2009-12-14mfd: Add support for twl6030 irq frameworkBalaji T K
This patch adds support for phoenix interrupt framework. New iInterrupt status register A, B, C are introduced in Phoenix and are cleared on write. Due to the differences in interrupt handling with respect to TWL4030, twl6030-irq.c is created for TWL6030 PMIC Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Balaji T K <balajitk@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Reviewed-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-12-11omap3: Fix OMAP35XX_REV macrosSanjeev Premi
In original implementation, the revision passed to these macros contained revision number in lower nibble. But, later the revision bits (OMAP_REVBITS_XX) were defined to use omap_revision[15:08] where revision number is containied in higher nibble. This patch updates the macros; else incorrect revision is detected for OMAP35xx devices. Signed-off-by: Sanjeev Premi <premi@ti.com>

2009-12-11OMAP3 hwmod: Add automatic OCP_SYSCONFIG AUTOIDLE handlingPaul Walmsley
This patch fills in the OCP_SYSCONFIG.AUTOIDLE handling in the OMAP hwmod code. After this patch, the hwmod code will set the module AUTOIDLE bit (generally <module>.OCP_SYSCONFIG.AUTOIDLE) to 1 by default upon enable. If the hwmod flag HWMOD_NO_OCP_AUTOIDLE is set, AUTOIDLE will be set to 0 upon enable. Upon module disable, AUTOIDLE will be set to 1. Enabling module autoidle should save some power. The only reason to not set the OCP_SYSCONFIG.AUTOIDLE bit is if there is a bug in the module RTL, e.g., the MPUINTC block on OMAP3. Comments from Kevin Hilman <khilman@deeprootsystems.com> inspired this patch, and Kevin tested an earlier version of this patch.

VRFB rotation engine is a block in OMAP2/3 that offers 12 independent contexts that can be used for framebuffer rotation. Each context has a backend area of real memory, where it stores the pixels in undisclosed format. This memory is offered to users via 4 virtual memory areas, which see the same memory area in different rotation angles (0, 90, 180 and 270 degrees).
