From 9a47a8dccf8866b497bd80809da1c665e7b07c2c Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 21 Mar 2013 12:27:25 +0100 Subject: mfd: prcmu: pass a base and size with the early initcall This patch will make an early remapping of the PRCMU, to be used when setting up the clocks, that will call down into parts of the PRCMU driver before it is probed. Going forward this will be removed like this: - The mailbox subsystem need to be merged. http://marc.info/?l=linux-kernel&m=136314559201983&w=2 - At this point the PRCMU clock code can be moved over to the ux500 clock driver in drivers/clk/ux500/* and maintained there in a decentralized manner. - This early initcall and PRCMU base parameters become part of the ux500_clk_init() call instead.

The real resource is already there from the board, so use this to look up the base address instead. Currently the patch is kept minimal so as not to interfere with other work being done on refactoring this driver, but at a later point the defines using (prcmu_base + 0xnnn) need to be replaced by pure offset defined for (0xnnn) and the base inlined with the readl()/writel() and similar codepaths.

1e22a8c614a5d8c29d0882de21ce327673b71fca Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 19 Mar 2013 15:36:12 +0100 Subject: ARM: ux500: move PM-related PRCMU functions to machine We are trying to decompose and decentralize the code in the DB8500 PRCMU out into subdrivers. The code moved in this patch concerns a group of functions used for decoupling and recoupling the IRQs from the GIC. During sleep and idle the Ux500 system will transfer all IRQ handling to the PRCMU using these functions. Basically we are left with the two alternatives of code placement as: - arch/arm/mach-ux500/pm.c - this because the code is closely related to the GIC, and takes ownership of some of the registers from the PRCMU related to this PM functionality. - drivers/mfd/db8500-prcmu-pm.c - because the code is affecting stuff in the PRCMU register range. But then this code needs to remap and handle GIC registers. This patch implementation is taking the first approach. Currently the cpuidle driver is the only piece of code using this set of functions, but it will later also be used by the suspend/resume code which is currently under review. The header file is moved to: The function prototypes need to be placed in a globally visible header since the CPUidle code is planned to move out to drivers/cpuidle.
