It turns out this does not correctly handle level triggered interrupts on the UIC. Specifically, acknowledging an irq on the UIC (i.e. clearing the relevant bit in UIC_SR) will have no effect for a level interrupt which is still asserted by the external device, even if the irq is already masked. Therefore, unlike handle_level_irq() we must ack the interrupt after invoking the ISR (which should cause the device to stop asserting the irq) instead of acking it when we mask it, before the ISR. This patch implements this change, in a new handle_uic_irq(), a customised irq flow handler for the UIC. For edge triggered interrupts, handle_uic_irq() still uses the old flow - we must ack edge triggered interrupt before the ISR not after, or we could miss a second event which occurred between invoking the ISR and acking the irq.

To work around this, keep a software copy of the register instead. Since it's not modified from the mpic itself, it's a feasible solution. Still, keep it under a config option to avoid wasting memory on other platforms.

That commit causes the mpsc's CON_PRINTBUFFER flag to be cleared since udbg should have printed the previous output. I guess we can no longer ignore udbg. :) This patch provides udbg_putc() and udbg_getc() functions for the Marvell mv64x60 chips. These functions are enabled if an mv64x60 port is to be used as the console as determined from the device tree. Signed-off-by: Dale Farnsworth Acked-by: Mark A.

This introduces a new device binding for the CPM and other devices on these boards. Some of the changes include: 1. Proper namespace scoping for Freescale compatibles and properties. 2. Use compatible rather than things like device_type and model to determine which particular variant of a device is present. 3. Give the drivers the relevant CPM command word directly, rather than requiring it to have a lookup table based on device-id, SCC v. SMC, and CPM version. 4. Specify the CPCR and the usable DPRAM region in the CPM's reg property. Boards that do not require the legacy bindings should select CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once all existing boards are converted and tested, the config option can become default y to prevent new boards from using the old model. Once arch/ppc is gone, the config option can be removed altogether.

Keep a global mpc8xx_immr mapping, rather than constantly creating temporary mappings. 2. Look for new fsl,cpm1 and fsl,cpm1-pic names. 3. Always reset the CPM when not using the udbg console; this is required in case the firmware initialized a device that is incompatible with one that the kernel is about to use. 4. Remove some superfluous casts and header includes. 5. Change a usage of IMAP_ADDR to get_immrbase(). 6. Use phys_addr_t, not uint, for dpram_pbase. 7. Various sparse-related fixes, such as __iomem annotations. 8. Remove mpc8xx_show_cpuinfo, which doesn't provide anything useful beyond the generic cpuinfo handler. 9. Move prototypes for 8xx support functions from board files to sysdev/commproc.h.

The way the current CPM binding describes available multi-user (a.k.a. dual-ported) RAM doesn't work well when there are multiple free regions, and it doesn't work at all if the region doesn't begin at the start of the muram area (as the hardware needs to be programmed with offsets into this area). The latter situation can happen with SMC UARTs on CPM2, as its parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't support moving it. It is now described with a muram node, similar to QE. The current CPM binding is sufficiently recent (i.e. never appeared in an official release) that compatibility with existing device trees is not an issue. The code supporting the new binding is shared between cpm1 and cpm2, rather than remain separated. QE should be able to use this code as well, once minor fixes are made to its device trees.

Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type() (every caller of ucc_init_guemr() also calls ucc_set_type()). Modify all callers of ucc_set_type() accordingly. 2. Remove the unused enum ucc_pram_initial_offset. 3. Refactor qe_setbrg(), also implement work-around for errata QE_General4. 4. Several printk() calls were missing the terminating \n. 5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where appropriate. 6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed with the wrong value. 7. Add the protocol type to struct us_info and updated ucc_slow_init() to use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED. 8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx() 9. Add several macros in qe.h (mostly for slow UCC support, but also to standardize some naming convention) and remove several unused macros. 10. Update ucc_geth.c to use the new macros. 11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol to use when initializing the UCC in ucc_slow_init(). 12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since these are the real names of the registers. 13. Use the setbits, clrbits, and clrsetbits where appropriate. 14. Refactor ucc_set_qe_mux_rxtx(). 15. Remove all instances of 'volatile'. 16. Simplify get_cmxucr_reg(); 17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[]. 18. Updated struct ucc_geth because struct ucc_fast is not padded any more.

This situation hangs MPIC on MPC8568E. To solve this problem efficiently, QEIC needs pluggable handlers, specific to the underlaying interrupt controller. Patch extends qe_ic_init() function to accept low and high interrupt handlers. To avoid #ifdefs, stack of interrupt handlers specified in the header file and functions are marked 'static inline', thus handlers are compiled-in only if actually used (in the board file). Another option would be to lookup for parent controller and automatically detect handlers (will waste text size because of never used handlers, so this option abolished). qe_ic_init() also changed in regard to support multiplexed high/low lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic() handler implemented appropriately.
