2007-07-12[ARM] pxa: move device registration into CPU-specific fileRussell King4-76/+83
This allows individual CPU support to determine which platform devices should be registered. Also fix a copy-n-paste bug in the I2C power platform device entry. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] pxa: remove boot time RTC initialisationRussell King1-9/+0
The RTC library code contains everything necessary to set the system time from the RTC; for similar reasons as the previous commit, it's far better to let the RTC library code sort this out rather than implement something which might not be appropriate for everyone.

2007-07-12[ARM] pxa: stop doing our own rtc management over suspendRussell King1-10/+0
Remove the RTC management over a suspend/resume cycle. Firstly, we may not be using the internal RTC for time keeping; some platforms have an external RTC for this inspite of the PXA having an internal RTC. Secondly, the RTC library code handles updating system time on resume. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4451/1: pxa: make dma.c generic and remove cpu specific dma codeEric Miao3-13/+39
Since the number of dma channels varies between pxa25x and pxa27x, it introduces some specific code in dma.c. This patch moves the specific code to pxa25x.c and pxa27x.c and makes dma.c more generic. 1. add pxa_init_dma() for dma initialization, the number of channels are passed in by the argument 2. add a "prio" field to the "struct pxa_dma_channel" for the channel priority, and is initialized in pxa_init_dma() 3. use a general priority comparison with the channels "prio" field so to remove the processor specific pxa_for_each_dma_prio macro, this is not lightning fast as the original one, but it is acceptable as it happens when requesting dma, which is usually not so performance critical Signed-off-by: eric miao <eric.miao@marvell.com> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

/* should be ok this time, I aligned this patch to your arm:pxa2.mbox */ 1. move pxa25x specific IRQ initialization code to pxa25x_init_irq() and pxa27x code to pxa27x_init_irq(), remove pxa_init_irq() 2. replace all pxa_init_irq() with their PXA25x or PXA27x specific functions Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4438/1: PXA: remove #ifdef .. #endif from pxa_gpio_demux_handler()Eric Miao1-6/+4
1. use GPIO_IRQ_mask[] to select those bits of interest, actually only those "unmasked" GPIO IRQs with their corresponding bits in GPIO_IRQ_mask[] set to "1" should be checked 2. remove #ifdef PXA_LAST_GPIO > 96 .. #endif, GPIO_IRQ_mask[] is used to mask out the irrelevant bits, so that even though the GEDR3 on PXA25x is reserved, it will be masked, and the following code will never run. Another point is that GPIO85- GPIO95 bits within GEDR2 will also be masked out on PXA25x Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-07-12[ARM] 4435/1: PXA: remove PXA_INTERNAL_IRQSEric Miao1-10/+16
1. define PXA_GPIO_IRQ_BASE to be right after the internal IRQs, and define PXA_GPIO_IRQ_NUM to be 128 for all PXA2xx variants 2. make the code specific to the high IRQ numbers (32..64) to be PXA27x specific 3. add a function pxa_init_irq_high() to initialize the internal high IRQ chip, the invoke of this function could be moved to PXA27x specific initialization code Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4434/1: PXA: remove PXA_IRQ_SKIPEric Miao1-5/+5
1. PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ starts from zero. This makes IRQ numbering inconsistent between PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX definition has the same value on both PXA25x and PXA27x. 2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this avoids unintentional use of these macros on PXA25x Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] pxa: Fix PXA27x suspend type validation, remove pxa_pm_prepare()Russell King2-26/+6
pxa_pm_prepare() tried to validate the suspend method type. As noted in previous commits: eb9289eb20df6b54214c45ac7c6bf5179a149026 9c372d06ce9ddf65e1393f9ea22a6d6bd5f96b42 e8c9c502690efd24b7055bf608e7a3c34216848b the checking of the suspend type in the 'prepare' method is the wrong place to do this; use the 'valid' method instead. This means that pxa_pm_prepare() can be entirely removed. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] pxa: move pm_ops structure into CPU specific filesRussell King3-29/+34

2007-07-12[ARM] pxa: remove useless pxa_pm_finish() functionRussell King1-11/+0
pxa_pm_finish() does nothing but return zero. The core code does nothing with this return value, and will not try to call the finish method in the pm_ops structure if it is NULL. Therefore, we can remove this useless function. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-05-01power management: implement pm_ops.valid for everybodyJohannes Berg1-0/+1
Almost all users of pm_ops only support mem sleep, don't check in .valid and don't reject any others in .prepare so users can be confused if they check /sys/power/state, especially when new states are added (these would then result in s-t-r although they're supposed to be something different). This patch implements a generic pm_valid_only_mem function that is then exported for users and puts it to use in almost all existing pm_ops.

2007-05-01rework pm_ops pm_disk_mode, kill misuseJohannes Berg1-4/+0
This patch series cleans up some misconceptions about pm_ops. Some users of the pm_ops structure attempt to use it to stop the user from entering suspend to disk, this, however, is not possible since the user can always use "shutdown" in /sys/power/disk and then the pm_ops are never invoked. Also, platforms that don't support suspend to disk simply should not allow configuring SOFTWARE_SUSPEND (read the help text on it, it only selects suspend to disk and nothing else, all the other stuff depends on PM). The pm_ops structure is actually intended to provide a way to enter platform-defined sleep states (currently supported states are "standby" and "mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured) allows a platform to support a platform specific way to enter low-power mode once everything has been saved to disk. This is currently only used by ACPI (S4). This patch: The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really seems to understand what it actually does. This patch clarifies the pm_disk_mode description. It also removes all the arm and sh users that think they can veto suspend to disk via pm_ops; not so since the user can always do echo shutdown > /sys/power/disk, they need to find a better way involving Kconfig or such. ACPI is the only user left with a non-zero pm_disk_mode. The patch also sets the default mode to shutdown again, but when a new pm_ops is registered its pm_disk_mode is selected as default, that way the default stays for ACPI where it is apparently required.

2007-04-22[ARM] 4304/1: removes the unnecessary bit number from CKENnn_XXXXEric Miao6-15/+15
This patch removes the unnecessary bit number from CKENnn_XXXX definitions for PXA, so that CKEN0_PWM0 --> CKEN_PWM0 CKEN1_PWM1 --> CKEN_PWM1 ... CKEN24_CAMERA --> CKEN_CAMERA The reasons for the change of these defitions are: 1. they do not scale - they are currently valid for pxa2xx, but definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera instead of bit 24 2. they are unnecessary - the peripheral name within the definition has already announced its usage, we don't need those bit numbers to know which peripheral we are going to enable/disable clock for 3. they are inconvenient - think about this: a driver programmer for pxa has to remember which bit in the CKEN register to turn on/off Another change in the patch is to make the definitions equal to its clock bit index, so that #define CKEN_CAMERA (24) instead of #define CKEN_CAMERA (1 << 24) this change, however, will add a run-time bit shift operation in pxa_set_cken(), but the benefit of this change is that it scales when bit index exceeds 32, e.g., pxa3xx has two registers CKENA and CKENB, totally 64 bit for this, suppose CAMERA clock enabling bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10) and so that pxa_set_cken() need minimum change to adapt to that.

Here's a 63-bit implementation of shed_clock() for PXA2xx. The actual period depends on the value of CLOCK_TICK_RATE and whether or not reduced scaling factors were provided for it. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-12-05WorkQueue: Fix up arch-specific work items where possibleDavid Howells1-3/+3
Fix up arch-specific work items where possible to use the new work_struct and delayed_work structs. Three places that enqueue bits of their stack and then return have been marked with #error as this is not permitted. Signed-Off-By: David Howells <dhowells@redhat.com>
2006-12-03[ARM] 3881/4: xscale: clean up cp0/cp1 handlingLennert Buytenhek2-9/+2
XScale cores either have a DSP coprocessor (which contains a single 40 bit accumulator register), or an iWMMXt coprocessor (which contains eight 64 bit registers.) Because of the small amount of state in the DSP coprocessor, access to the DSP coprocessor (CP0) is always enabled, and DSP context switching is done unconditionally on every task switch. Access to the iWMMXt coprocessor (CP0/CP1) is enabled only when an iWMMXt instruction is first issued, and iWMMXt context switching is done lazily. CONFIG_IWMMXT is supposed to mean 'the cpu we will be running on will have iWMMXt support', but boards are supposed to select this config symbol by hand, and at least one pxa27x board doesn't get this right, so on that board, proc-xscale.S will incorrectly assume that we have a DSP coprocessor, enable CP0 on boot, and we will then only save the first iWMMXt register (wR0) on context switches, which is Bad. This patch redefines CONFIG_IWMMXT as 'the cpu we will be running on might have iWMMXt support, and we will enable iWMMXt context switching if it does.' This means that with this patch, running a CONFIG_IWMMXT=n kernel on an iWMMXt-capable CPU will no longer potentially corrupt iWMMXt state over context switches, and running a CONFIG_IWMMXT=y kernel on a non-iWMMXt capable CPU will still do DSP context save/restore. These changes should make iWMMXt work on PXA3xx, and as a side effect, enable proper acc0 save/restore on non-iWMMXt capable xsc3 cores such as IOP13xx and IXP23xx (which will not have CONFIG_CPU_XSCALE defined), as well as setting and using HWCAP_IWMMXT properly.

2006-11-30[ARM] 3940/1: don't reset PXA2xx clock counterNicolas Pitre1-3/+4
Don't reset OSCR to zero as this prevents us from having a contiguous time source. The value returned by sched_clock() is reset to zero in the middle of the boot process otherwise, making CONFIG_PRINTK_TIME rather messed up.

2006-10-15[ARM] Fix fallout from IRQ regs changesRussell King1-1/+1
Some ARM platforms were still broken as a result of the IRQ register passing changes, mostly due to a missing linux/irq.h include. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-10-09IRQ: Use the new typedef for interrupt handler function pointersDavid Howells8-9/+9
Use the new typedef for interrupt handler function pointers rather than actually spelling out the full thing each time. This was scripted with the following small shell script: #!/bin/sh egrep -nHrl -e 'irqreturn_t[ ]*[(][*]' $* | while read i do echo $i perl -pi -e 's/irqreturn_t\s*[(]\s*[*]\s*([_a-zA-Z0-9]*)\s*[)]\s*[(]\s*int\s*,\s*void\s*[*]\s*[)]/irq_handler_t \1/g' $i || exit $? done Signed-Off-By: David Howells <dhowells@redhat.com>
