2012-10-16OMAPDSS: add omapdss_versionTomi Valkeinen
Add new enum, omapdss_version, that is used to tell which DSS hardware version the SoC has. This enum is initialized during platform init, and passed in the platform data to omapdss driver. Note that the versions are not "continuous", that is, you cannot check if the version is less or greater than something, but you need to check for exact version match. In other words, this is invalid: /* test if DSS is 3630 or earlier */ if (ver <= OMAPDSS_VER_OMAP3630) ... Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2012-10-16usb: gadget: lpc32xx_udc: Fix compatibility with STOTG04Alexandre Pereira da Silva
The STOTG04 is an replacement for ISP1301. Most of the registers on STOTG04 are the same as on ISP1301, but the register ISP1301_I2C_OTG_CONTROL_2 (address 0x10) doesn't exist on the ST part. This is a work around for this by using the interrupt source register that should behave the same on both parts and has the needed information.

When interrupt happened, renesas_usbhs driver gets irq status by usbhs_status_get_each_irq(), and cleared all status by using 0. But, this method is incorrect, since extra interrupt might occur between them.

__usbhs_for_each_pipe() is the macro which moves around each pipe, but it has a bug which didn't care about 1st pipe's position. Because of this bug, it moves around pipe0, pipe2, pipe3 ... even though it requested pipe1, pipe2, pipe3... This patch modifies it.

2012-10-16drm/nouveau/pm: do not stop reclocking if failing to set the fan speedMartin Peres
With the introduction of fan management modes, fan may not be drivable. We should allow reclocking nonetheless. This return was stupid to begin with since it may have left the card in an intermediate state (clocks corresponding to a perflvl and voltage corresponding to another one). The reclocking code will need to be rewritten in a near-future in order to provide a better error handling.

2012-10-15xtensa: copy_thread with CLONE_VM must not copy live parent AR windowsMarc Gauthier
When doing a fork (new VM), the new task has a mirror image of the parent's stack, so keeps the same live register windows etc. However when doing a clone with CLONE_VM, keeping the same VM (eg. when creating a new thread), the child starts afresh on a new stack -- it cannot share any part of the parent stack. It especially cannot have the same live AR windows as the parent, otherwise it will overwrite the parent stack on overflow, likely causing corruption. (and so it did...) Effectively, the register windows need to be spilled. Turns out it's much easier to simply not copy parent register windows when CLONE_VM is set.

2012-10-15ARM: OMAP: Trivial driver changes to remove include plat/cpu.hTony Lindgren
Drivers should not use cpu_is_omap or cpu_class_is_omap macros, they should be private to the platform init code. And we'll be removing plat/cpu.h and only have a private soc.h for the arch/arm/*omap* code. This patch is intended as preparation for the core omap changes and removes the need to include plat/cpu.h from several drivers. This is needed for the ARM common zImage support. These changes are OK to do because: - omap-rng.c does not need plat/cpu.h - omap-aes.c and omap-sham.c get the proper platform_data passed to them so they don't need extra checks in the driver - omap-dma.c and omap-pcm.c can test the arch locally as omap1 and omap2 cannot be compiled together because of conflicting compiler flags Cc: Deepak Saxena <dsaxena@plexity.net> Cc: Matt Mackall <mpm@selenic.com> Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: David S.

Based on Dmitries work, but splitting the code into page directory and page table handling makes it far more readable and (hopefully) more reliable. Allocations of page tables are made from the SA on demand, that should still work fine since all page tables are of the same size. Also using the fact that allocations from the SA are mostly continuously (except for end of buffer wraps and under very high memory pressure) to group updates send to the chipset specific code into larger chunks. v3: mostly a rewrite of Dmitries previous patch. v4: fix some typos and coding style Signed-off-by: Dmitry Cherkasov <Dmitrii.Cherkasov@amd.com> Signed-off-by: Christian König <deathsimple@vodafone.de> Tested-by: Michel Dänzer <michel.daenzer@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
