* [PATCH] atmel_serial: Pass fixed register mappings through platform_dataHaavard Skinnemoen2006-10-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | In order to initialize the serial console early, the atmel_serial driver had to do a hack where it compared the physical address of the port with an address known to be permanently mapped, and used it as a virtual address. This got around the limitation that ioremap() isn't always available when the console is being initalized. This patch removes that hack and replaces it with a new "regs" field in struct atmel_uart_data that the board-specific code can initialize to a fixed virtual mapping for platform devices where this is possible. It also initializes the DBGU's regs field with the address the driver used to check against. On AVR32, the "regs" field is initialized from the physical base address when this it can be accessed through a permanently 1:1 mapped segment, i.e. the P4 segment. If regs is NULL, the console initialization is delayed until the "real" driver is up and running and ioremap() can be used.

This is useful on production hardware such as the Zaurus cxx00 models where the valid modes are known in advance and any other modes could result in hardware damage. Following this, add support for the cxx00 QVGA mode. Mode information is passed to the lcd_power call to allowing the panel drivers to configure the display hardware accordingly (corgi_lcd already contains the functionality for the cxx00 panel).

* | [PATCH] Directed yield: cpu_relax variants for spinlocks and rw-locksMartin Schwidefsky2006-10-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems running with virtual cpus there is optimization potential in regard to spinlocks and rw-locks. If the virtual cpu that has taken a lock is known to a cpu that wants to acquire the same lock it is beneficial to yield the timeslice of the virtual cpu in favour of the cpu that has the lock (directed yield). With CONFIG_PREEMPT="n" this can be implemented by the architecture without common code changes. Powerpc already does this. With CONFIG_PREEMPT="y" the lock loops are coded with _raw_spin_trylock, _raw_read_trylock and _raw_write_trylock in kernel/spinlock.c. If the lock could not be taken cpu_relax is called. A directed yield is not possible because cpu_relax doesn't know anything about the lock. To be able to yield the lock in favour of the current lock holder variants of cpu_relax for spinlocks and rw-locks are needed. The new _raw_spin_relax, _raw_read_relax and _raw_write_relax primitives differ from cpu_relax insofar that they have an argument: a pointer to the lock structure.

Currently update_times() calculates ticks by "jiffies - wall_jiffies", but callers of do_timer() should know how many ticks to update. Passing ticks get rid of this redundant calculation. Also there are another redundancy pointed out by Martin Schwidefsky. This cleanup make a barrier added by 5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes it. As a bonus, this cleanup make wall_jiffies can be removed easily, since now wall_jiffies is always synced with jiffies. (This patch does not really remove wall_jiffies. It would be another cleanup patch) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "Eric W.

| * | [ARM] 3855/1: Add generic time supportKevin Hilman2006-09-282-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds Generic time-of-day support for the ARM architecture. The support is currently added using #ifdef's so that it can support sub-arches that do not (yet) have a clocksource added. As sub-arches add clocksource support, they should 'select GENERIC_TIME' Signed-off-by: Deepak Saxena <dsaxena@mvista.com> Signed-off-by: Daniel Walker <dwalker@mvista.com> Signed-off-by: Kevin Hilman <khilman@mvista.com> Acked-by: John Stultz <johnstul@us.ibm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * | [ARM] 3870/1: AT91: Start removing static memory mappingsAndrew Victor2006-09-281-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the static memory mapping for the currently-unused peripherals [Synchronous Serial, Timer/Counter unit], and for those drivers that already ioremap() their registers [UART]. Also, the Ethernet driver now uses the platform_device resources but doesn't yet use ioremap() so we need to pass it the virtual address instead of the physical address.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the hardware register definitions for the TWI (I2C) controller found on the AT91RM9200 and AT91SAM9xx processors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the AT91 gpio.c support processor-generic (AT91RM9200 and AT91SAM9xxx). The GPIO controllers supported by a particular AT91 processor are defined in the processor-specific file and are registered with gpio.c at startup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is more preparation for adding support for the new Atmel AT91SAM9 processors. Changes include: - Replace AT91_BASE_* with AT91RM9200_BASE_* - Replace AT91_ID_* with AT91RM9200_ID_* - ROM, SRAM and UHP address definitions moved to at91rm9200.h. - The raw AT91_P[ABCD]_* definitions are now depreciated in favour of the GPIO API.
