* fs: add sync_inode_metadataChristoph Hellwig2010-10-2510-41/+30
| | | | | | | | | | | Add a new helper to write out the inode using the writeback code, that is including the correct dirty bit and list manipulation. A few of filesystems already opencode this, and a lot of others should be using it instead of using write_inode_now which also writes out the data.

Key differences introduced here: - The old buffer list scheme is no longer required - The original code maintained mac address per rx channel, even if only one rx channel was being used. With this change, mac address is maintained device wide. If support for multiple rx channels is added in future, this will need to be reworked a bit. - The new CPDMA code handles short packets better than before. The earlier code was adjusting the length up, without ensuring that the tail end of the padding was cleared - a possible security issue. This has been fixed to use skb_padto().

Earlier, AEMIF configuration was being done as a special case for DM644x board, but now more boards emerge which have capability to boot for other media (SPI flash, NOR flash) and have the kernel access NAND flash. This means that kernel cannot always depend on the bootloader to setup the NAND. Also, on platforms such as da850/omap-l138, the aemif input frequency changes as cpu frequency changes; necessiating re-calculation of timimg values as part of cpufreq transtitions. This patch forms the basis for adding that support.

Since this capability is useful both from NOR and NAND flashes, it is provided as a new interface and in a file of its own. AEMIF timing configuration is required in cases: 1) Where the AEMIF clock rate can change at runtime (a side affect of cpu frequency change). 2) Where U-Boot does not support NAND/NOR but supports other media like SPI Flash or MMC/SD and thus does not care about setting up the AEMIF timing for kernel to use. 3) Where U-Boot just hasn't configured the timing values and cannot be upgraded because the box is already in the field. Since there is now a header file for AEMIF interface, the common (non-NAND specific) defines for AEMIF registers have been moved from nand.h into the newly created aemif.h Signed-off-by: Sekhar Nori <nsekhar@ti.com> Acked-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CPGMAC pin list in da850.c was incorrectly split into two MII/RMII mode specific pin lists, while what pin group is used is a function of how the board is wired. Copy the pin lists to board-da850-evm.c, renaming them accordingly, and merge the two lists in da850.c into one, da850_cpgmac_pins[], representing the CPGMAC module as a whole...

| | | | | | | | | | | | | | | | | | | | | | | | | | | This is a bugfix for the original tnetv107x submission series. The psc_regs base array was being discarded post-init, and this was causing a crash during post-init clock enable/disable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On OMAP-L138 SoC, some of the sysclks need not be at a fixed ratio to CPU clock and can be kept at a relatively constant rate by adjusting the PLLDIVn ratio even as cpufreq goes ahead and changes the CPU clock. This feature can be used to keep the EMIFA (PLL0 SYSCLK3) clock at a constant rate so that the EMIF timings need not be re-programmed whenever the CPU frequency changes. This patch adds the required suppport to cpufreq driver. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting sysclk rate will be useful in cases where the sysclk is not at a fixed ratio to the PLL output but can asynchronously be changed. This support forms the basis of attempt to keep the AEMIF clock constant on OMAP-L138 even as PLL0 output changes as ARM clock is changed to save power. This patch has been tested on OMAP-L138.

The Sitara AM18x SoCs from TI are an OMAP-L138 pin-to-pin compatible ARM9 microprocessor offering from TI. More information about these processors available at: www.ti.com/am1x Because of their compatibiliy with OMAP-L1x, the kernel support for OMAP-L1x is fully relevant to AM1x processors. This patch updates the Kconfig prompt and help text to include the AM1x part names to help users select configurations required for these parts easily. Also, the hardware information that shows up in /proc/cpuinfo is updated to show applicability of the respective OMAP-L1x EVMs for AM1x parts.
