| * [ARM] pxa: introduce reset_status and clear_reset_status for driver's usageEric Miao2008-08-04
| | | | | | | | | | | | | | | | | | | | | | | | Due to the problem of reset status bits being handled by different registers between pxa2xx and pxa3xx, introduce a global reset_status variable, initialized by SoC-specific code and later being used by other drivers. And also introduce clear_reset_status(), which is used to clear the corresponding status bits. Pass RESET_STATUS_ALL to clear all bits. Signed-off-by: Eric Miao <eric.miao@marvell.com>

| | * [ARM] pxa: separate PXA25x and PXA27x UDC register definitionsRussell King2008-05-19
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PXA25x and PXA27x USB device controller register definitions are different. Currently, they live side by side in pxa-regs.h, but only one set is available depending on the setting of PXA25x or PXA27x. This means that if we build to support both PXA25x and PXA27x, the PXA27x definitions are unavailable, even to PXA27x specific code. Remove these definitions from pxa-regs.h, and place them in separate files. Include these files where appropriate. Note: according to the dependencies in drivers/usb/gadget/Kconfig, we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the platform devices from pxa27x.c and pxa3xx.c.

|/ | | | | | | | | | | Patch mainly from Eric Miao, with minor edits by rmk. Note: PWM0 and PWM2 share the same register I/O space and clock gating on pxa{27x, 3xx}, thus PWM2 is treated in the driver as a child PWM of PWM0. And this is also true for PWM1/3.

| | | | | | | | | | | Each time a pxa type cpu went in suspend, a portion of kmalloc memory was corrupted.

* [ARM] pxa: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into oneeric miao2008-04-19
| | | | | | | | | | | | | | | | | | | | | This makes the code better organized and simplified a bit. The change will lose a bit of performance when performing IRQ ack/mask/unmask,but that's not too much after checking the result binary. This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by carefully not to access those pxa{27x,3xx} specific registers, this is done by keeping an internal IRQ number variable. The pxa-regs.h is also modified so registers for IRQ > PXA_IRQ(31) are made public even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake) The incorrect assumption in the original code that internal irq starts from 0 is also corrected by comparing with PXA_IRQ(0). "struct sys_device" for the IRQ are reduced into one single device on pxa{27x,3xx}. Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 4824/1: pxa: clear RDH bit after any resetDmitry Krivoschekov2008-02-09
| | | | | | | | | | | | | | | | | | | | According to PXA300/310 and PXA320 Developer manuals, the ASCR[RDH] "bit needs to be cleared as part of the software initialization coming out of any reset and coming out of D3". The latter requirement is addressed by commit "c4d1fb627ff3072", as for the former (coming out of any reset), the kernel relies on boot loaders and assumes that RDH bit is cleared there. Though, not all bootloaders follow the rule so we have to clear the bit in kernel. We clear the RDH bit in pxa3xx_init() function since it is always invoked after any reset. We also preserve D1S, D2S and D3S bits from being cleared in case we invoke pxa3xx_init() function not from normal hardware reset (e.g. kexec scenario), so these bits can be properly referenced later.

| * [ARM] pxa: Add PXA3 standby code hooked into the IRQ wake schemeRussell King2008-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wakeup sources on PXA3 are enabled at two levels. First, the MFP configuration has to be set to enable which edges a specific pin will trigger a wakeup. The pin also has to be routed to a functional unit. Lastly, the functional unit must be enabled as a wakeup source in the appropriate AD*ER registers (AD2D0ER for standby resume.) This doesn't fit well with the IRQ wake scheme - we currently do a best effort conversion from IRQ numbers to functional unit wake enable bits. For instance, there's several USB client related enable bits but there's no corresponding IRQs to determine which you'd want. Conversely, there's a single enable bit covering several functional units. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
