* OMAP24xx I2C: Add support for set-speedHannes Petermaier2014-02-20-50/+97
| | | | | | | | | | | | | | | Adds support for set-speed on the OMAP24xx I2C Adapter. Changes to omap24_i2c_write(...) for polling ARDY Bit from IRQ-Status. Otherwise on a subsequent call the transfer of last byte from the predecessor is aborted and therefore lost. For exmaple when i2c_write(...) is followed by a i2c_setspeed(...) (which has to deactivate and activate master for changing psc,...). Minor cosmetical changes. Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at> Cc: Heiko Schocher <hs@denx.de>
* i2c: i2c-mxs: Wait for I2C to empty queueMarek Vasut2014-02-20-7/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make sure the I2C write queue is empty before leaving the mxs_i2c_write(). If we start and I2C write and only wait for ACK, the MXS I2C IP block may enter next operation while still processing the write aftermath internally. This will in turn disrupt one or more subsequent transfer(s). A testcase for this issue is as such. This testcase is also interesting because the first I2C_WRITE which becomes disruptive happens in the 'i2c read' command. The 'i2c read' command first uses I2C_WRITE to send I2C address of the chip and then uses I2C_READ to read data from the chip. After this command completes, the 'i2c probe' will use sequence of I2C_WRITE commands to probe the I2C bus. The problem is that the first I2C_WRITE disrupted the I2C IP block operation and this sideeffect propagates all the way to this next I2C_WRITE used by the 'i2c probe' call. The result is the 'i2c probe' receives an ACK on I2C address 0x00, even if this ACK was owned by the previous I2C_WRITE operation. Note that the 'i2c read' command must read from a valid I2C chip address. Wrong: > i2c probe Valid chip addresses: 50 51 > i2c read 0x50 0x0.2 0x10 0x42000000 > i2c probe Valid chip addresses: 00 50 51 With this patch > i2c probe Valid chip addresses: 50 51 > i2c read 0x50 0x0.2 0x10 0x42000000 > i2c probe Valid chip addresses: 50 51 Signed-off-by: Marek Vasut <marex@denx.de> Cc: Heiko Schocher <hs@denx.de> Cc: Fabio Estevam <festevam@gmail.com>

* kbuild: use Linux Kernel build scriptsMasahiro Yamada2014-02-19-13/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

* kbuild: change out-of-tree buildMasahiro Yamada2014-02-19-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

| * | mmc: tegra: support Tegra124Stephen Warren2014-02-03-0/+9
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra124's MMC controller is very similar to earlier SoC generations, and can be supported by the same driver. However, there are some non-backwards-compatible HW differences, and hence a new DT compatible value must be used to describe the HW. This patch updates the driver to support that new compatible value. That said, the HW differences are only relevant when enabling certain high-performance transfer modes. Since the driver is currently very simple and doesn't enable those modes, we don't actually need to address any of these HW differences in the code yet, hence the simple nature of this patch.

Note that after this change some previously used config options (driver-specific PHY configuration) will be obsolete and they are simply substituted with similar options of phylib. For example: * CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled by default. * CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise automatically the first discovered on MDIO bus phy will be used I believe there's no need now in "doc/README.designware_eth" because user only needs to instantiate the driver with "designware_initialize" whose prototype exists in "include/netdev.h".

Now it works directly in data allocated in the upper layers like UMS, DFU, THOR. This change is possible since those gadgets now must take care to allocate buffers aligned to cache line (CONFIG_SYS_CACHELINE_SIZE). This can be achieved by using DEFINE_CACHE_ALIGN_BUFFER() or ALLOC_CACHE_ALIGN_BUFFER() macros. Those take care to allocate buffer aligned to cache line in both starting address and its size. Sometimes it is enough to just use memalign() with size being a multiplication of cache line size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removed obscure restriction on the HW setting of DMA transfers. Before this change each transaction sent up to 512 bytes (with packet count equal to 1) for non EP0 transfer. Now it is possible to setup DMA transaction up to DMA_BUFFER_SIZE.

* | | usb:udc:samsung: Remove redundant cache operation from Samsung UDC driverLukasz Majewski2014-02-06-17/+0

Cache cleanups presented above don't contribute much to transmission speed up, hence shall be regarded as cosmetic changes. 3. setdma_rx - here the s3c UDC driver's internal buffers were invalidated. This call is not needed anymore since we reuse the buffers passed from gadgets. This is a key contribution to transmission speed improvement.
