along struct pci_channel These patches rework the pci code for the sh architecture. Currently each board implements some kind of ioport to address mapping. Some boards use generic_io_base others try passing addresses as io ports. This is the first set of patches that try to unify the pci code as much as possible to avoid duplicated code. This will in the end lead to fewer lines board specific code and more generic code. This patch makes sure a struct pci_channel pointer is passed along to various pci functions such as pci_read_reg(), pci_write_reg(), pci_fixup_pcic(), sh7751_pcic_init() and sh7780_pcic_init().

Code is added to call this init function from pcibios_init(). Return values are adjusted and a warning is is printed if init fails.

The SH7780 PCI host controller implements a configuration header that requires a fair bit of hand-holding to initialize properly. By default it appears as a pre-2.0 host controller given the zeroed out class code, so fix this up properly. Some boards that happened to be using the R7780RP version of the PCIC fixups had set this correctly, but this belongs in the standard initialization, and is by no means board specific.

This consolidates the pci_iomap() definitions and reworks how the I/O port base is handled. PCI channels can register their own I/O map base, or if none is provided, the system-wide generic I/O base is used instead. Functionally nothing changes, while this allows us to kill off lots of I/O address special casing and lookups.

The RTS7751R2D_1 boards only support 1MB of socket-mounted MBM29F040 flash, which we just leave alone as it's not terribly interesting. This adds support for the s29gl256p on the r2d+ boards that makes a bit more sense to expose to the user.

Good things about this change: - interrupts: they are enabled at late_time_init() - mm: regular kmalloc() can be used at late_time_init() Together with moving to late_time_init() this patch changes the sh_cmt driver to always allocate with kmalloc().

If multiple CMT channels are enabled using platform data, use the earlytimer parameter on the kernel command line to select channel. For instance, use "earlytimer=sh_cmt.0" to select the first channel. To verify which timer is being used, look at printouts or the timer irq count in /proc/interrupts.

Clocksource drivers can save power by using keeping the device clock disabled while the clocksource is unused. In practice this means that the enable() and disable() callbacks perform clk_enable() and clk_disable(). The enable() callback may also use clk_get_rate() to get the clock rate from the clock framework. This information can then be used to calculate the shift and mult variables. Currently the mult_orig variable is setup from mult at registration time only. This is conflicting with the above case since the clock is disabled and the mult variable is not yet calculated at the time of registration. Moving the mult_orig setup code to clocksource_enable() allows us to both handle the common case with no enable() callback and the mult-changed-after-enable() case.

The MTU2 driver is a platform driver with early platform support to allow using a MTU2 channel as only clockevent during system bootup. Clocksource on sh2a is currently unsupported due to code generation issues with 64-bit math, so at this point only periodic clockevent support is in place.

If multiple MTU channels are enabled using platform data, use the earlytimer parameter on the kernel command line to select channel. For instance, use "earlytimer=sh_mtu2.0" to select the first channel. To verify which timer is being used, look at printouts or the timer irq count in /proc/interrupts.

There is no real distinction here in behaviour, either a clock needs to be enabled on initialiation or not. The ALWAYS_ENABLED flag was always intended to only apply to clocks that were physically always on and could simply not be disabled at all from software. Unfortunately over time this was abused and the meaning became a bit blurry. So, we kill off both of all of those paths now, as well as the newer NEEDS_INIT flag, and consolidate on a CLK_ENABLE_ON_INIT. Clocks that need to be enabled on initialization can set this, and it will purposely enable them and bump the refcount up.

The only user for this is the SH-Mobile r_clk, which is now added as a root clock and can be kicked via propagate_rate() as usual. Given that, there is no longer any need for the special clk_recalc_rate(), so we kill it off.

If multiple TMU channels are enabled using platform data, use the earlytimer parameter on the kernel command line to select channel. For instance, use "earlytimer=sh_tmu.0" to select the first channel. To verify which timer is being used, look at printouts or the timer irq count in /proc/interrupts.

This adds support for constructing a rate table by looking at potential divisors for a specified clock. Each FQRMR clock is given its own table. Presently each table is rebuilt when the parent propagates down a new rate, so some more logic needs to be added to do this more intelligently. Additionally, a fairly generic round_rate() implementation is then layered on top of it, which subsequently provides us with cpufreq support.

Additionally, this makes it impossible to share hd64461 code alongside generic drivers (in the case of sh_dac_audio), so simply make it commonly defined and permit the mach_is_foo() logic to work out the proper semantics.

This hooks in irq_to_desc_alloc_cpu() to the necessary code paths in the intc and ipr controller registration paths. As these are the primary call paths for all SH CPUs, this alone will make all CPUs sparse IRQ ready. There is the added benefit now that each CPU contains specific IPR and INTC tables, so only the vectors with interrupt sources backing them will ever see an irq_desc instantiation. This effectively packs irq_desc down to match the CPU, rather than padding NR_IRQS out to cover the valid vector range. Boards with extra sources will still have to fiddle with the nr_irqs setting, but they can continue doing so through the machvec as before.

This adds a new SH_CLK_CPG for parts that have CPG support. SH_CLK_CPG_LEGACY is made to depend on this, and still needs to be set for platforms that want clock-cpg to register the legacy clocks. With this new config item in place, it is now possible to start layering more generic CPG code in place while other platforms transition off of the legacy clocks.
