Instead, we can pass the MMIO token to the spear clock driver in the initialization routine to contain that knowledge in the platform code itself. Ideally, the clock driver would use of_iomap() or similar to get the address, and that can be used later, but for now, this is the minimal change.

The spear platform is now multiplatform capable in principle, and everything still builds when enabled. This slightly rearranges the Kconfig options for spear to enable both single- and multiplatform support. As a side-effect, even building the single spear kernel can now enable spear3xx and spear6xx simultaneously, although not together with spear13xx, because they are a different archicture version (v7 instead of v5).

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.

Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 19 Mar 2013 15:36:12 +0100 Subject: [PATCH 43/70] 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.

Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select MSM_SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected by default. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.

The multiplatform variant has a number of limitations at the moment: * It only supports DT-enabled machines. This is not a problem in the long run, as non-DT machines for exynos are going away. The main problem here is that the gpio code and the exynos_eint irqchip are not multiplatform capable but still required for ATAGS based boot. * The watchdog driver is still missing a conversion. * sparsemem and memory_holes are currently not supported in multiplatform. The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled for now, as dependent patches are still pending in other subsystem trees. We will enable it once everything comes together.

Turns out that multiplatform breaks some uses cases, such as when you have an existing defconfig, since it adds the new EXYNOS_SINGLE config option as a dependecy. As a result, nearly all exynos config options will be disabled by default. Reverting instead of rebasing since this branch is pulled in as a dependency elsewhere.

This breaks platforms that haven't been converted such as S3C64xx. Revert that part of the change to fix. [arnd: CONFIG_SAMSUNG_SINGLE was actually introduced only for non-multiplatform configurations, but was subsequently removed, which means the driver was now broken both for single- and multi- platform.
