2010-12-14ARM: mach-shmobile: SMP base supportMagnus Damm
Add SMP base support for R-Mobile / SH-Mobile processors. This patch contains all base code to support CONFIG_SMP regardless of ARCH_SHMOBILE processor type. Both local timer and CPU hotplug are supported, but no processor specific code is included. At this point only the default behavior is in place, so a single core will always be used even though CONFIG_SMP is enabled on multicore systems. The SMP Kconfig entry for arch/arm/Kconfig is excluded from this patch to simplify merging. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-12-12ARM: 6528/1: Use CTR for the I-cache line size on ARMv7Catalin Marinas
The current implementation of the v7_coherent_*_range function assumes that the D and I cache lines have the same size, which is incorrect architecturally. This patch adds the icache_line_size macro which reads the CTR register. The main loop in v7_coherent_*_range is split in two independent loops or the D and I caches. This also has the performance advantage that the DSB is moved outside the main loop.

2010-12-12ARM: 6527/1: Use CTR instead of CCSIDR for the D-cache line size on ARMv7Catalin Marinas
The current implementation of the dcache_line_size macro reads the L1 cache size from the CCSIDR register. This, however, is not guaranteed to be the smallest cache line in the cache hierarchy. The patch changes to the macro to use the more architecturally correct CTR register.

After Charu's GPIO hwmod patches, GPIO initialization on N800 emits the following messages for all GPIO banks: omap_hwmod: gpio1: cannot be enabled (3) This is due to OMAP24XX_ST_GPIOS_SHIFT being defined as a bitmask.

aemif_calc_rate() can return a negative error value, so all the variables that get tested for this value need to be signed. The maximum bit width of WSETUP(WSETUP_MAX) appears to be 30 bits (0xf << 26). Using a signed instead of an unsigned integer shouldn't make a difference here.

2010-12-10usb: otg: Adding twl6030-usb transceiver driver for OMAP4430Hema HK
Adding the twl6030-usb transceiver support for OMAP4 musb driver. OMAP4 supports 2 types of transceiver interface. 1. UTMI: The PHY is embedded within OMAP4. The transceiver functionality is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY functionality is embedded within the OMAP4430. There is no direct interactions between the MUSB controller and TWL6030 chip to communicate the session-valid, session-end and ID-GND events. It has to be done through a software by setting/resetting bits in one of the control module register of OMAP4430 which in turn toggles the appropriate signals to MUSB controller. The internal transceiver has functional clocks and powerdown bits to powerdown the PHY for power saving. Since there is no option available for having 2 transceiver drivers for one USB controller, internal PHY specific APIs are passed through plaform_data function pointers to use in the twl6030-usb transceiver driver. 2. ULPI interface is provided for off-chip transceivers.
