Since any power on stabilisation delay for the supply itself should be taken care of transparently by the regulator API when the regulator is enabled the additional delay that the TPO-TD03MTEA1 driver adds after that returned should be due to the requirements of the device itself rather than the supply (the delay is also suspicously long for one for a regulator to ramp). Correct the comment to avoid misleading people taking this code as a reference. Signed-off-by:

It is possible for regulator_enable() to fail and if it does fail that's generally a bad sign for anything we try to do with the hardware afterwards so check for and immediately return an error if regulator_enable() fails. Signed-off-by:

The TAAL driver contains some regulator support which is currently unused (the code is there but the one panel supported by the driver doesn't have any regulators provided). This code mostly looks like an open coded version of the regulator core bulk API. The only additional feature is that a voltage range can be set once when the device is opened, though this is never varied at runtime. The general expectation is that if the device is not actively managing the voltage of the device (eg, doing DVFS) then any configuration will be done using the constraints rather than by drivers, saving them code and ensuring that they work well with systems where the voltage is not configurable. If systems are added needing regulator support this can be added back in, though it should be based on core features rather than open coding things. Signed-off-by:

For some OMAP versions the TRM says that the pixel clock from DISPC can be used as an input clock for DSI PLL, instead of the default, which is sysclk. For some OMAP versions the bits affecting this are marked as reserved. This feature has never been tested, so it's unknown if the HW even works, and has never been used. To clean things up, this patch removes the functionality. This should not affect any board. Signed-off-by:

Most of the DSS clocks have restrictions on their frequency based on the OPP in use. For example, maximum frequency for a clock may be 180MHz in OPP100, but 90MHz in OPP50. This means that when a high enough pixel clock or function clock is required, we need to use OPP100. However, there's currently no way in the PM framework to make that kind of request. The closest we get is to ask for very high bus throughput from the PM framework, which should effectively force OPP100. This patch is a simple version for handling the problem. Instead of asking for OPP100 only when needed, this patch asks for OPP100 whenever DSS is active. This obviously is not an optimal solution for cases with small displays where OPP50 would work just fine. However, a proper solution is a complex one, and this patch is a short term solution for the problem. Signed-off-by:

Commit c79396c1 ("mmc: sdhci: prevent card detection activity for non-removable cards") disables card detection where the cards are marked as non-removable. This makes sense, but the implementation detail of calling mmc_card_is_removable() causes some problems, because mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root filesystem is stored on SD, but we also have external SD card slots where we want automatic card detection. Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE, which is defined to mean that the card is *really* nonremovable. This could be revisited in future if we find a way to improve CONFIG_MMC_UNSAFE_RESUME semantics. Signed-off-by:

This continues the theme started with vm_brk() and vm_munmap(): vm_mmap() does the same thing as do_mmap(), but additionally does the required VM locking. This uninlines (and rewrites it to be clearer) do_mmap(), which sadly duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have to export our internal do_mmap_pgoff() function. Some day we hopefully don't have to export do_mmap() either, if all modular users can become the simpler vm_mmap() instead. We're actually very close to that already, with the notable exception of the (broken) use in i810, and a couple of stragglers in binfmt_elf. Signed-off-by:

of_have_populated_dt() is not expected to be used in drivers but instead only in early platform init code. Drivers on the other hand should rely on dev->of_node or of_match_device(). Besides usage of of_have_populated_dt() also throws up build error as below which was reported by Balaji TK, when omap_hsmmc is built as a module. ERROR: "allnodes" [drivers/mmc/host/omap_hsmmc.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 So get rid of all of_have_populated_dt() usage in omap_hsmmc driver and instead use dev->of_node to make the same dicisions as earlier.

eMMC v4.5 discard operation is significantly different from the existing trim operation because it is not guaranteed to work with the new sanitize operation. Consequently mmc_can_trim() is separated from mmc_can_discard(). Also the new discard operation does not result in the sectors being set to all-zeros, so discard_zeroes_data must not be set. In addition, the new discard has the same timeout as trim, but from v4.5 trim is defined to use the hc timeout. The timeout calculation is adjusted accordingly. Fixes apply to linux 3.2 on.
