From 8726e96fcb29298351c777670742b553ca947508 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 7 Nov 2012 17:07:45 -0700 Subject: ARM: ux500: convert timer suspend/resume to clock_event_device Move ux500's timer suspend/resume functions from struct sys_timer ux500_timer into struct clock_event_device nmdk_clkevt. This will allow the sys_timer suspend/resume fields to be removed, and eventually lead to a complete removal of struct sys_timer.

This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

-- cgit v1.1 From 05ec260edecaf3dc214cff49d43b1ad9b2cbb710 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 7 Feb 2013 10:17:31 +0100 Subject: mfd: db8500-prcmu: update resource passing When trying to get rid of the cross-includes of from different drivers, so we can localize ASIC/CPU detection to the mach-ux500 folder, we run into the way the PRCMU handles base addresses and firmware detection. This patch updates the firmware version detection to pass the required information as platform data instead of relying on cpu_is_* macros. Now the PRCMU base address, the secondary TCDM area, the TCPM area and the IRQ are passed as resources instead of being grabbed from files. Incidentally this also removes part of the reliance on . Further it updates the firmware version detection, since the location of the firmware ID bytes in the designated memory are is now passed from the platform data instead. There is no reason not to include the nice split-off of a struct to hold the firmware information and a separate function to populate it. The patch actually rids the need to use the external db8500_prcmu_early_init call at all, but I'm keepin back that removal as I don't want the patch to be too big.
