From 3f7e82759c692df473675ed06fb90b20f1f225c3 Mon Sep 17 00:00:00 2001 From: Rhyland Klein Date: Tue, 8 May 2012 11:42:38 -0700 Subject: mfd: Commonize tps65910 regmap access through header This change removes the read/write callback functions in favor of common regmap accessors inside the header file. This change also makes use of regmap_read/write for single register access which maps better onto what this driver actually needs.

This is useful partly to allow further infrastructure to be based on the domains and partly because it makes it much easier to allocate virtual interrupts to devices as we don't need to allocate a contiguous range of interrupt numbers. Convert the wm831x driver over to this infrastructure, using a legacy IRQ mapping if an irq_base is specified in platform data and otherwise using a linear mapping, always registering the interrupts even if they won't ever be used. Only boards which need to use the GPIOs as interrupts should need to use an irq_base. This means that we can't use the MFD irq_base management since the unless we're using an explicit irq_base from platform data we can't rely on a linear mapping of interrupts. Instead we need to map things via the irq_domain - provide a conveniencem function wm831x_irq() to save a small amount of typing when doing so. Looking at this I couldn't clearly see anything the MFD core could do to make this nicer. Since we're not supporting device tree yet there's no meaningful advantage if we don't do this conversion in one, the fact that the interrupt resources are used for repeated IP blocks makes accessor functions for the irq_domain more trouble to do than they're worth.
