hwmod: fix missing braces in _init()Suman Anna
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.

2014-04-07Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAPUwe Kleine-König
If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT. The changes in this commit were done using: $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/' Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2014-04-07ARM: 8009/1: dcscb.c: remove call to outer_flush_all()Nicolas Pitre
Strictly speaking this call is a no-op on the platform where dcscb.c is used since it only has architected caches. The call was there as a hint to people inspired by this code when writing their own backend, but the hint might not always be correct. For example, if a PL310 were to be used it wouldn't be safe to call the regular outer_flush_all() as atomic instructions for locking are involved in that case and those instructions cannot be assumed to still be operational after v7_exit_coherency_flush() has returned. Given no other CPUs (in the cluster) should be running at that point then standard concurrency concerns wouldn't apply. So let's simply kill this call for now and enhance the existing comment.
